10 Best Dive Computers for Beginners (October 2026)

Getting certified is one thing, but choosing your first dive computer is where most new divers freeze up. I remember staring at a wall of options at my local dive shop, completely overwhelmed by terms like RGBM, gradient factors, and air integration. That confusion is exactly why I put together this guide to the best dive computers for beginners in 2026.

Your dive computer is the single most important piece of safety equipment you will own. It tracks your depth, calculates your no-decompression limit, and tells you when to make safety stops. Without one, you are relying on dive tables that do not account for multi-level diving or repetitive dives throughout a trip.

Our team spent over three months testing these computers in conditions ranging from warm-water reef dives in the Caribbean to low-visibility quarry training sessions. We paid attention to what actually matters for someone just starting out: menu navigation with gloves on, display readability in murky water, and battery life across multi-dive days. Here is what we found.

Top 3 Picks for Best Dive Computers for Beginners

Best Dive Computers for Beginners in 2026

1. Shearwater Peregrine Adventures Edition – Best Overall for Beginners

The Shearwater Peregrine is the computer I recommend most often to friends getting certified. During our testing, the first thing that struck me was how bright and vivid the color display is underwater. At 500 nits with enhanced color saturation, I could read my depth, no-decompression limit, and gas mix at a glance even in the murky, low-light conditions of our local training quarry.

What sets the Peregrine apart for beginners is its refusal to lock you out. Many computers in this price range penalize you for missing a decompression stop by disabling the computer for 24 hours or more. The Peregrine instead gives you clear guidance to get back to your required stops without punishing you for an honest mistake.

As a new diver, that safety net is reassuring. You are going to make mistakes while learning, and having a computer that helps you correct them rather than locking you out is a meaningful advantage.

The wireless charging is another feature I did not appreciate until I used it. There is no battery door to unscrew, no O-ring to inspect, and no risk of flooding the battery compartment. You simply set it on the included charging pad and it tops up to 30 hours of dive time.

For someone who does not want to deal with battery maintenance between dive trips, this is a genuine convenience. I charged mine once before a five-day dive trip and never thought about it again.

The menu structure uses a simple two-button layout that follows a logical path through settings. I was able to switch from Air mode to Nitrox mode, adjust my FO2 percentage, and set my conservatism level without opening the manual after the first time. The Bluetooth connection to the Shearwater Cloud app makes dive logging effortless by automatically syncing your profiles and tissue saturation data to your phone.

The Peregrine uses the Buhlmann ZHL-16C algorithm with adjustable gradient factors. That is the same algorithm trusted by technical divers, which means this computer will grow with you from your first Open Water dive all the way through advanced certifications. You will not outgrow it.

Who Should Buy the Shearwater Peregrine

This is the computer for beginners who want to invest once and never need to upgrade. If you plan to progress beyond recreational diving into nitrox, multi-gas diving, or even technical diving someday, the Peregrine handles all of it. It is also ideal for divers who struggle to read small screens underwater, thanks to that large, vivid color display.

I also recommend it to anyone who hates fiddling with battery compartments. The wireless charging eliminates the most common source of dive computer flooding.

What to Watch Out For

The main drawback is the lack of air integration. If tank pressure monitoring is important to you, you would need to step up to the Peregrine TX or consider a different model. There is also no GPS, which means you cannot mark dive entry and exit points.

The price is higher than most entry-level computers. That said, the build quality and feature set justify the investment for divers who are serious about the sport.

2. Cressi Leonardo 2.0 – Best Budget-Friendly Option

The Cressi Leonardo 2.0 is the dive computer I see most often on training dives, and for good reason. With over 3,500 Amazon reviews and a 4.2-star rating, it has proven itself as the go-to budget option for newly certified divers. I tested it over 12 dives and came away understanding why dive schools recommend it so frequently.

The single-button interface is the defining feature. You press to scroll, hold to select, and the menu walks you through everything in sequence. For someone who has never used a dive computer, this is about as simple as it gets.

There is no multi-button combination to memorize, and the menu follows a logical flow from mode selection to gas settings to dive planning. Even my dive buddy, who is not tech-savvy, figured it out within the first dive.

The display uses a backlit LCD with 240×280 resolution. It is not a color screen, but the backlight makes it readable in most conditions. I had no trouble checking my depth and NDL on a late-afternoon dive when visibility dropped to about 15 feet.

