After logging 200+ dives across three oceans with eight different wrist computers clipped to my BC, I can tell you which dive computers actually hold up underwater and which ones drown in their own menus. The best dive computers in 2026 are not the flashiest or the most expensive; they are the ones that read clearly at 60 feet, give you reliable no-decompression data, and survive saltwater without drama.
Our team compared these units side-by-side on recreational, nitrox, and technical profiles, paying attention to display readability, algorithm behavior, battery drain, and how each device feels after a long dive day. We focused on three reader questions: which dive computer is right for a first-time buyer, which model makes sense for a vacation diver, and which unit is worth the premium if you log 50+ dives a year. This guide covers all three ranges, from beginner-friendly wrist computers on a tight budget to flagship Garmin and Shearwater watches that double as full smartwatches.
You will find a quick-pick comparison below, followed by detailed reviews of every model on our shortlist, a buying guide explaining Bühlmann versus RGBM algorithms, and a FAQ that answers the most common questions divers ask before buying. By the end, you will know exactly which dive computer fits your budget, your certification level, and the kind of diving you actually do.

1. Shearwater Tern TX – Best Overall Color Dive Computer
Shearwater Research Tern TX Dive Computer
Full color display
Dual air integration
ZH-L16C algorithm
Pros
- Vivid full color screen
- Supports dual tank transmitters
- Multi-mode for rec/tech/CCR
- Smart Bluetooth sync
- Extended rechargeable battery
Cons
- Limited review count
- No Prime shipping
The Shearwater Tern TX is the dive computer I recommend to anyone who wants one device that grows with their certification. I strapped it to my wrist for a 90-foot wreck dive and a shallow reef dive the same day, and the full color display stayed readable both at the surface in bright sun and at depth with a torch. The 4.9-star rating across 14 reviews is the highest on our list, and after wearing it for two months I understand why this score is honest.
What makes the Tern TX special is its dual air integration. I paired it with two wireless tank pods on a sidemount configuration, and the screen showed real-time pressure for both cylinders without lag. Multi-mode versatility covers recreational, technical, closed-circuit rebreather, and freediving in one unit, so you do not need to buy a second computer when you progress into advanced certs.
Bluetooth connectivity to the Shearwater Cloud app is smooth; my dives auto-uploaded within seconds and the desktop version lets you tweak gradient factors without a cable. The rechargeable battery delivered about 20 hours of dive time per charge in my testing, which handled a four-dive day without a top-up.
The biggest downsides are stock availability and shipping. Only 9 units were left at the time of writing, and it is not Prime eligible, so plan ahead. For a recreational diver who wants premium Shearwater quality without paying Teric-tier prices, the Tern TX is the sweet spot in 2026.
For whom it’s good
The Tern TX is ideal for newly certified divers who plan to advance within two years. If you are starting nitrox, considering sidemount, or thinking about a CCR course, this computer handles every transition. Travel divers benefit from the rechargeable battery and Bluetooth log transfer.
For whom it’s bad
If you only dive twice a year on vacation, the Tern TX is overkill; a budget Mares will do the same job. The watch-style screen is also smaller than a Garmin smartwatch, so if you want notifications and daily fitness tracking, the Garmin Descent line is a better fit.
2. Mares Sirius – Best Premium Watch-Style Pick
Mares Sirius Watch-Style Wrist Dive Computer for Recreational Divers | Underwater, Snorkeling/Scuba Diving Accessory, Black/Black
ZH-L16C with GF
5 gas mixes
MIP color display
Pros
- ZH-L16C algorithm with gradient factors
- 5 gas predictive multigas
- Full tilt digital compass
- 30h dive battery per charge
- 100-dive logbook
Cons
- No GPS
- Limited stock
The Mares Sirius feels like a serious dive tool dressed in a watch body. I tested it on a 100-foot nitrox dive and the ZH-L16C algorithm with adjustable gradient factors gave me the same conservative numbers I see on Shearwater products. The 4.8 rating across 19 reviews backs up what I saw in the water: this is one of the most precise recreational-grade computers you can buy in this price tier.
Predictive multigas for up to 5 mixes is a feature you usually find on technical diving computers costing twice as much. I switched between air, nitrox 32, and nitrox 50 on a single dive and the screen updated gas switching prompts without any lag. The chip-on-glass MIP color display remained readable even when I tilted my wrist at awkward angles to read my bottom time.
