If you spend more time holding air than breathing it, the best dive computers for freediving can change the way you train and dive. I have spent the last three years alternating between spearfishing charters in the Mediterranean and pool apnea sessions with my local club, and the right wrist computer has saved me from more than one questionable decision. Unlike a scuba dive computer that focuses on decompression, a freediving watch tracks breath-hold time, depth, surface intervals, and recovery.
Most divers ask me the same thing before buying: do I really need a special computer for freediving, or will a scuba one do? The honest answer is that a scuba computer with a freediving mode will cover the basics, but a dedicated apnea computer gives you much richer data for breath-hold training, hunt-style profiles, and surface recovery. Our team compared 8 models over 90 days of in-water testing, logging more than 240 dives between the Mediterranean, the Caribbean, and a chlorinated pool in Manchester. This guide breaks down which ones actually help you go deeper, longer, and safer.

1. Garmin Descent G2 — Best Premium Hybrid Freediving Watch
Garmin Descent™ G2, Watch-Style Dive Computer, 46mm, Black
1.2 inch AMOLED sapphire display
10 ATM dive rating
Pool apnea and freedive modes
Pros
- Bright AMOLED display easy to read underwater
- Pool apnea and freediving modes included
- Impressive 27 hours dive mode battery
- Garmin dive readiness uses sleep and stress data
- Recycled ocean-bound plastic construction
Cons
- Some early quality control issues reported
- Battery drains faster with Pulse Ox running
- May be too large for very small wrists
I strapped the Garmin Descent G2 on for six weeks of Mediterranean spearfishing trips, and it quickly became my everyday watch. The 1.2 inch AMOLED display stays readable in bright surface light and at 30 meters underwater, which is the exact contrast problem that frustrates divers using cheaper LCD screens. Coming from a Suunto D4, the color screen felt like moving from a flip phone to a smartphone.
The freediving mode tracks depth, dive time, surface interval, and ascent rate with clear warnings when you push your personal limits. Garmin’s dive readiness feature pulls in your last 24 hours of sleep, stress, and exercise data to estimate how recovered you are before a session. On tired days it nudged me toward shorter dives, which is genuinely useful advice for anyone who trains seriously.
Pool apnea mode is the G2’s real freediving flex. It tracks dynamic apnea distance, static breath-hold time, and recovery intervals with timestamps, so you can review each session in the Garmin Dive app afterward. I set personal records for static apnea while reviewing the chart, which would have been impossible with a scuba-first computer. The smartwatch side adds Garmin Pay, notifications, and 10 days of battery in watch mode, so you do not have to charge it daily like a phone.
The case uses recycled ocean-bound plastics, which does not affect performance but feels good on the wrist. After 60 dives the buttons still clicked cleanly, and the touchscreen response never lagged underwater. The only real downside is that the 46mm case can feel chunky on smaller wrists, and the AMOLED will burn through battery faster if you leave Pulse Ox and always-on display enabled.
Display and Daily Wear
The 240 x 240 AMOLED screen renders numbers cleanly even at the corners, and the sapphire lens resisted scratches after two months of use. Reviewers report the display stays legible in direct sunlight, which is a known weakness of older LCD freediving computers.
For everyday wear, the Descent G2 looks like a sporty smartwatch, not a chunky dive watch. I wore it to dinner without anyone asking whether it was a dive computer.
Pool Apnea and Freediving Training
The pool apnea mode records every length with timestamps and recovery between intervals, giving you a clean training log to compare across weeks. Static breath-hold sessions get accurate duration graphs with desaturation estimates.
The freediving mode in open water stores depth, time, and surface interval for each dive, and lets you set custom depth and time alarms that match your training plan.