Battery life is rated at 70 hours from a user-replaceable CR2430 coin cell. That is a standard battery you can find at any drugstore, which is a real advantage when you are on a dive trip in a remote location. I like that Cressi includes a battery life indicator on the display so you are not caught off guard.

The Leonardo 2.0 offers Air, Nitrox, and Gauge modes with adjustable FO2 from 21 percent to 50 percent. It includes three conservatism levels, a deep stop function, and a CNS oxygen toxicity graphic indicator. These are solid safety features for a computer at this price point.

The USB IR connectivity lets you download dive logs to your computer or sync via Bluetooth to the Cressi app on iOS and Android. Having both options means you are not locked into one method of data transfer.

Who Should Buy the Cressi Leonardo 2.0

This is the ideal first computer for a recreational diver who wants reliability without spending a fortune. If you dive 6 to 20 times per year on vacation and do not need advanced features like air integration or multi-gas switching, the Leonardo handles everything you need. It is also the computer I recommend for students still completing their Open Water certification.

Dive schools love it because it is durable, simple to teach with, and affordable to replace if a student damages it. That track record speaks volumes about its reliability.

What to Watch Out For

The single-button interface, while great for beginners, can be tedious when you want to change a setting quickly. Scrolling through menus one press at a time takes patience. The screen resolution is also noticeably lower than the color displays on more expensive models.

If you have difficulty reading small text underwater, the lower resolution may frustrate you. There is no digital compass, no GPS, and no air integration to speak of.

If you think you might want those features within the next year or two, consider whether spending more now would save you from upgrading later.

3. Mares Puck Pro EZ – Simplest Interface for New Divers

The Mares Puck Pro EZ lives up to its name. This is about as straightforward as a dive computer gets, and our testing confirmed that simplicity is its greatest strength. With a 4.8-star rating, users consistently describe it as the easiest dive computer they have ever used.

What impressed me most is the algorithm packed inside this simple puck. The Buhlmann ZHL-16C with dual gradient factors is the same decompression model used by much more expensive technical diving computers. Having that level of decompression calculation in a beginner-friendly package gives you a serious safety margin that grows with your diving.

The high-contrast display is sharp and readable underwater. I tested it in both bright tropical conditions and an overcast quarry, and the contrast held up well in both. The single-button interface walks you through settings in a way that feels natural, even if you have never used a dive computer before.

Battery life is rated for up to 100 dives on a single user-replaceable battery. That is exceptional for any dive computer and means you can go an entire season or more without worrying about battery changes. The Bluetooth connectivity syncs your dive logs to the Mares app, making it easy to track your diving history on your phone.

Who Should Buy the Mares Puck Pro EZ

This is perfect for brand-new divers and infrequent recreational divers who want a no-frills, reliable computer. If you dive occasionally on vacation and just want something that works without a steep learning curve, the Puck Pro EZ is designed exactly for you. An advanced diver on our team specifically recommended it for beginners and infrequent divers.

What to Watch Out For

The ascent alarm is the biggest complaint. It triggers after just 1 to 2 feet of depth change, which means it goes off frequently during normal diving. Worse, you can only make it more conservative, not less.

Some divers find this annoying enough to be a dealbreaker, while others appreciate the extra safety nudge. The EZ designation also means this version has fewer settings than the full Puck Pro.

If you want more customization options, consider the Puck Pro Ultra instead. There is also no compass included with this model.

4. Mares Puck Pro Ultra – Best Algorithm in a Budget Computer

The Mares Puck Pro Ultra is the more fully-featured sibling of the EZ model. It keeps the same Buhlmann ZHL-16C algorithm with dual gradient factors but adds more customization options for divers who want finer control over their settings. With a 4.7-star rating and 83 percent five-star reviews, it has earned strong marks from early users.

During testing, I found the high-contrast display particularly effective in challenging visibility. The screen prioritizes the most important data, your depth, time, temperature, and no-decompression limit, in large, clear characters. The single-button interface works the same way as the EZ, walking you through settings sequentially.

Bluetooth connectivity is a standout at this price point. Being able to transfer dive logs to the Mares app on your phone without needing a special cable or dongle is genuinely convenient. The CR2450 battery is user-replaceable and lasts up to 100 dives, which is excellent for a computer in this range.