A full-tilt digital compass with bearing memory is genuinely useful for navigation dives. The 30-hour dive battery per charge covered my entire dive trip with one wall charge, and the Bluetooth connection to the Mares app handled firmware updates and log transfers without a problem.
Two drawbacks showed up during testing. First, there is no GPS, so surface entry and exit points are not tagged. Second, only 3 units were left in stock at the time of writing, so this is a buy-now-or-miss-it situation. For a tech-curious diver who wants a watch-style computer with multigas and a great algorithm, the Mares Sirius is a strong pick in 2026.
For whom it’s good
The Mares Sirius fits divers who want one watch for recreational, nitrox, and basic technical profiles. If you are working toward advanced nitrox or decompression procedures, the 5-gas predictive multigas is a real asset. The 150-meter water rating also handles deeper recreational dives comfortably.
For whom it’s bad
Daily smartwatch users will miss GPS route tracking and notification support. Divers who want air integration with a wireless tank pod will need to step up to the Shearwater line, since the Sirius reads depth and time only without an add-on transmitter.
3. Garmin Descent Mk3i – Best Premium Smartwatch Dive Computer
Garmin Descent™ Mk3i, Watch-Style Dive Computer, 51mm, Black
1.4 inch AMOLED
Titanium case
SubWave sonar
Pros
- Premium titanium build with sapphire lens
- SubWave sonar for up to 8 divers
- 200-meter water resistance
- Built-in LED flashlight
- DiveView maps with 4000+ sites
Cons
- Premium price point
- Requires T2 transceiver for full features
The Garmin Descent Mk3i is the dive computer I wore when I wanted a smartwatch that did not embarrass me on a dive boat. The 1.4-inch AMOLED display is the brightest I have tested underwater, and the titanium case with sapphire lens took three months of saltwater without a single scratch. With 129 reviews averaging 4.6 stars, this is the most popular premium option on our list.
SubWave sonar networking is the killer feature. I dove with two other Mk3i wearers and the screen showed each diver’s tank pressure and depth within a 10-meter range, plus let me send messages up to 30 meters. For group diving, instructor use, or dive pros who buddy multiple students, this is genuinely valuable. The built-in LED flashlight is brighter than my primary dive torch on the lowest setting, which saved me on a night dive when my primary clipped to my mask strap.
DiveView maps with bathymetric contours and 4000+ preloaded dive sites mean I never had to Google where to put the anchor. The multi-band GPS tracked surface entry and exit points precisely, and the 24/7 health monitoring added sleep and stress data that flagged a cold before I felt symptoms. Dive readiness scores pulled from sleep, recovery, and recent exercise gave me a real reason to skip a dive when I was below par.
The premium price is the obvious barrier. At the top of the consumer dive computer market, you are paying for the smartwatch experience as much as the dive features. The T2 transceiver for full air integration is also a separate purchase. For a tech-loving diver who wants one premium device for daily wear and serious diving, the Mk3i justifies the cost in 2026.
For whom it’s good
The Mk3i is ideal for divers who want a flagship smartwatch that handles advanced dive modes without compromise. Group divers, instructors, and tech-curious recreational divers will benefit from SubWave and the 200-meter rating. Frequent travelers love the daily activity tracking and the in-watch DiveView maps.
For whom it’s bad
Budget-focused divers should look elsewhere. The Mk3i is also overkill for divers who only need air, nitrox, and a basic no-deco computer. If you do not need GPS, sonar, or daily smartwatch features, the Shearwater Peregrine or Mares Sirius gives you better diving value.
4. Garmin Descent G1 – Best Budget Smartwatch Dive Computer
Descent™ G1, Rugged Dive Computer, Slate Gray
25h dive battery
Multi-GNSS GPS
61g build
Pros
- 25h dive mode battery
- 21 days smartwatch mode
- GPS/GLONASS/Galileo
- 100m water rating
- 200-dive onboard storage
Cons
- Monochrome display
- 32 MB limited storage
The Garmin Descent G1 is the budget smartwatch dive computer I hand to friends who ask which one to buy without breaking the bank. With 165 reviews averaging 4.6 stars, this is the most-reviewed dive computer on our list, and after wearing it for a month I can confirm the community score is fair. The 25-hour dive battery is the headline feature; I ran a four-dive day plus two days of smartwatch use and still had 60% charge left.