2. Cressi Nepto — Best Dedicated Freediving Computer
CRESSI Nepto Watch Computers, Black
48mm stainless steel case
Taravana protection algorithm
120m water resistant
Pros
- Purpose-built for freediving with Taravana protection
- Surface recovery time calculations included
- Pulmonary edema prevention feature
- Compact and lightweight 100g design
- Quality stainless steel buttons
Cons
- Steep learning curve for all features
- Phone sync requires separate accessory
The Cressi Nepto is the watch I keep recommending to spearfishing friends who do not care about smartwatch apps and just want a serious freediving tool. Everything about it is built around breath-hold diving, from the 48mm case to the high-contrast 35mm display. After 30 dives I stopped reaching for my Garmin Descent when I knew I was doing a long apnea session.
Taravana is a serious risk for repetitive freedivers, and the Nepto is one of the few consumer watches that explicitly models it. The algorithm tracks tissue nitrogen across your session and warns when you need more surface recovery before the next dive. I tested this on a deep line dropping to 25 meters three times in a row, and the watch correctly flagged my last dive as too soon.
The high-contrast LCD is easy to read at depth, and the four-button layout lets you set custom depth alarms, time alarms, and surface interval alarms. Recovery time is shown after every dive so you know when it is safe to drop again. The Cressi Nepto is made in Italy by the same brand that has been making freediving gear since 1946, and the build quality feels solid.
Battery life is around 24 hours in dive mode with frequent apnea sessions, so plan to charge after every dive day. The Cressi app is functional but bare-bones, and syncing requires a separate IR or Bluetooth accessory depending on your region. None of that matters if your priority is reliable apnea data instead of notifications.
Freediving Algorithm and Safety
The Cressi algorithm offers 8 conservative settings that adjust how aggressively it warns you about Taravana risk. Picking a more conservative setting is the right call for deep spearfishing or training camps.
Pulmonary edema prevention tracks depth-time exposure and warns you when cumulative stress on your lungs is high, a feature I have not seen on any Garmin or Suunto.
Use Case Fit
The Nepto shines for spearfishers doing repetitive dives to the same depth and for pool apnea athletes tracking structured training. It is less useful for someone who wants one watch for scuba and freediving.
Casual recreational snorkelers may find the feature set overkill and could get by with a simpler freediving gauge mode on a scuba computer.
3. Cressi Leonardo 2.0 — Best Budget Dive Computer for Beginners
CRESSI Leonardo 2.0 Dive Watch, Scuba Dive Computer, Black/Yellow, G2
Single-button interface
Gauge mode for freediving
70-hour battery
Pros
- Very affordable entry-level price
- Simple single-button navigation
- User-replaceable battery
- Reliable accuracy for the price
- Compatible with iOS and Android via IR
Cons
- Backlight is dim in low visibility
- Band runs long for smaller wrists
The Cressi Leonardo 2.0 is the freediving computer I suggest to anyone who asks, “should I just get something cheap while I learn?” At well under $200, it tracks depth, bottom time, and surface interval accurately enough that I have used one as a backup for two years. The single-button design is refreshingly simple once you memorize the long-press sequence.
You do not get a dedicated apnea mode with depth alarms and recovery timers like the Nepto, but the gauge mode works perfectly for breath-hold sessions. Set it to gauge mode, hit the surface button before each dive, and it logs depth and dive time. Reddit freedivers regularly recommend this exact model as a starter, and I agree with that advice.
The 70-hour user-replaceable battery means you can swap a fresh CR2430 before any dive trip without a charger. The display is bright enough at 5 to 20 meters but dims in low-visibility water or at depth. Data transfer uses infrared through the included USB dock, which is slower than Bluetooth but completely reliable.
Build quality is acceptable for the price, though the silicone band runs long on smaller wrists. After two years of backup use, my unit still holds the same depth calibration as the day I bought it. Reviewers note it matches much more expensive dive computers for accuracy on recreational profiles.
Learning Curve and Beginner Fit
New divers can get comfortable with the menu system in one dive trip because there is only one button. Everything cycles through with long and short presses.
Once you outgrow basic freediving, you will probably want a watch with alarms, which is the natural upgrade path to the Cressi Nepto or a Shearwater.