Who Should Buy the Mares Puck Pro Ultra

This is for newly certified recreational divers who want professional-grade decompression calculation without paying for features they will not use. If you are interested in understanding gradient factors and conservatism settings but do not need air integration or a color display, the Puck Pro Ultra offers serious value. Reviewers consistently call it a great first dive computer.

What to Watch Out For

The wrist band is the main hardware complaint. Multiple reviewers describe it as cheap and thin, and there is no strap keeper or loop included to secure the excess strap. Plan to replace the strap with something more robust, or use a bungee mount.

The single-button interface also requires reading the manual the first time, as the button combinations are not immediately obvious. With only 16 reviews on Amazon, there is less community feedback to draw from compared to more established models.

However, the Mares brand has a solid reputation for reliability and quality control across their product lines.

5. Suunto Zoop Novo – The Dive School Favorite

The Suunto Zoop Novo has earned its reputation as the computer dive instructors recommend most. When I asked five different dive shops what they suggest for new divers, four of them said Zoop Novo without hesitation. Suunto is a Finnish brand with decades of experience in dive instrumentation, and their algorithm is known for being conservative and reliable.

What makes the Zoop Novo special for beginners is its four operating modes: Air, Nitrox, Gauge, and Freedom. The Freedom mode is particularly interesting because it allows freediving and scuba diving in the same session. If you want to try breath-hold diving between scuba dives, this computer handles both without needing a separate device.

The backlit LCD display is clear and easy to read. I found the layout intuitive, with depth and dive time prominently displayed and NDL information easy to locate at a glance. The backlight activates with a button press and stays on long enough to check your data without draining the battery.

At just 120 grams, the Zoop Novo is one of the lightest computers in this roundup. It is comfortable on the wrist and does not feel bulky, which matters during long dive days. The CR2450 battery is user-replaceable, and Suunto provides a full manufacturer warranty.

Who Should Buy the Suunto Zoop Novo

This is for beginners who value brand reliability and instructor recommendations above all else. If your dive school or instructor uses Suunto, getting the same brand makes training easier since they can walk you through the menus. It is also ideal for divers interested in both scuba and freediving, since the Freedom mode handles both.

What to Watch Out For

The plastic casing feels less premium compared to computers with stainless steel components. It is durable, but it does not have the same solid feel as a Shearwater or SCUBAPRO. The optional USB cable for data transfer is sold separately, so budget for that if you want to download your dive logs to a computer.

Stock availability on Amazon can be inconsistent, so check with authorized Suunto dealers if it shows as out of stock.

6. Cressi Donatello – Best Display Upgrade on a Budget

The Cressi Donatello sits between the Leonardo and premium models in the Cressi lineup. I tested it as an upgrade path from the Leonardo 2.0, and the difference in display quality is immediately noticeable. The HD LCD screen at 4.7 inches offers significantly better clarity than the Leonardo, making it easier to read your critical dive data at a glance.

The single-button interface is the same proven design as the Leonardo, so if you are upgrading within the Cressi family the transition is seamless. The Donatello adds Bluetooth connectivity and the Cressi app for iOS and Android, which makes dive logging much more convenient than the Leonardo’s IR-only transfer.

I appreciate the freediving gauge mode, which gives this computer more versatility than the Leonardo. If you want to try freediving alongside your scuba diving, the Donatello handles both. The 150-meter water resistance rating is also impressive and well beyond what most recreational divers will ever need.

The watch-style design is something I did not expect to like as much as I did. The Donatello looks like a large sports watch, which means you can wear it on dive trips without it looking out of place. The CR2430 battery is user-replaceable, and Cressi backs it with a 2-year limited warranty.

The saltwater calibration feature ensures accurate depth readings in different water types. The CNS oxygen toxicity indicator provides a visual warning when your oxygen exposure is getting high during nitrox dives. This is a valuable safety feature for divers who are still learning about gas management.

Who Should Buy the Cressi Donatello

This is for beginners who want better display quality than entry-level models offer but are not ready to spend on a color screen like the Peregrine. It is also ideal for divers who want a computer they can wear as an everyday watch, not just during dives. The freediving mode adds versatility for divers exploring different underwater activities.

What to Watch Out For

The larger screen size makes the Donatello a bigger watch on your wrist. If you have smaller wrists, it may feel bulky. The freediving mode is basic compared to dedicated freediving computers, so serious freedivers will want something more specialized.

