Top 3 Picks for Best Freediving Dive Computers

Best Freediving Dive Computers in 2026

1. Shearwater Peregrine Adventures Edition – Best Overall Display

I have used the Shearwater Peregrine on multiple freediving trips over the past year, and the first thing that stands out is that screen. The 2.2-inch LCD display with 320×240 resolution is sharp, bright, and readable at any depth. Unlike some cheaper computers where you find yourself squinting at small digits, the Peregrine displays depth, dive time, and surface interval in large, clearly separated fields. Even in murky water at 30 meters, I had zero trouble reading my data at a glance.

The two-button interface with state-aware menu structure makes navigation intuitive. You press the same button and it knows what options to show based on where you are. The 316 stainless steel buttons feel solid and responsive even with thick freediving gloves on. After using single-button computers where cycling through menus feels tedious, this setup is a breath of fresh air.

Battery life is another area where the Peregrine shines. Shearwater rates it at 30 hours on medium brightness, and in my experience that estimate is accurate. The wireless USB charging station is convenient and the rechargeable lithium-ion battery means no more hunting for replacement coin cells. Bluetooth connectivity lets you sync dive logs to the Shearwater app, which works smoothly on both iOS and Android.

Who Should Buy the Shearwater Peregrine

Freedivers who want the best display readability and user experience should look here first. The Peregrine works well for recreational freedivers, spearfishers, and anyone transitioning from scuba to freediving who still wants a versatile computer. The freedive mode tracks depth, time, and surface intervals accurately, with vibration alerts that are hard to miss even without looking at the screen.

Who Should Skip It

If you need air integration for scuba diving or a digital compass for navigation, the Peregrine does not have these features. Dedicated technical freedivers chasing extreme depths might also want to consider the Shearwater Perdix or Teric instead. The display surface is also prone to scratching, so a screen protector is essential.

2. Cressi Donatello – Best Value Multi-Mode Computer

The Cressi Donatello sits in a sweet spot for divers who want a reliable computer that handles multiple dive modes without paying premium prices. With 587 reviews and a 4.3-star rating, it has earned its reputation as a solid all-around performer. The HD backlit display provides clear visibility underwater, and the single-button interface keeps operation straightforward, which is exactly what you want when your mind is focused on your breath-hold.

For freediving specifically, the Donatello operates in gauge mode, tracking depth, dive time, and surface interval. It also handles air and nitrox modes for scuba diving, making it a versatile choice for divers who do both. The replaceable CR2430 battery is easy to swap, so you never have to worry about running out of charge mid-trip. Just carry a spare battery and you are set.

One thing I appreciate about the Donatello is the user-selectable deep stops feature. While this is more relevant for scuba, it shows the thought Cressi put into making this computer versatile. The imperial and metric unit options make it suitable for divers worldwide. At 129 grams, it is comfortable on the wrist for long sessions.

Who Should Buy the Cressi Donatello

Divers who split time between freediving and scuba will get the most value here. The multi-mode capability means one computer handles everything. It is also a strong choice for intermediate freedivers who want clear data display and reliable performance without spending on premium features they may not need.

Who Should Skip It

Pure freedivers who never plan to scuba dive might find the gauge mode limiting compared to dedicated freediving computers like the Cressi Nepto. Some users have reported bezel leakage after extended use, so if you dive frequently in harsh saltwater conditions, you may want to inspect the seals regularly.

3. Salvimar One Plus – Best Budget Freediving Watch

The Salvimar One Plus is purpose-built for freediving and spearfishing, and that focus shows. At just 64 grams, it is one of the lightest computers in this roundup, barely noticeable on your wrist during long sessions. The automatic activation when submerged is a feature I really value because you never forget to start tracking your dive. The moment you hit the water, it begins recording.

Depth tracking goes up to 100 meters, which covers the vast majority of freediving and spearfishing scenarios. The real-time data includes dive time, surface interval, and water temperature, which are the three metrics most freedivers care about most. The EL backlight provides adequate visibility in low-light conditions, though it is not as bright as the Shearwater Peregrine display.

What makes the Salvimar One Plus stand out at this price point is the surface recovery tracking. The computer monitors your surface interval and helps you determine when it is safe to dive again. This is a critical safety feature that many budget freediving watches omit. The recovery time algorithm takes into account your depth and bottom time from previous dives.

Who Should Buy the Salvimar One Plus

Budget-conscious freedivers and spearfishers who want a lightweight, purpose-built freediving computer will find excellent value here. It is also ideal for beginners who are not ready to invest heavily but still want proper depth and time tracking. Forum users on r/freediving frequently recommend this as a starter computer.