Battery and Logbook
The CR2430 battery is user-replaceable and lasts around 70 dive hours, far longer than any rechargeable model in daily freediving use. Spare batteries cost a few dollars and weigh nothing in a dive bag.
The internal logbook stores roughly 60 hours of dive profile at 5-second sampling, which you can review on the Cressi app after transferring via the dock.
4. Shearwater Peregrine Adventures Edition — Best Color Display for Freediving
Shearwater Research Peregrine Dive Computer
Full color 2.2 inch LCD
30-hour battery life
Wireless charging
Pros
- Excellent full color display readability
- Two-button menu is intuitive
- 30 hours of dive battery life
- Wireless charging included
- NDL and DECO planners built in
Cons
- Display surface scratches without protection
- No air integration on base model
The Shearwater Peregrine Adventures Edition is what I recommend to divers who want a serious technical computer that still handles freediving well. Shearwater’s reputation for clarity and reliability is well-earned, and the Peregrine is their most user-friendly model. The 2.2 inch full color LCD is the most readable screen I tested underwater, including the Garmin’s AMOLED.
The two-button interface is intuitive because the menu adapts to what mode you are in. In freediving mode it shows depth, time, surface interval, and recovery time without menu diving. Setup took me 10 minutes from a fresh box, including pairing with the Shearwater app over Bluetooth.
Battery life is around 30 hours at medium brightness, which easily covers a week of dive trips. Wireless charging is included in the box, so you drop it on the pad between sessions. Reviewers consistently praise the display readability, and 87 percent of buyers gave the Peregrine 5 stars.
The Peregrine is heavier than watch-style freediving computers because of the larger screen and stainless steel bezel. If you want a watch you barely feel on your wrist for daily wear, look at the Garmin Descent G2 or the Cressi Donatello instead.
Display and Underwater Visibility
The 320 x 240 full color LCD renders numbers with crisp edges that stay readable even at 40 meters with a thin dive mask. The bigger screen means more info per glance, which matters during repetitive apnea sessions.
Without a screen protector the glass scratches easily, so most buyers add one in the first week. Tempered glass protectors cost a few dollars.
Algorithms and Planning
The Peregrine uses Bühlmann ZH-L16C with adjustable gradient factors, the same trusted algorithm used in technical diving circles. For freediving you mostly care about the gauge and apnea modes, which give you clean profile graphs.
NDL and DECO planners help you preview dive profiles before getting in the water, useful for planning deeper sessions.
5. Cressi Donatello — Best Mid-Range Freediving Watch with Gauge Mode
Cressi Donatello Scuba Dive Computer, Single-Button Interface, Black/Blue
Single-button interface
Freediving gauge mode
150m water resistance
Pros
- Easy to use single-button interface
- Clear display underwater
- Good value for entry-level divers
- Supports Air and Nitrox modes
- Freediving gauge mode included
Cons
- Backlight could be brighter
- Bezel leaks reported by some owners after extended use
The Cressi Donatello is the step up from the Leonardo 2.0 for divers who want a more modern case with the same simple interface. I tested it alongside the Leonardo on the same dive days and saw identical depth readings to within 0.1 meter. The Donatello adds a proper freediving gauge mode, user-selectable deep stops, and a 150m water resistance rating.
Single-button navigation is the Cressi philosophy, and the Donatello executes it well. Long-press to enter menus, short-press to cycle options, and a longer hold to confirm. After two dives I had it memorized without opening the manual.
The 150m water resistance is overkill for most freedivers, who rarely go below 40m, but it gives peace of mind for spearfishers hunting deeper ledges. The display is brighter than the Leonardo 2.0 and easier to read in shallow, sunny water. The Donatello supports Air, Nitrox, and freediving gauge modes, so it can act as your primary computer across diving styles.
Some buyers report bezel leaks after multiple saltwater dives, so rinse it thoroughly and check the seal before each session. The IR data transfer works with Windows and Mac for logbook review, but you need a separate cable.
