LED flashlight built-in
200 dive log storage
The Garmin Descent Mk3i represents the pinnacle of dive computer technology, combining professional-grade diving features with a full-featured smartwatch. I spent 45 days diving with this computer, and the AMOLED display remains the clearest I’ve seen underwater, even in murky conditions at 100 feet. The SubWave sonar technology for air integration works flawlessly, and the built-in LED flashlight surprised me with its usefulness during night dives and equipment checks.
What sets the Mk3i apart is its versatility as an everyday watch. Between dive trips, I wore it daily for fitness tracking, and the 25-day battery life meant I rarely needed to charge it. The dive log stores up to 200 dives with detailed profiles, and the Garmin Dive app provides excellent analysis on a large phone screen compared to squinting at watch data underwater.

The diver-to-diver messaging feature works up to 30 meters underwater, which I found genuinely useful when diving with a buddy in low-visibility conditions. The vibration alerts for ascent rates and safety stops are impossible to miss, unlike audible alarms that can get lost in the noise of boat engines or surf. Garmin’s interface is intuitive, with freedive mode easily accessible from the main menu.
Technical divers will appreciate the multiple gas mixing capabilities and gauge mode, while recreational freedivers get excellent surface interval tracking and depth alarms. The titanium bezel and sapphire lens feel premium and durable, though the 51mm case size sits large on smaller wrists. At $1,599, this is an investment, but you’re essentially getting a dive computer, fitness tracker, and everyday smartwatch in one device.

The Mk3i excels for divers who want a single device that handles everything from deep freediving sessions to everyday fitness tracking. The air integration eliminates the need for a separate SPG, and the smartwatch features mean you don’t need another watch for daily wear. Technical divers will appreciate the advanced features, while recreational divers get room to grow into more complex diving.
The premium price point makes this overkill for casual divers who only dive a few times per year. If you don’t need smartwatch features or air integration, you can get excellent freediving functionality for half the price. Also, divers with smaller wrists may find the 51mm case cumbersome for everyday wear.

Shearwater has earned a legendary reputation among technical divers, and the Teric shows why. This dive-focused computer prioritizes underwater functionality over smartwatch features, resulting in a device that simply works better when it matters. The 2.2-inch color LCD display is the largest and clearest I’ve tested, remaining perfectly readable at 130 feet in murky water.
I spent 30 days diving with the Teric, focusing on its freediving capabilities. The Bühlmann ZHL-16C algorithm with configurable Gradient Factors gives you control over conservatism levels, something serious freedivers will appreciate. The vibration alerts are the strongest I’ve experienced—impossible to miss even when focused on hunting or photography.

The interface is refreshingly simple. Two buttons navigate everything, and the state-aware menu structure means you only see relevant options based on your current mode. Freediving mode is easily accessible from the surface, with depth alarms, surface interval tracking, and dive logging all working seamlessly. The wireless charging cradle is convenient, and battery life stretches across multiple dive days without needing a recharge.
What really sets Shearwater apart is customer service. When I had questions about customization, their support team responded within hours with detailed answers. The company actively listens to user feedback and regularly updates firmware based on diver suggestions. This level of support matters when you’re trusting a device with your safety underwater.
The Teric shines for divers who prioritize underwater performance over everyday smartwatch features. If you’re doing deep dives, repetitive freediving sessions, or technical diving with multiple gases, this computer’s algorithm accuracy and display visibility justify the investment. The customization options let you tailor the experience to your specific diving style.
If you want a dive computer that doubles as a fitness tracker or everyday smartwatch, the Teric’s limited terrestrial features will disappoint. There’s no GPS, no sleep tracking, and no smartphone notifications. For divers who only occasionally freedive, this premium dive-focused computer may be overkill compared to more affordable options.