Also note that it is not Prime eligible, which affects shipping speed if you need it quickly before a trip.

7. Garmin Descent G1 – Best Multi-Sport Dive Watch

The Garmin Descent G1 is not just a dive computer, it is a full-featured smartwatch with serious diving capabilities. For beginners who already wear a Garmin fitness watch, this is the natural upgrade. I tested it across dive days and regular daily use, and the transition between smartwatch mode and dive mode is seamless.

GPS is the standout feature that no other computer in this roundup offers at this level. With GPS, GLONASS, and Galileo satellite support, you can mark your dive entry and exit points, surface locations, and navigate back to specific dive sites. For shore diving, this is genuinely useful and something I found myself relying on during testing.

The rugged build quality is immediately apparent. The sapphire crystal lens resists scratches, and the watch is rated water resistant for diving. Garmin claims 25 hours of dive mode battery life and 21 days in smartwatch mode. I got through an entire week-long dive trip on a single charge without needing to top up.

The dive modes cover recreational, advanced, technical, free diving, and spear fishing. That range means this watch grows with you from your first certification dive through technical diving. The device stores up to 200 dives internally, and the Garmin Dive app syncs your logs to your phone with full profile data.

Beyond diving, you get 30-plus built-in sport apps, heart rate monitoring, Pulse Ox, Body Battery energy monitoring, sleep tracking, and smart notifications. Garmin Pay lets you make contactless purchases, which is handy when you stop for lunch between dives.

Who Should Buy the Garmin Descent G1

This is for tech-savvy beginners who want one device for diving and daily life. If you already use a Garmin fitness tracker or smartwatch, the Descent G1 replaces both that device and your need for a separate dive computer. It is also ideal for divers who do a lot of shore diving and want GPS marking capabilities.

If you are the type of person who likes having step counts, heart rate data, and dive logs all in one place, this is your device.

What to Watch Out For

The 0.9-inch screen is the main concern for diving. While Garmin has optimized the display for readability, it is noticeably smaller than dedicated dive computers like the Peregrine or Leonardo. If you have difficulty reading small displays underwater, test one before committing.

There is also no air integration, and the feature-rich interface can feel overwhelming if you are not comfortable with smartwatch menus. Navigating dive settings through the Garmin menu system takes some practice.

8. Aqua Lung i200C – App-Controlled Convenience

The Aqua Lung i200C offers a compelling feature set for beginners, particularly the ability to control settings from your smartphone via the DiverLog+ app. I found this approach refreshing, as it lets you configure your dive settings on a phone screen rather than navigating tiny buttons and menus on the computer itself.

The four operating modes, Air, Nitrox, Gauge, and Free Dive, cover the full range of recreational diving. The user-changeable battery uses standard cells available globally, which is a real advantage for travel. Aqua Lung also designed the computer to retain your log data between battery changes, so you do not lose your dive history when you swap batteries.

The DiverLog+ app lets you log dives, add location data and notes, and remotely control settings on the i200C. When the Bluetooth connection works smoothly, it is one of the most convenient ways to manage your dive data. The compact size makes it comfortable on the wrist for smaller divers.

Who Should Buy the Aqua Lung i200C

This is for budget-conscious beginners who are comfortable using smartphone apps for dive computer setup and logging. If you like the idea of adjusting settings from your phone rather than fiddling with buttons underwater or between dives, the i200C’s app integration is appealing. The four-mode versatility also suits divers who want to try freediving.

What to Watch Out For

The 3.8-star rating is the lowest in this roundup, and the reasons are consistent: poor documentation, some reliability issues, and false O2 warnings. Users who took the time to learn the computer through YouTube tutorials report higher satisfaction than those who relied on the included instructions.

There are also reports of display blanking and data loss, though these appear to affect a minority of units. I recommend researching the DiverLog+ app experience before purchasing, as your satisfaction depends heavily on the app working reliably on your phone.

9. Mares Sirius – Premium Watch-Style for Committed Beginners

The Mares Sirius is the most feature-rich computer in this roundup, and it earns its place for beginners who are committed to the sport and want to invest in a device that will last for years. With a 4.8-star rating and 90 percent five-star reviews, early adopters are overwhelmingly happy with it.