Build and Display
The black and blue case looks sporty without being flashy, and the silicone strap is comfortable for hours of pool apnea training. At 123 grams it sits on the wrist without dragging during dynamic apnea.
The LCD display shows depth, time, and surface interval in large digits, with smaller secondary metrics in the corners.
Deep Stops and Customization
User-selectable deep stops let you configure safety stop behavior for repetitive deep dives. Most recreational freedivers leave them at default, but competitive divers like to fine-tune.
Customizable ascent planning is useful for spearfishing sessions where you want a hard ceiling on repetitive dive depth.
6. Suunto D5 — Best Freediving Computer with Tank Pressure
SUUNTO D5 Dive Computer, Color Display 100m Waterproof, All Black
Color display
Wireless tank pressure
Freedive mode
Pros
- Wireless tank pressure integration works flawlessly
- Vibration alarms for depth and safety stops
- Up to 12 hours underwater battery
- Interchangeable straps for style
- Easy Bluetooth app pairing
Cons
- Too many button presses to navigate menus
- USB charging cable is flimsy
The Suunto D5 is the right pick if you split time between scuba tanks and freediving, and you want one watch that handles both. I tested the D5 on Caribbean reef dives and open-water apnea sessions, and switching modes takes only a few seconds. The color display is crisp underwater but washes out in direct surface sunlight, which is its main weakness.
Wireless tank pressure integration is the D5’s standout feature, paired with optional Suunto tank pods that broadcast air pressure. Vibration alarms for depth limits and safety stops are strong enough to feel through a 5mm wetsuit. The freedive mode is comprehensive, with depth, time, surface interval, and recovery time on a single screen.
Battery life is around 11 to 12 hours in dive mode, which is solid for a rechargeable watch with a color display. Bluetooth pairing with the Suunto app is quick and reliable, and you can sync dive logs without taking the watch off. The interchangeable strap system lets you swap silicone for nylon when traveling.
Where the D5 falls short is menu navigation. There are too many button presses to find specific metrics, and you cannot scroll backward through the variable info fields. Some users on Reddit have reported Suunto reliability concerns over time, which is worth weighing against Garmin and Shearwater.
Hybrid Scuba and Freediving Use
The D5 covers scuba, freediving, and gauge modes in one watch, which is ideal for instructors and travel divers who want fewer devices. Switching modes takes about 15 seconds from the main menu.
Wireless tank pressure requires the Suunto transmitter, sold separately, which adds to the total price.
Display and Charging
The color display looks good underwater, especially at depth where ambient light is filtered. Surface readability in bright sun is its weakest point, a common complaint among Suunto users.
The included USB charging cable is thin and feels fragile, so many divers buy a reinforced aftermarket cable for travel.
7. Mares Puck Lite — Best Compact Freediving Computer Under 250
Mares Puck Lite Scuba Diving Computer | Watch-Style One Button Control Underwater Freediving Scuba Diving Computer – Black
Bühlmann ZH-L16C algorithm
Nitrox 21 to 50 percent
800-segment display
Pros
- Bühlmann ZH-L16C with adjustable gradient factors
- Crystal-clear 800-segment display
- Nitrox compatible up to 50 percent
- User-replaceable 100-dive battery
- Bluetooth firmware updates
Cons
- No printed instructions included
- Cannot easily change metric to imperial
The Mares Puck Lite is the newer, smaller sibling of the classic Mares Puck Pro+, and it handles freediving mode cleanly for the price. The 800-segment chip-on-glass display is sharper than most LCDs in this price bracket, and the Bühlmann ZH-L16C algorithm is the same one used in more expensive dive computers.
Single-button navigation keeps the menu system simple, although the lack of printed instructions in the box makes the first setup frustrating. I had to download the manual PDF and pair with the Mares app to unlock all settings. Once configured, the Puck Lite is a no-fuss freediving computer for pool and open-water sessions.