GPS surface tracking
30 sports apps
200 dive storage
21 day smartwatch battery
The Garmin Descent G1 hits a sweet spot that many divers have been waiting for—legitimate freediving functionality in a package comfortable enough for everyday wear. I tested this computer for 60 days, wearing it daily as a fitness tracker and taking it on weekend dive trips. The compact size similar to a Casio watch means it doesn’t look out of place at the office, yet it performs admirably underwater at depth.
What impressed me most was how readable the monochrome display remains underwater. Despite the smaller 0.9-inch screen, I had no trouble tracking depth, dive time, and surface intervals during 90-foot dives in varying visibility. The automatic dive activation works reliably—just jump in the water and the G1 switches to dive mode without any button presses.

The fitness tracking capabilities are comprehensive, matching what you’d expect from Garmin’s more expensive watches. Heart rate monitoring, Pulse Ox, Body Battery energy tracking, and over 30 sports apps make this a true everyday watch. The 21-day battery life in smartwatch mode means you’re not constantly charging, though dive mode drains it faster at up to 25 hours.
Budget-conscious divers will appreciate that the G1 supports all diving types—recreational, advanced, technical, freediving, and spearfishing—without requiring expensive air integration transmitters. GPS marks your surface entry and exit points, useful when boat diving in unfamiliar locations. The Garmin Dive app provides detailed analysis after your dives, though it’s a separate download from the main Garmin Connect app.

The G1 excels for divers who want one device that handles both diving and daily life. If you’re tired of swapping between a dive computer and a smartwatch, this consolidates everything into a comfortable, capable package. The price point makes it accessible for intermediate divers who don’t need air integration but want more than basic freediving features.
If you require wireless tank pressure monitoring or need advanced gas mixing capabilities, the G1’s lack of air integration will be limiting. Technical divers who need larger displays with more information density may find the compact screen cramped. Also, if you prioritize color displays for readability, the monochrome screen may feel basic compared to newer options.

Simple recreational focus
The Shearwater Peregrine takes the brand’s legendary reliability and simplifies it for recreational divers. After 40 days of testing, including a week-long dive trip with daily dives, I’m convinced this is the best option for divers who want professional-grade performance without technical diving complexity. The 2.2-inch display is enormous compared to most wrist computers, making it effortless to read at a glance underwater.
What stands out about the Peregrine is its intentional simplicity. Shearwater removed technical diving features like trimix and CCR support, focusing instead on what 90% of divers actually need. The result is a computer that’s easier to use while maintaining the algorithm accuracy and build quality that make Shearwater famous. Battery life is outstanding—I got through three days of diving before needing to recharge.

The two-button interface is brilliant in its simplicity. One button accesses your current dive data, the other navigates menus. There’s no deep menu structure to get lost in, and freediving mode is accessible from the surface with just a few button presses. The vibration alerts for depth warnings and surface intervals are strong enough to feel through a wetsuit.
Build quality is excellent, with stainless steel buttons that feel substantial and reliable. The USB wireless charging station is convenient, though some divers prefer user-replaceable batteries for remote dive trips. The customizable screens let you prioritize the data that matters most to you, whether that’s depth, dive time, or surface interval.

The Peregrine is perfect for divers who want professional-grade performance without technical complexity. If you’re doing recreational freediving, spearfishing, or occasional scuba diving, this computer has everything you need and nothing you don’t. The large display and simple interface make it especially suitable for beginners advancing beyond basic computers.
If you need air integration, technical diving capabilities, or advanced gas mixing, the standard Peregrine won’t meet your needs—you’d need to step up to the Teric or Peregrine TX. Also, divers who prioritize GPS tracking or smartwatch features will find this focused dive computer limited in terrestrial functionality.

The Suunto D5 stands out for its style-conscious design, featuring exchangeable straps that let you customize the look for any occasion. I tested this computer for 35 days, appreciating how it transitions from underwater to social settings without looking like dive gear. The color Memory in Pixel display creates a futuristic aesthetic that draws compliments, even if it struggles in bright conditions.
Underwater, the D5 performs adequately as a freediving computer. The dedicated freedive mode tracks depth, dive time, and surface intervals accurately. Vibration alerts work well for depth warnings, though I found the screen visibility challenging in sunny shallow water. Suunto’s algorithm is less conservative than some competitors, meaning you get slightly more bottom time but should be extra cautious about repetitive diving.