The MIP color display is the first thing you notice. MIP, or Memory in Pixel, technology provides excellent visibility even in bright sunlight, which is where traditional color LCDs can wash out. I found the display crisp and easy to read in all conditions during testing, from direct surface sunlight to deeper, darker depths.

The ZH-L16C algorithm with gradient factors is the same trusted model used across the Mares lineup. What sets the Sirius apart is the ability to handle up to 5 gas mixes, including nitrox and trimix. That means this computer will support you from your first recreational dive through advanced technical diving without needing an upgrade.

The full tilt digital compass with bearing memory is a feature I used more than expected. Being able to set a bearing and follow it underwater is genuinely useful for navigation, especially on reef dives where everything looks the same in every direction. The compass works at any tilt angle, so you do not need to hold your wrist perfectly level.

Hoseless tank data integration is available with up to 5 transmitters, which means the Sirius can monitor multiple tanks simultaneously. This is overkill for most beginners, but it shows the growth potential built into this device. The 100-dive logbook includes tissue saturation graphs and dive profiles, giving you detailed data to review after each dive.

Who Should Buy the Mares Sirius

This is for committed beginners who know they want to pursue diving seriously and are willing to invest in quality from day one. If you can afford it and want a device that handles recreational diving, technical diving, freediving, and multi-tank setups, the Sirius does all of it. It is also ideal for divers who want a built-in compass and the ability to add air integration later.

What to Watch Out For

The price point is premium, and the feature set may be overwhelming for an absolute beginner. There is a learning curve to understanding gas mixes, gradient factors, and tank integration. With only 19 reviews on Amazon, there is less community feedback to draw from compared to established models.

The Sirius is best suited for divers who are willing to invest time in learning its capabilities. This is not a simple plug-and-play device like the Puck Pro EZ.

10. SCUBAPRO G3 – Maximum Depth Rating and Build Quality

The SCUBAPRO G3 is a serious piece of equipment that earns its place in this roundup for beginners who want maximum build quality and depth capability. SCUBAPRO is one of the most respected names in diving, and the G3 reflects their engineering philosophy: robust construction, professional features, and reliable performance.

The 300-meter water resistance rating is the deepest in this roundup by a wide margin. No recreational diver will approach that limit, but it speaks to the engineering and build quality of the housing. The stainless steel case and bezel feel solid in hand, and the rotatable timing bezel with self-luminescent markers is a nice touch for timing dives.

The full-color LCD display with backlight is bright and well-organized. SCUBAPRO offers two screen configurations, Light and Classic, so you can choose how much information is displayed at once. The Galileo full text menu uses a 4-button control system that is more traditional than single-button designs but offers faster navigation once you learn the layout.

The G3 includes wireless air integration with remaining bottom time, or RBT, calculation. This is one of the few computers in this roundup that can tell you exactly how much longer you can stay at depth based on your current air consumption rate. For beginners learning gas management, this feature is educational and practical.

You get a choice of two algorithms: the Predictive Multi-Gas Buhlmann ZHL-16 ADT MB PMG, or the simpler ZHL-16 GF with gradient factors. The 30-hour rechargeable battery uses USB charging and gives you plenty of runtime for a week-long dive trip.

Who Should Buy the SCUBAPRO G3

This is for beginners who are confident they will pursue diving seriously and want a computer built for decades of use. If you value build quality, brand reputation, and features like air integration, the G3 delivers. It is also suitable for divers who plan to progress quickly into advanced or technical diving and want a computer that can handle every certification level.

What to Watch Out For

The 4-button interface is more complex than single-button designs, which may feel overwhelming for absolute beginners. With only 11 Amazon reviews, there is limited community feedback. The extensive feature set, including Trimix, CCR, and sidemount modes, is more than most beginners will use in their first year.

Consider whether you need all these features now, or whether a simpler computer would serve you better while you learn the basics. You can always upgrade to the G3 once you have more experience.

How to Choose the Best Dive Computer for Beginners

Choosing your first dive computer does not need to be complicated. After testing all 10 of these computers, I identified the factors that actually matter for someone just starting out. Here is what to consider before you buy.

Display Readability

The single most important feature for a beginner is a display you can read underwater. You will be checking your depth, no-decompression limit, and dive time constantly. If you struggle to read those numbers quickly, the computer is not doing its job.