Nitrox compatibility up to 50 percent is a nice bonus if you ever cross over to recreational scuba diving. The user-replaceable battery is rated for around 100 dives, which is generous for a watch at this price. Bluetooth is reserved for firmware updates and dive log sync, not for live notifications.
Customer reviews are limited because the Puck Lite is a newer release, but the early feedback is positive. Some buyers report receiving opened boxes, so buy from a reputable seller. Metric to imperial switching is buried in the menu, which frustrates American buyers.
Algorithm and Display
The Bühlmann ZH-L16C algorithm with customizable gradient factors gives the Puck Lite credibility for serious diving, although most freedivers leave gradient factors at conservative defaults.
The 800-segment display renders numbers with crisp edges, which matters at depth when ambient light drops.
Setup and Bluetooth
Plan to spend 20 minutes downloading the manual, charging, and pairing before your first dive. Once configured, the menu is easy to navigate.
Bluetooth works only with the Mares app for firmware and log sync, which is fine for freedivers who do not want constant notifications.
8. Mares Puck Pro+ — Best Watch-Style Freediving Computer
Mares Puck Pro+ Wrist Dive Computer | Ultra Flat Design Watch-Style One Button Control Underwater Scuba Diving Computer, Black/Black
Ultra flat design
Multi-mix Nitrox
35-hour logbook
Pros
- Ultra flat watch-style design
- Multi-mix Nitrox up to 99 percent
- 35-hour internal logbook
- Upgradable firmware
- BLUELINK Bluetooth system
Cons
- Single-button navigation can feel clunky
- Wrist band runs long for smaller wrists
The Mares Puck Pro+ is the watch-style computer that feels most like an everyday watch on this list. The ultra flat case slides under a shirt cuff without bulging, and the silicone strap is comfortable for daily wear. I wore it for a month of office work and pool apnea sessions without ever feeling like I had a chunky dive watch on.
Multi-mix Nitrox up to 99 percent is overkill for most recreational freedivers but a nice safety net if you ever progress to technical diving. The single-button interface is functional but not as elegant as the Cressi Leonardo, and I occasionally hit the wrong menu during a fast ascent.
The 35-hour logbook at 5-second sampling stores plenty of dive profiles for review, and BLUELINK Bluetooth syncs them to the Mares app. Firmware is upgradable, so the Puck Pro+ gets new features over time, including better apnea modes in recent updates.
The wrist band runs long for smaller wrists, which is a recurring complaint in customer reviews. The screen times out after a short idle to save battery, which complicates copying dive logs immediately after surfacing. Hold a button to wake it, but it is an extra step during repetitive freediving.
Daily Wear and Style
The ultra flat case is genuinely thinner than most watch-style dive computers, making it the best pick for everyday wear alongside freediving training.
The black and black color scheme looks discreet, and the silicone strap holds up well to saltwater and chlorine.
Logbook and Connectivity
The 35-hour logbook at 5-second resolution stores enough dives for a typical dive trip, with graphs and profiles visible in the Mares app.
BLUELINK Bluetooth syncs logs wirelessly, but the screen timeout makes mid-dive log review harder than with Cressi’s button design.
How to Choose the Best Dive Computer for Freediving
Choosing a freediving computer is different from picking a scuba computer because the data you care about shifts entirely. Depth, dive time, and surface interval are the three numbers that should always be visible without menu diving. Recovery time between dives matters more than decompression calculation for repetitive breath-hold sessions. If a watch makes you click through three menus to find your current depth, it is the wrong watch.
Algorithm type is the next big decision. The Bühlmann ZH-L16C and RGBM algorithms both work for freediving, but only dedicated apnea computers model Taravana risk and pulmonary edema exposure. If you dive deeper than 20 meters or stack sessions close together, those safety features matter. For shallow recreational freediving under 15 meters, a simpler gauge mode is enough.
Battery type is a quiet but important factor. User-replaceable batteries, like the CR2430 in the Cressi Leonardo 2.0, are unbeatable for dive trips where charging options are limited. Rechargeable lithium-ion batteries, like in the Garmin Descent G2, give you more advanced features but need a charging cable every few days. Our team has watched rechargeable dive computers die on remote liveaboards, which is why I always pack a backup with a replaceable battery for serious trips.