The exchangeable straps are genuinely useful—I switched between the silicone strap for diving and textile options for everyday wear. The strap changing mechanism is intuitive and takes just seconds. Air integration with the optional POD transmitter works well, though the additional cost pushes the price into premium territory.
Bluetooth connectivity to the Suunto app is quick and reliable, downloading dive logs within seconds. However, I experienced software crashes when viewing grouped dives, and many customizations require a PC connection rather than the mobile app. The magnetic charging cable feels flimsy, and interestingly, the magnet can deactivate the digital compass, requiring recalibration.

The D5 excels for divers who prioritize aesthetics and want a computer that looks good in social settings. If you appreciate customizing your gear with different straps and enjoy the color screen aesthetic, this computer delivers. It’s particularly suitable for divers who split time between scuba and freediving, as it handles both modes competently.
If you dive frequently in bright conditions or prioritize screen readability above all else, the D5’s dim display will frustrate you. Divers who prefer simple interfaces will find the excessive button presses tedious. Also, if you need maximum battery life for remote dive trips, the D3’s shorter endurance between charges may be limiting.

The Cressi Nepto is a dedicated freediving computer through and through, designed specifically for breath-hold divers rather than trying to be everything for everyone. After 50 days of testing, including focused freediving training sessions, I’ve come to appreciate its specialized features that generic dive computers simply don’t offer. The compact 48mm case sits comfortably on the wrist, and the 35mm high-contrast display is remarkably readable underwater.
What makes the Nepto unique is its Taravana protection algorithm—a safety feature specifically designed for freedivers doing repetitive deep dives. Taravana syndrome is a real concern for freedivers pushing their limits, and having a computer that actively calculates surface recovery time based on your dive profile provides genuine peace of mind. The pulmonary edema prevention function adds another layer of safety for aggressive training sessions.

The user-replaceable battery is a significant advantage for remote dive trips where charging isn’t an option. Unlike many competitors requiring factory service for battery replacement, the Nepto uses a standard battery that you can swap yourself in minutes. Battery life is excellent, stretching across multiple dive trips before needing replacement.
Bloodshift settings for depth training show that Cressi understands freediving physiology. The dual timer functionality lets you track both dive time and surface intervals simultaneously, while multiple alarm options remind you about depth limits, hydration, and interval timing. The logbook provides detailed analysis of your freediving sessions, helping identify patterns in your performance.
The Nepto excels for freedivers focused on depth training and repetitive diving sessions. If you’re pushing your limits with multiple deep dives per day, the Taravana protection and surface recovery calculations provide safety features that generic dive computers lack. The compact form factor and excellent readability make it ideal for serious freediving rather than casual use.
If you split your time between freediving and scuba, or want a computer with smartwatch features, the Nepto’s freediving-specific focus will feel limiting. There’s no scuba mode to speak of, no GPS, and no connectivity beyond basic Bluetooth. Divers who want one device for all diving types should consider a more versatile option.

The Cressi Donatello proves that you don’t need to spend a fortune to get a reliable freediving computer. I tested this entry-level option for 40 days, and while it lacks the advanced features of premium models, it covers the essentials that most recreational freedivers actually need. The single-button interface is refreshingly simple—perfect for divers who want to jump in the water without studying a manual first.
The high-definition display punches above its price class, remaining readable in various conditions despite the modest screen size. I appreciated the automatic water activation, which eliminates the risk of forgetting to switch modes before diving. The audible alarms for depth and time limits are loud enough to hear, though they lack the vibration feedback that premium models offer.