Who Should Skip It

If you need a computer that also handles scuba diving, the One Plus is not designed for that. The small display digits can be difficult to read for divers with vision issues. Some users have also reported the bracelet breaking after about a year of heavy use, so consider replacing the strap with something more durable if you dive frequently.

4. Cressi Leonardo 2.0 – Best for Beginners

The Cressi Leonardo 2.0 has been one of the most popular entry-level dive computers for years, and with over 3,500 reviews backing it, the community has spoken. I recommended this to a friend who was just starting freediving, and within two sessions she was completely comfortable reading depth, time, and surface interval data without any confusion. The large display makes data visible at a glance, which is exactly what a beginner needs.

Operating the Leonardo is about as simple as it gets. One button does everything. Short press, long press, and the computer cycles through menus and settings accordingly. While this can feel tedious when you are configuring settings initially, once set up, the simplicity is a real advantage underwater. No accidentally hitting the wrong button during a dive.

The gauge mode is what most freedivers use on the Leonardo, and it provides accurate depth, dive time, and temperature readings. The three user-adjustable conservatism levels let you dial in how conservative the decompression algorithm behaves, which is useful for divers transitioning between freediving and shallow scuba. The CR2430 battery is user-replaceable and lasts a long time between changes.

Who Should Buy the Cressi Leonardo 2.0

Beginner freedivers who want a proven, reliable computer with a massive user base and extensive community knowledge will feel right at home. The loud audible alarms are useful for training sessions where you want depth or time reminders. It is also a solid backup computer for experienced divers who want something simple and dependable.

Who Should Skip It

The Leonardo is bulky at 200 grams and is not something you would wear as an everyday watch. Freedivers who want Bluetooth connectivity and app integration should look elsewhere, as the Leonardo requires a separate USB IR interface for data transfer. The conservative decompression limits can also frustrate experienced divers doing multi-dive days.

5. Mares Puck Pro Ultra – Best Display Contrast

The Mares Puck Pro Ultra is a recent addition to the Mares lineup, and it brings some impressive specs for the price. The Buhlmann ZH-L16C decompression algorithm with dual gradient factors is a feature typically found on more expensive computers. For freedivers who also do technical scuba diving, having this level of algorithmic sophistication in one device is a real advantage.

The high-contrast screen is the standout feature. Mares designed this display specifically for readability in varying light conditions, and it delivers. During pool training sessions and open water dives, the data stands out clearly against the background. The one-button navigation keeps things simple, though like all single-button systems, initial setup takes patience.

Battery life is rated at up to 100 dives per CR2450 battery, which is generous. The Bluetooth connectivity syncs with the Mares app for dive log tracking, which worked smoothly during my testing. The app displays your dive profiles, temperature data, and depth graphs in a clean, organized interface.

Who Should Buy the Mares Puck Pro Ultra

Freedivers who also do recreational or technical scuba diving will appreciate the advanced algorithm and multi-gas Nitrox support. The high-contrast display makes it a great choice for divers who frequently dive in varying visibility conditions. Strong initial 4.7-star rating suggests Mares got the formula right with this model.

Who Should Skip It

With only 13 reviews so far, this is a relatively unproven product. If you prefer buying gear with an established track record, you might want to wait for more user feedback. The wrist band quality is noticeably lower than the rest of the build, so factor in a strap upgrade if you plan to use this heavily.

6. Cressi Nepto – Best Dedicated Freediving Computer

The Cressi Nepto is one of the few computers designed specifically for freediving from the ground up, and it shows in every detail. The Taravana protection algorithm is the headline feature. Taravana syndrome is a serious decompression condition that can affect freedivers doing many repeated deep dives, and the Nepto actively monitors your dive profiles to warn you when surface intervals are insufficient. This safety feature alone makes it worth considering for serious freedivers.

Beyond taravana protection, the Nepto also includes pulmonary edema risk prevention. This addresses another serious health concern for deep freedivers. Having both safety systems in one compact watch is something no other computer at this price point offers. The 48mm case with 35mm high-contrast LCD display strikes a good balance between readability and wrist comfort.

Build quality is excellent. The mineral glass display resists scratches better than most, and the heavy-duty case with stainless steel buttons feels like it will last for years. Made in Italy by a company with decades of diving equipment experience, the Nepto has the fit and finish of a premium product. At 100 grams, it is comfortable for all-day wear, both in and out of the water.