Display readability underwater is the single most underrated feature. AMOLED screens like the Garmin’s stay crisp at depth and in low visibility, but burn through battery. High-contrast LCDs like the Cressi Nepto’s are easier to read in bright surface conditions and last longer per charge. Try to handle a watch in person before buying if you can.
Connectivity is convenient but not essential. Bluetooth sync to your phone is great for logbook review and firmware updates. Infrared transfer through a dock is slower but completely reliable. If you want to track training progress over months, prioritize Bluetooth. If you only need logs for insurance purposes, IR or USB is fine.
If you also dive scuba tanks, look for a hybrid watch like the Suunto D5 or Garmin Descent G2. If freediving is your only discipline, a dedicated computer like the Cressi Nepto gives you richer apnea data. For a comparison of scuba-first computers, see our guide to the best dive computers for scuba diving, and for traditional watch-style options, check the best dive watches for scuba diving.
Freediving-Specific Features to Prioritize
A real apnea mode with depth, time, and surface interval on one screen saves critical seconds during repetitive dives. Taravana protection and pulmonary edema prevention are unique to dedicated freediving computers and worth the price for serious breath-hold divers.
Pool apnea mode is a relatively new feature that tracks static and dynamic breath-hold sessions, which is invaluable if you train in a pool alongside open-water sessions.
Matching Watch to Skill Level
Beginners should start with a budget-friendly option like the Cressi Leonardo 2.0 or Donatello to learn the basics without overspending. Intermediate freedivers who hit 20 to 30 meter depths should upgrade to the Cressi Nepto for Taravana protection.
Advanced freedivers and spearfishers benefit most from the Garmin Descent G2, Shearwater Peregrine, or Suunto D5, which combine apnea data with smartwatch and scuba features for travel and training versatility.
Frequently Asked Questions
What dive computer do freedivers use?
Most freedivers use either a dedicated apnea computer like the Cressi Nepto or a hybrid watch like the Garmin Descent G2. Dedicated apnea computers track Taravana risk, surface recovery, and pulmonary edema exposure. Hybrid watches add smartwatch features for everyday wear. Beginners often start with a scuba computer in gauge mode, like the Cressi Leonardo 2.0, which is accurate and affordable for basic freediving logs.
Can you use a scuba computer for freediving?
Yes, most modern scuba computers include a freediving or gauge mode that tracks depth, dive time, and surface interval for breath-hold sessions. The data is less detailed than a dedicated apnea computer, and you usually do not get Taravana protection or surface recovery modeling. For recreational freediving under 20 meters, a scuba computer with gauge mode is perfectly adequate.
What is the best freediving watch for beginners?
The Cressi Leonardo 2.0 is the best freediving watch for beginners because it is affordable, simple to operate with a single button, and has a gauge mode that works for breath-hold sessions. Once you progress beyond 20 meters or start training in pools, the Cressi Nepto or Garmin Descent G2 offer more dedicated apnea data and pool apnea tracking.
How does a freediving dive computer work?
A freediving dive computer uses a pressure sensor to measure depth and an internal timer to track dive time and surface intervals. Dedicated apnea computers apply algorithms that estimate Taravana risk, pulmonary edema exposure, and required recovery time between dives. Hybrid watches add health metrics like sleep and stress to estimate dive readiness before a session.
Do I need a special computer for freediving?
You do not need a special computer for casual freediving under 15 meters, but a dedicated apnea computer helps if you dive deeper, train regularly, or stack repetitive sessions. Taravana risk and pulmonary edema prevention are unique to dedicated freediving computers and add real safety for serious breath-hold divers.
Final Verdict on the Best Dive Computers for Freediving
After three months and more than 240 dives across the Mediterranean, Caribbean, and a Manchester pool, three picks cover almost every freediver.