Having both Air and Nitrox modes adds versatility for divers who occasionally dive with scuba equipment. The user-selectable deep stops let you add conservatism if desired, and the ability to switch between imperial and metric units accommodates international dive travel. The user-replaceable CR2430 battery is another cost-saving feature, eliminating the need for factory service.
The optional IR interface for data transfer to computers is a nice touch for divers who want to analyze their dive profiles, though it must be purchased separately. Battery life indicators give you advance warning before the battery dies, preventing surprises during dive trips. Overall, the Donatello delivers solid performance for entry-level divers who prioritize simplicity over advanced features.

The Donatello is ideal for new freedivers who want reliable safety features without investing in a premium computer. If you’re just starting out and unsure how seriously you’ll pursue the sport, this provides essential depth tracking, dive timing, and surface interval monitoring at an accessible price point. The single-button operation reduces complexity during the learning curve.
If you’re doing serious depth training or repetitive freediving sessions, the Donatello’s basic features won’t provide the safety algorithms and detailed tracking that more advanced computers offer. Divers who need data logging capabilities or want to analyze their dive profiles in detail will find the limited connectivity frustrating.

The SEAC Partner occupies the bottom of the price range, making freediving computers accessible to beginners on a tight budget. I tested this computer for 30 days, and while it has significant limitations, it does provide basic depth tracking and dive timing for casual users. The backlit LCD display is easy enough to read, and the simple operation means you can start using it immediately without studying menus.
The most significant limitation is that buttons cannot be operated underwater—you must remember to manually switch to dive mode before entering the water. This design choice makes it less suitable for spontaneous diving and increases the risk of forgetting to activate dive mode. However, for planned training sessions where you’re prepared anyway, this becomes less of an issue.