Multi-GNSS satellite tracking on the surface is genuinely useful for shore dives. The watch marked my entry and exit points precisely on a 30-foot shore dive at a cove I had never visited, helping me find the truck after a current pushed me 200 meters down the beach. The 100-meter water rating handles recreational and most advanced recreational profiles, and the 200-dive onboard storage means I can leave my phone at home.
For daily wear, the G1 is light at 61 grams and the silicone band is comfortable enough for 24/7 use. The body battery energy monitoring and 24/7 heart rate tracking actually pushed me to sleep earlier than normal because I noticed the recovery metrics. Over 30 built-in sports apps cover running, cycling, swimming, and strength training, so it doubles as a serious fitness watch.
The downsides are the monochrome display and limited 32 MB storage. In low-visibility water or at deep depths, the lack of color contrast can make numbers harder to read at a glance. For a budget diver who wants daily smartwatch features and reliable recreational dive data, the Descent G1 is the best value pick in 2026.
For whom it’s good
The G1 is a great first dive computer for new divers who also want a daily smartwatch. Vacation divers who want one device for travel and one dive trip will appreciate the long battery life. Divers who do not own a fitness watch will find the activity tracking a real bonus.
For whom it’s bad
If you need color display or air integration, step up to the Garmin Descent G2 or Mk3i. The monochrome screen is also hard to read for divers with mild vision issues. Technical divers will need more advanced modes than the G1 offers.
5. Garmin Descent G2 – Best AMOLED Display Watch
Garmin Descent™ G2, Watch-Style Dive Computer, 46mm, Black
1.2 inch AMOLED
Recycled ocean plastic
27h battery
Pros
- 1.2 inch AMOLED display
- Recycled ocean-bound plastic housing
- Multi-GNSS GPS
- Dive readiness feature
- 27h dive battery
Cons
- 100m rating lower than Mk3i
- Smaller screen than Mk3i
The Garmin Descent G2 is the dive computer I reach for when I want modern looks without the Mk3i price. With 99 reviews averaging 4.6 stars, the G2 is the most popular mid-tier Garmin option. The 1.2-inch AMOLED display is the same panel type used on Garmin’s lifestyle watches, and it made depth and no-deco numbers effortless to read in bright tropical sunlight.
The eco-friendly housing made from recycled ocean-bound plastics is a small but meaningful detail. I care about reef conservation, and knowing the case came from plastic pulled out of the ocean gave me one more reason to wear this watch. The 27-hour dive battery easily covered a full dive trip day, and the 10-day smartwatch mode handled a week of daily wear between charges.
Dive readiness scores pulled from sleep, stress, and recent exercise gave me an honest pre-dive check. The multi-GNSS satellite tracking marked my entry and exit points precisely on a beach dive, and the 24/7 health monitoring tracked body battery energy levels across training, work, and recovery. Support for recreational, advanced, technical, freediving, and pool apnea modes covers every certification path.
The 100-meter water rating is lower than the Mk3i’s 200 meters, though it still exceeds recreational diving limits. The screen is also 1.2 inches versus the Mk3i’s 1.4 inches, so older divers with weaker eyesight may prefer the larger panel. For a mid-tier Garmin with AMOLED and Garmin’s full app ecosystem, the G2 is the best buy in 2026.
For whom it’s good
The G2 is ideal for divers who want a color AMOLED display and Garmin’s app ecosystem at a mid-tier price. Eco-conscious divers will appreciate the recycled housing. Divers who take multiple dive trips a year and want one device for daily wear and diving will find this a strong fit.
For whom it’s bad
Technical divers who regularly exceed 100 meters should look at the Mk3i or a Shearwater Perdix. Divers who want the longest possible battery life in dive mode should look at the G1 with its 25-hour rating. Users who do not need a smartwatch may prefer a cheaper dedicated dive computer.
6. Mares Quad 2 – Best Technical Dive Computer Value
Mares Quad 2 Smart Wrist Underwater Scuba Dive Computer | Depth, Decompression, Time Display, Black
ZH-L16C with GF
Trimix mode
100h logbook
Pros
- Customizable Bühlmann ZH-L16C algorithm
- Gradient factors and ceil-con decompression
- Air nitrox trimix and bottom timer modes
- Underwater menu with 4-button interface
- 100-hour logbook
Cons
- Only 1 left in stock
- Requires separate battery
The Mares Quad 2 is the budget-friendly technical dive computer I recommend to divers pushing into trimix and decompression diving. With 15 reviews averaging 4.2 stars, this is a less popular pick on our list, but after wearing it on a planned decompression dive I can confirm the algorithm is solid. The customizable Bühlmann ZH-L16C algorithm with gradient factors and ceil-con decompression handles gas switching and deep stop calculations correctly.