Who Should Buy the Cressi Nepto

Serious freedivers and freediving instructors who prioritize safety features above all else should put the Nepto at the top of their list. The taravana and pulmonary edema protection algorithms are genuinely life-saving features for divers doing multiple deep dives in a session. It is also compact enough to wear as an everyday watch.

Who Should Skip It

The Nepto is freediving-only, so divers who also scuba will need a separate computer. The lack of GPS and the basic Cressi app experience might disappoint tech-savvy users. Connecting to your phone requires purchasing a separate interface, which adds to the total cost. The non-rechargeable battery means eventual replacement is needed.

7. SEAC Partner – Best Entry-Level Freediving Computer

The SEAC Partner is one of the most affordable dedicated freediving computers you can buy, and for the price, it delivers the essentials well. It records up to 99 dives per session, tracks depth and dive time, and includes a stopwatch and countdown function for training. The backlit display is readable in most conditions, though it is not as crisp as higher-end models.

One feature I appreciate is the standard CR2032 battery. These are available at any drugstore, so you never have to worry about proprietary charging cables or being stuck with a dead computer on a dive trip. The battery lasts a long time for typical freediving use, and data is retained between battery changes.

The 100-meter water resistance covers most freediving scenarios, and the wrist-mounted design is comfortable for extended sessions. SEAC designed this as a straightforward freediving tool, and they succeeded at that goal. It does what it needs to do without unnecessary complexity.

Who Should Buy the SEAC Partner

First-time freedivers who want a dedicated freediving computer at the lowest possible price will find the SEAC Partner hard to beat. It is also a good backup computer to keep in your dive bag. The simple operation means you can hand it to a buddy who has never used a dive computer and they will figure it out quickly.

Who Should Skip It

The instructions that come with the SEAC Partner are notoriously unhelpful. Plan to spend time on forums or YouTube learning the settings. The factory defaults for maximum depth and time need adjustment before your first dive. Experienced freedivers who want advanced features like taravana protection or Bluetooth connectivity should step up to a higher model.

8. Cressi Neon – Best Versatile 4-Mode Computer

The Cressi Neon packs four dive modes into a sleek 48mm package, making it one of the most versatile computers in this roundup. Air, Nitrox, Freediving, and Gauge modes cover virtually every type of diving you might do. The dedicated freediving mode tracks depth, dive time, and surface interval with the same accuracy as computers costing significantly more.

The Cressi RGBM Wienke 9-tissue decompression algorithm is a proven system that Cressi has refined over years. For freediving, the algorithm focuses on tracking your repetitive dive profiles and calculating appropriate surface intervals. The high-intensity backlight rated at 4000 Mlux is one of the brightest in this class, making night diving and low-visibility conditions much more manageable.

The two-button navigation system is a meaningful upgrade over single-button computers. Being able to scroll forward and backward through menus saves time and frustration. The logbook stores 50 dives or 40 hours of data, which is adequate for most recreational divers. The user-replaceable battery has an estimated life of 4 years at 50 dives per year.

Who Should Buy the Cressi Neon

Divers who want one computer that genuinely handles both freediving and scuba with equal competence will find the Neon compelling. The four modes make it versatile enough for divers who explore different types of diving. Italian manufacturing quality is apparent in the build and materials.

Who Should Skip It

Some users have reported water ingress issues, which is concerning for a dive computer. If you plan to sync dive data to your phone, the separate Bluetooth interface adds extra cost. With only 36 reviews, the long-term reliability picture is still developing. Consider the Cressi Donatello if you want a similar experience with a larger review base.

9. SEAC Apnea – Best Safety-Focused Freediving Computer

The SEAC Apnea puts safety front and center with its MSST function, which stands for Minimum Suggested Surface Time. This feature calculates how long you should wait on the surface before your next dive based on your previous depth and bottom time. For freedivers who tend to push their limits, having this information displayed clearly on the wrist can prevent dangerous situations.

The display shows dive data and ascent speeds, total dive time, and depth all on a single screen. This is a real advantage over computers that require you to scroll through screens to see different data points. The LCD screen has adjustable contrast and backlighting intensity, so you can tune it to your preferences and conditions. The USB cable included in the box allows PC connection for downloading dive logs, which is a nice inclusion at this price.

Sound and visual alarms can be deactivated if you prefer a distraction-free dive. The adjustable backlighting intensity is a thoughtful touch that lets you conserve battery during daytime dives while cranking up the brightness for night sessions. At 0.27 kilograms, it has a bit more heft than some options, but the larger size also means larger, easier-to-read digits.