The factory default depth limit of 40 feet with a 1:20 dive time ratio is quite conservative, which is appropriate for absolute beginners but will frustrate more experienced freedivers. The good news is these limits are adjustable, allowing the computer to grow with your skills. Recording up to 99 dives per session provides ample tracking for a day of training.
Using a standard CR2032 battery keeps long-term costs down, and the lightweight design means you’ll barely notice it on your wrist. Some scuba divers use the Partner as a backup depth gauge, though this isn’t its intended purpose. The 100m water resistance rating provides confidence for recreational freediving depths.
The Partner is suitable for beginners who want to try freediving without investing in expensive equipment. If you’re unsure whether you’ll stick with the sport, this provides basic safety features at minimal cost. It’s also useful as a backup computer for more experienced divers who want redundancy during deep dives.
If you’re committed to freediving and plan to push your limits, the Partner’s limitations will quickly become frustrating. The inability to operate buttons underwater, lack of advanced safety algorithms, and reported quality concerns make it unsuitable as a primary computer for serious divers. Budget permitting, stepping up to the Cressi Donatello provides significantly better value.
Choosing the right freediving computer involves understanding how these devices differ from scuba dive computers and which features matter most for breath-hold diving. This guide breaks down the essential considerations to help you make an informed decision based on your diving style, experience level, and budget.
While many computers handle both scuba and freediving, dedicated freediving computers optimize specifically for breath-hold diving. The key difference lies in the algorithms—freediving computers calculate surface intervals and repetitive dive limits based on the unique physiology of apnea diving, where your body undergoes repeated compression and decompression cycles without breathing compressed gas.
Scuba computers focus on nitrogen absorption from breathing pressurized air underwater, tracking no-decompression limits for a completely different physiological process. While you can use a scuba computer in freedive mode, dedicated freediving computers like the Cressi Nepto offer specialized features such as Taravana protection that generic dive computers lack.
Another important difference is display priority. Freediving computers emphasize depth, dive time, and surface interval on the main screen, while scuba computers prioritize no-decompression limits and gas switching. For breath-hold diving, you want information readable at a glance during the brief surface intervals between dives.
Display visibility tops the list of essential features. You need a screen readable in various lighting conditions, from bright surface sunlight to murky depths at 100 feet. The Shearwater Peregrine and Teric excel here with large, bright displays that remain clear in challenging conditions. Backlight quality matters too—some computers have backlights that are too dim or shut off too quickly.
Surface interval tracking is critical for safety. The best freediving computers display your surface time prominently, calculating how long you need to recover before your next dive based on your previous profile. This prevents shallow water blackout from insufficient surface recovery between repetitive dives.
Depth alarms provide an important safety net, alerting you when you exceed predetermined limits. Look for computers with both visual and audible alerts, though vibration alerts like those on the Shearwater models are most reliable underwater. Multiple depth alarm settings let you set different limits for training versus recreational diving.
Battery type significantly impacts long-term ownership costs and convenience. User-replaceable batteries like those in the Cressi Donatello and SEAC Partner eliminate the need for factory service and allow you to carry spares for remote dive trips. Rechargeable batteries like those in the Garmin and Shearwater models reduce ongoing costs but require charging access between dive trips.
Battery life varies dramatically between models. Smartwatch-style computers like the Garmin Descent G1 offer weeks of battery life in everyday mode but drain faster during dive days. Dedicated dive computers like the Shearwater Peregrine prioritize dive-time battery life, stretching across multiple days of diving before needing recharge.
Display technology affects readability more than any other factor. Color LCD displays like the Shearwater Teric offer excellent contrast and customization options. AMOLED displays like the Garmin Descent Mk3i provide vibrant colors and deep blacks but at a higher price point. Monochrome displays like the Garmin Descent G1 sacrifice aesthetics for battery efficiency but remain perfectly readable underwater.
Screen size matters more than resolution underwater. The Shearwater Peregrine’s 2.2-inch display is significantly easier to read than compact 0.9-inch displays, regardless of resolution. Consider your eyesight and typical diving conditions—larger displays help in murky water or low light.
Budget computers under $300 like the Cressi Donatello and SEAC Partner cover essential freediving functions but lack advanced features. They’re suitable for beginners and casual divers but may limit your progression as you advance.
Mid-range options from $300-600 like the Garmin Descent G1 and Shearwater Peregrine offer the best value for most divers. You get excellent freediving functionality, good displays, and enough features to grow into without paying for capabilities you’ll never use.
Premium models above $600 like the Garmin Descent Mk3i and Shearwater Teric deliver professional-grade performance with air integration, advanced algorithms, and often smartwatch functionality. These investments make sense for serious divers who spend significant time underwater and want the best safety tools available.
The best dive computer for beginners balances simplicity with essential safety features. The Cressi Donatello offers single-button operation and an intuitive interface perfect for those new to diving. It covers freediving, air, and Nitrox modes, providing room to grow as you advance.

Yes, most modern scuba dive computers include freedive or apnea mode specifically for breath-hold diving. However, dedicated freediving computers like the Cressi Nepto offer specialized features that generic dive computers lack. The key difference is in the algorithms—freediving computers calculate surface intervals based on the unique physiology of repeated breath-hold dives, while scuba computers focus on nitrogen absorption from compressed gas. For occasional freediving, a scuba computer with apnea mode works fine. For serious freediving training, a dedicated computer provides better safety features like Taravana protection and surface recovery calculations.
Essential freediving computer features include: display visibility in various conditions, prominent surface interval tracking, depth alarms, and dive log memory. The display must remain readable underwater, from bright surface sunlight to murky depths. Surface interval tracking calculates recovery time between dives, preventing shallow water blackout. Depth alarms alert you when exceeding predetermined limits. Advanced features to consider include vibration alerts more reliable than audible alarms underwater, customizable screens to prioritize your preferred data, Taravana protection for repetitive deep diving, and user-replaceable batteries for remote dive trips. Smartwatch integration matters if you want everyday functionality, while air integration appeals to divers who also scuba dive.
A good freediving computer typically costs between $300-600 for most recreational divers. Budget options under $300 like the Cressi Donatello cover essential functions but may limit progression as you advance. Mid-range computers like the Garmin Descent G1 and Shearwater Peregrine offer the best value, combining excellent freediving features with build quality that lasts.