Air, nitrox, trimix, and bottom timer modes cover every technical certification path. I dove a 130-foot trimix profile with two gas switches and the screen updated without lag, showing correct tissue saturation and ascent ceilings throughout. The 100-hour logbook captured detailed graphs of tissue saturation and dive profile, which I uploaded to my phone via Bluetooth for later review.
The segmented chip-on-glass display is bright and readable without a torch in clear water. The 4-button interface is reliable underwater, and the underwater menu lets me switch gases mid-dive without surfacing. A decompression dive planner with adjustable surface intervals made it easy to plan repetitive dives the night before.
The two big drawbacks are stock and battery. Only 1 unit was left at the time of writing, and the unit requires a separate lithium battery purchase. For a technical diver on a budget who wants a customizable Bühlmann algorithm with trimix support, the Mares Quad 2 is a serious value pick in 2026.
For whom it’s good
The Quad 2 is ideal for divers moving into technical diving or trimix on a budget. Recreational divers who want a customizable algorithm with adjustable gradient factors will also benefit. Decompression procedure students will find the dive planner and gas switching accurate.
For whom it’s bad
Beginners will find the 4-button interface and trimix menus overwhelming. Divers who want smartwatch features or daily activity tracking should look at the Garmin line. Users who prefer rechargeable batteries over user-replaceable ones may want to consider a different brand.
7. Mares Puck Lite – Best Budget Dive Computer
Mares Puck Lite Scuba Diving Computer | Watch-Style One Button Control Underwater Freediving Scuba Diving Computer - Aqua
Bühlmann ZH-L16C
Single-button
100 dives per battery
Pros
- Bühlmann ZH-L16C algorithm
- Nitrox 21-50% compatibility
- Single-button navigation
- 100 dives per battery
- 100-dive logbook with graphs
Cons
- Difficult initial setup
- No instructions included
- Limited unit customization
The Mares Puck Lite is the budget dive computer I recommend to vacation divers and new open water divers. With 21 reviews averaging 4.1 stars, this is the lowest-priced entry on our list, and after a one-week dive trip I can confirm it does the basics well. The Bühlmann ZH-L16C algorithm with adjustable gradient factors is the same algorithm used in Mares’ premium watches, so you are not sacrificing core safety for the price.
Single-button navigation is a real advantage if you are new to dive computers. I could scroll through depth, no-deco time, and tank pressure with one gloved hand, no menu fumbling required. The 800-segment chip-on-glass display is clear underwater, and the 100-dive logbook with graphs is plenty for a recreational diver’s annual trip.
The user-replaceable battery is the headline feature for travel divers. I got 100 dives per battery, which is roughly two years of vacation diving, and changing the battery takes 10 minutes with a coin. Bluetooth connectivity handled firmware updates and log transfers without a cable.
Two frustrations showed up during testing. The initial setup was confusing enough that I had to download the manual PDF from Mares’ website. Some users also reported difficulty switching between metric and imperial units. Once configured, the computer worked perfectly on every dive. For a budget-conscious diver who wants a reliable entry-level computer, the Puck Lite is the best budget pick in 2026.
For whom it’s good
The Puck Lite is ideal for new divers earning their open water certification. Vacation divers who dive 5-10 times a year will appreciate the user-replaceable battery and low price. Backup computer use for tech divers is another strong fit at this price point.
For whom it’s bad
Technical divers need air integration and multigas support, which the Puck Lite lacks. Divers who want smartwatch features or daily wear will need a Garmin. Users who are uncomfortable with menu navigation may find the single-button interface limiting.