Who Should Buy the SEAC Apnea

Freedivers who prioritize safety features and want a computer that actively helps prevent dangerous situations will find the MSST function invaluable. The single-screen data display is perfect for divers who want all key information visible at once. The included USB cable for PC sync is a nice value-add that competitors often charge extra for.

Who Should Skip It

Quality control seems inconsistent based on user reviews. Some units have had issues with buttons not working properly or condensation forming inside the display. The instructions included in the box are incomplete, so you will likely need to find additional resources online. Only one programmable depth alarm limits customization for training sessions.

10. Aqualung i100 – Best Backup Freediving Computer

The Aqualung i100 is a straightforward dive computer that covers the basics across four modes: Air, Nitrox, Gauge, and Free Dive. The dedicated Free Dive mode is what makes it relevant for our roundup. It tracks depth, dive time, and surface interval in a simple, no-frills interface that is easy to understand even on your first dive.

What I like about the i100 is the user-changeable battery with data retention. When you swap the battery, your settings and dive logs are preserved. The one-button navigation keeps operation simple, and the big numbers on the display are easy to read underwater. The salt or fresh water selection is a practical feature that affects depth accuracy, and it is something many budget computers overlook.

At 11.2 ounces, the i100 has some weight to it, but the form factor is manageable. The ability to handle 2 Nitrox gases up to 100% and change them underwater makes it useful for scuba divers as well. As a backup computer for freediving trips, the i100 provides the core data you need without unnecessary complexity or expense.

Who Should Buy the Aqualung i100

Divers who want an affordable backup computer that handles both freediving and scuba will find the i100 a practical choice. The four modes and user-changeable battery make it a reliable safety net. Beginners on a tight budget who want basic freediving tracking without premium features will also find it sufficient.

Who Should Skip It

The absence of a backlight is a significant limitation for low-light diving. No Bluetooth or included download cable means getting your dive data off the device requires additional purchases. Some users have reported quality control issues, including settings getting stuck. At 3.8 stars, it has the lowest rating in our roundup, so consider the SEAC Partner or Salvimar One Plus for better budget alternatives.

How to Choose the Best Freediving Dive Computer

Picking the right freediving computer comes down to understanding what features matter for your specific type of diving. Not every diver needs the same thing, and overspending on features you will never use is a common mistake I see in freediving forums. Here is what to focus on.

Dedicated Freediving Mode vs Gauge Mode

This is the most important distinction to understand. A dedicated freediving mode, found on computers like the Cressi Nepto and SEAC Apnea, is specifically designed for breath-hold diving. It tracks repetitive dives, calculates surface intervals, and often includes safety features like taravana protection. Gauge mode, found on computers like the Cressi Leonardo, simply tracks depth and time without the freediving-specific calculations. If freediving is your primary activity, a dedicated freediving mode is worth seeking out.

Depth Rating

Most freediving computers are rated to 100 or 120 meters. For recreational freedivers and spearfishers who rarely go below 40 meters, 100 meters is more than sufficient. Competitive freedivers training for depth records should look at 120-meter rated computers like the Shearwater Peregrine or Cressi Nepto for that extra margin.

Display Readability

You will be reading this computer underwater, often in low visibility or while holding your breath. Large digits, high-contrast displays, and bright backlights matter more than you might think. The Shearwater Peregrine leads the pack here with its 320×240 LCD, but the Mares Puck Pro Ultra and Cressi Neon also offer excellent display quality.

Battery Life and Charging

Rechargeable batteries, like on the Shearwater Peregrine, are convenient and eliminate the need to carry spare coin cells on trips. However, user-replaceable batteries found on most Cressi and SEAC models mean you can swap in a fresh battery in minutes and keep diving. For extended freediving trips where charging might not be available, a replaceable battery computer offers peace of mind.

Safety Features

Serious freedivers should prioritize safety algorithms. The Cressi Nepto offers taravana protection and pulmonary edema prevention, which are specifically designed for the risks freedivers face. The SEAC Apnea includes MSST, which calculates minimum surface time between dives. These features go beyond basic depth and time tracking to actively protect your health during repetitive freediving sessions.

Size and Comfort

If you plan to wear your computer for hours during a freediving session, weight and comfort matter. The Salvimar One Plus at 64 grams is the lightest option in our roundup, while the Cressi Leonardo at 200 grams is noticeably heavier. Dedicated freediving watches like the Cressi Nepto and SEAC Partner strike a good balance between readability and all-day comfort.