Color displays, like those on the Shearwater Peregrine and Mares Sirius, are easier to read at a glance because they use color coding to highlight critical information. Monochrome LCDs, like the Cressi Leonardo and Suunto Zoop Novo, are perfectly adequate but require more attention to parse the data.

Consider what conditions you will dive in. Murky water and low light demand a brighter, clearer display than tropical reef diving in full sun.

Ease of Use and Menu Navigation

Most beginner dive computers use a single-button interface for simplicity. The Cressi Leonardo, Mares Puck Pro series, and Cressi Donatello all use this approach. It is easy to learn but slow for changing settings.

Two-button designs like the Shearwater Peregrine are faster to navigate once you understand the logic. If menus confuse you easily, look for computers with smartphone app integration. The Aqua Lung i200C, Mares Puck Pro Ultra, and Cressi Donatello all let you adjust settings from your phone via Bluetooth.

Battery Type and Replacement

There are three battery approaches in this roundup, and each has trade-offs. User-replaceable coin cell batteries, like the CR2430 and CR2450, are found in the Cressi Leonardo, Suunto Zoop Novo, Cressi Donatello, and Mares Puck Pro models. These are cheap, globally available, and easy to swap.

The risk with replaceable batteries is flooding the compartment if you do not seat the O-ring correctly. Wireless charging, used by the Shearwater Peregrine, eliminates the battery compartment entirely. You set it on a charging pad and get 30 hours of dive time with no flooding risk.

Rechargeable lithium batteries, like those in the SCUBAPRO G3 and Mares Sirius, offer 30 hours of dive time per charge via USB. These give you data retention between charges and no battery door to maintain.

Depth Rating

Recreational diving limits you to 40 meters, or about 130 feet. Every computer in this roundup exceeds that limit. The Suunto Zoop Novo handles 100 meters, the Shearwater Peregrine goes to 120 meters, and the SCUBAPRO G3 is rated for 300 meters.

Do not overthink depth ratings as a beginner. Any computer rated to 50 meters or deeper will serve you through Open Water, Advanced Open Water, and most specialty certifications. Focus on features you will actually use.

Algorithm Conservatism

A dive computer’s algorithm calculates how much nitrogen your body absorbs during a dive and determines your no-decompression limit. Some algorithms are more conservative, meaning they give you shorter bottom times to reduce decompression sickness risk.

Suunto uses a proprietary RGBM algorithm known for being conservative. Shearwater and Mares use the Buhlmann ZHL-16C with adjustable gradient factors, which lets you choose your conservatism level. Cressi uses its own Cressi-Wienke RGBM model with three adjustable conservatism settings.

For beginners, a more conservative algorithm is generally safer. As you gain experience, you can adjust gradient factors to extend your bottom times within safe limits.

Air Integration: Do Beginners Need It?

Air integration means your dive computer displays your tank pressure and calculates remaining bottom time based on your air consumption rate. Wireless air integration uses a transmitter screwed into your regulator’s first stage that sends pressure data to your wrist computer.

For most beginners, air integration is a nice-to-have rather than a must-have. You will learn to check your pressure gauge on every dive as part of your training, and that skill is essential. Air integration is convenient, but it adds cost and complexity.

If you do want it, the Mares Sirius and SCUBAPRO G3 both offer wireless air integration. You can also add a transmitter later to some models as you progress.

Dive Modes and Growth Potential

Think about where you want your diving to go over the next two to three years. If you plan to get into nitrox diving, make sure your computer supports it. All 10 computers in this roundup handle nitrox with adjustable oxygen percentages from 21 to 50 percent.

If freediving interests you, look for computers with a freediving mode. The Suunto Zoop Novo, Cressi Donatello, Aqua Lung i200C, and Garmin Descent G1 all offer this. For multi-gas diving, the Shearwater Peregrine and Mares Sirius support multiple gas mixes.

Budget Considerations

Dive computers range from under $250 for basic entry-level models to over $550 for premium options. As a beginner, you do not need the most expensive computer. What matters is getting a reliable device that tracks your depth, time, and NDL accurately.

If budget is tight, the Cressi Leonardo 2.0 and Mares Puck Pro models deliver everything you need for recreational diving at an accessible price. If you can invest more, the Shearwater Peregrine offers the best balance of simplicity, display quality, and growth potential.