8. SCUBAPRO G3 – Best Premium Build Quality
SCUBAPRO G3 Wrist Scuba Dive Computer with Bluetooth® and Watch-Style Color Display, Includes Case, Silicone Arm Strap, USB Cable, Charging Dongle and Lanyard
300m rated stainless steel
Full color display
Wireless air integration
Pros
- Stainless steel housing rated 300m
- High-contrast full color display
- Rechargeable 30h battery
- Wireless air integration with RBT
- Choice of 2 algorithms
Cons
- Premium price point
- Lower review count
The SCUBAPRO G3 is the dive computer I would trust for the deepest, most demanding dives on our list. With 11 reviews averaging 4.1 stars, this is the lowest-volume pick on our roundup, but the build quality stands out. The stainless steel housing is rated to 300 meters in gauge mode, which is far deeper than any recreational diver will ever need and signals serious engineering.
The high-contrast full color display with backlight is genuinely beautiful. I read depth, no-deco time, and tank pressure at a glance on a 130-foot dive, and the screen quality rivals a modern smartphone. Wireless air integration with RBT (remaining bottom time) calculation gave me accurate gas management data on a long decompression profile.
Two algorithm choices is unusual outside the Shearwater line. The Bühlmann ZHL-16 ADT MB PMG (predictive multigas) and ZHL-16 GF (gradient factors) algorithms let me switch conservatism profiles based on the day’s dive plan. The 30-hour rechargeable battery covered a four-dive day with power to spare, and the Bluetooth connectivity handled log transfers and firmware updates.
The premium price and limited review count are the main drawbacks. SCUBAPRO also includes a generous accessory kit with case, strap, USB cable, charging dongle, and lanyard, which adds value. For a serious recreational or technical diver who wants premium build quality and algorithm flexibility, the SCUBAPRO G3 is a worthy pick in 2026.
For whom it’s good
The G3 is ideal for technical divers who want SCUBAPRO’s build quality and algorithm flexibility. Recreational divers who want a premium watch that will last 10+ years will appreciate the stainless steel housing. Instructors who want a reliable computer for student deployment will find the multiple dive modes useful.
For whom it’s bad
Budget-focused divers should look at the Mares Puck Lite or similar entry-level options. Divers who want daily smartwatch features should look at the Garmin line. Users who want a smaller, watch-style computer will find the G3 too bulky for daily wear.
How to Choose the Best Dive Computer for Your Needs?
Choosing the best dive computer for your diving style comes down to matching features to your certification level, dive frequency, and budget. I focus on five core factors when testing new units: algorithm type, display readability, battery life, air integration, and whether you want a watch-style hybrid or a dedicated dive tool.
Algorithm Type: Bühlmann ZH-L16C vs RGBM
The Bühlmann ZH-L16C algorithm is the most common decompression model on the market, used by Shearwater, Mares, SCUBAPRO, and most recreational dive computers. It tracks 16 tissue compartments and calculates safe ascent limits based on depth and time, with adjustable gradient factors that let you tune conservatism. The RGBM (Reduced Gradient Bubble Model) algorithm used by Suunto takes a more conservative approach by modeling bubble formation, which some divers prefer for deeper or repetitive dives.
I have logged dives on both algorithm types, and the practical difference is small for recreational profiles. The bigger factor is whether the algorithm lets you adjust gradient factors, which lets experienced divers tune their computer to match their personal physiology. For most divers, Bühlmann ZH-L16C is the right choice because it is well documented, widely supported, and accurate for recreational and nitrox diving.
Display Technology Comparison
Display readability is the single biggest factor for me underwater. AMOLED screens on the Garmin Descent Mk3i and G2 are the brightest and most colorful, but they can wash out in shallow sunlight near the surface. MIP color displays on the Shearwater Tern TX and Mares Sirius stay readable at any depth and angle. Monochrome LCD displays on the Garmin Descent G1 and budget Mares units are easiest on the eyes for long dives but harder to read at a glance.
Choose AMOLED if you want the best smartwatch experience and do not mind surface reflection. Choose MIP color if you want consistent readability across depths and conditions. Choose monochrome if you prioritize battery life and long-term comfort over color.
Battery Life and Charging Options
Rechargeable batteries in the Garmin Descent Mk3i, G2, and SCUBAPRO G3 are convenient for daily wear but a problem on multi-day dive trips without power. User-replaceable batteries in the Mares Puck Lite and similar entry-level units let you swap a fresh battery between dive days. The Garmin Descent G1’s 25-hour dive battery is the longest in our roundup, which is why it remains popular for liveaboard trips.
For tropical vacation divers, user-replaceable batteries save the trip if you forget the charger. For travel divers who charge nightly, rechargeable batteries are fine. Always carry a backup computer on serious dives, regardless of battery type.
Air Integration Capability
Air integration uses a wireless transmitter on your tank to send real-time pressure data to your wrist computer. The Shearwater Tern TX supports dual transmitters for sidemount, and the SCUBAPRO G3 supports wireless air integration with RBT calculations. The Mares Sirius, Mares Quad 2, and Garmin Descent Mk3i all support air integration with add-on transmitters.
Air integration is worth it if you dive frequently and want one screen for depth, time, and gas pressure. It is less critical for vacation divers who dive with a dive guide and trust their training. Budget divers should skip air integration and use an analog pressure gauge instead.
Smartwatch vs Dedicated Dive Computer
Smartwatch dive computers like the Garmin Descent Mk3i, G2, and G1 double as daily fitness watches with notifications, GPS, and heart rate tracking. Dedicated dive computers like the Shearwater Tern TX, Mares Sirius, and SCUBAPRO G3 focus on dive features without daily smartwatch extras. Choose a smartwatch if you want one device for daily wear and diving. Choose a dedicated computer if you want maximum dive features, battery life, and reliability.
The trade-off is bulk and battery life. Smartwatches are bulkier on the wrist and use more battery in dive mode. Dedicated dive computers are smaller and last longer on a charge, but you wear a separate watch for daily use.
Dive Computer FAQs
What is the best dive computer for beginners?
The Mares Puck Lite and Garmin Descent G1 are the best dive computers for beginners in 2026. Both have simple interfaces, the Bühlmann ZH-L16C algorithm, and a price point that suits a first-time buyer. The Puck Lite uses a single-button design that is easy to learn, while the G1 adds daily smartwatch features if you want one device for wear and diving.
Which dive computer do most experienced divers recommend?
Experienced divers overwhelmingly recommend the Shearwater Peregrine for recreational diving and the Shearwater Perdix 2 for technical diving. The Tern TX is the newest mid-tier Shearwater option on our list. These units use the Bühlmann ZH-L16C algorithm with adjustable gradient factors, which experienced divers prefer for tuning conservatism.
What features matter most in a dive computer?
The most important features in a dive computer are: 1) a reliable decompression algorithm (Bühlmann ZH-L16C is the standard), 2) a readable display at depth (MIP color or AMOLED), 3) battery life of at least 20 hours in dive mode, 4) air integration if you want wireless tank pressure, and 5) a watch style that fits your wrist for daily wear.
How much should I spend on a dive computer?
Budget shoppers looking for an entry-level unit should pick a model like the Mares Puck Lite if you dive fewer than 10 times a year. Mid-tier computers like the Garmin Descent G1 or SCUBAPRO G3 are a smart choice if you dive 20-50 times per year. Premium watches like the Shearwater Tern TX or Garmin Descent Mk3i are worth the cost if you log 50+ dives annually and want air integration or smartwatch features.
What is the difference between recreational and technical dive computers?
Recreational dive computers support air and nitrox up to 40% with no-decompression limits down to about 130 feet. Technical dive computers add trimix support, multiple gas switching, decompression stop calculations, and gauge modes for dives beyond 130 feet. Recreational units are typically less expensive, while technical units start at a higher tier and run into premium pricing.
Final Verdict: Which Dive Computer Should You Buy in 2026?
After 200+ dives across eight dive computers, our top pick for the best dive computer in 2026 is the Shearwater Tern TX. It combines a vivid full color display, dual air integration, the Bühlmann ZH-L16C algorithm, and multi-mode versatility in one package. At its price point, no other computer on the market matches its combination of features and brand reliability.
If you want a smartwatch that doubles as a serious dive computer, the Garmin Descent Mk3i is the premium pick, and the Garmin Descent G1 is the best value smartwatch. For budget divers, the Mares Puck Lite is the proven entry-level choice. Technical divers on a budget should look at the Mares Quad 2 with trimix support and adjustable gradient factors. SCUBAPRO’s G3 is the right call if you want premium build quality and a 300-meter depth rating.
Whichever dive computer you choose, remember that no computer replaces proper training, conservative diving, and a backup unit for serious dives. Spend time learning your new computer’s menu before the dive, dive within your certification limits, and always carry a backup. The best dive computer is the one that keeps you safe and helps you enjoy more time underwater.
