Top 5 Beginner Dive Computers in 2025
Best budget: Suunto Zoop Novo
The Suunto Zoop Novo remains one of the most trusted entry-level dive computers among dive schools worldwide. Its massive display, conservative algorithm, and bulletproof reliability make it one of the safest choices for nervous beginners who want proven, instructor-approved technology. There are five dive modes including air, nitrox (21-50%), gauge, freediving, and off mode.
The Zoop Novo’s 2.6-inch face is one of the largest of any entry-level computer, making critical information impossible to miss even in low visibility. The four-button interface provides easier navigation than single-button competitors, while the conservative Suunto RGBM algorithm prioritizes safety over extended bottom time. It runs on a watch-style CR2450 battery that can last 1-2 years, but does need to be sent to an authorized dealer once it dies.
Where to Buy
What We Like
- Large and clear display
- Ultra-conservative algorithm prioritizes safety
- Four-button interface easier than single-button alternatives
- Bulletproof reliability—favorite of dive schools
- Water-activated operation
What We Don’t Like
- Very bulky design—cannot be worn as daily watch
- Conservative algorithm may limit bottom time as you get more experienced
- 48-hour lockout penalty for violations
Honorable mention: Cressi Leonardo 2.0
The Cressi Leonardo 2.0 offers similar entry-level functionality, also focusing on simplicity with a large monochrome display that’s easy to read underwater. While the Suunto Zoop’s display glows in the dark, divers will need a torch to illuminate the display. The Leonardo 2.0, on the other hand, has a built-in backlight for easy reading on night dives. A minor setback is the Leonardo’s one-button design, which isn’t complicated per se but will require some reading of the manual. Most users agree that the Zoop’s four-button is easier to navigate.
Running on a conservative RGBM algorithm, the Leonardo also features audible alarms that warn ascent speed, decompression, or PPO2 level violations. The Leonardo 2.0 also operates on a CR2450 battery, however this can be changed by the diver, eliminating the need to send it in for service, unlike the Zoop.
Best all-around: Cressi Raffaello
At $90 more than the Cressi Leonardo 2.0, the Cressi Raffaello represents a bit of a step up from the computers in our budget category. We have used this computer on countless dive trips, and every time we enjoy its large-yet-minimal design. The Raffaello has a large rectangular screen for better dive data display, a freediving mode, two-button navigation and a compass—a feature not often found in entry-level computers.
Our favorite feature of the Raffaello is its wide wrist display (2 x 1.4 inches/5 x 3.5 cm) that is still reasonably lightweight and slim, being only 0.6 inches (1.6 cm) high. The screen itself is a basic monochrome, which can be easily backlit. Rectangular screens tend to be easier to read as dive data is neatly displayed and organized. For beginners still getting to grips with all the new information, being able to grasp the essentials at a glance is a real plus.
The Cressi Raffaello is a strong choice for new divers who are willing to spend a little more and perhaps don’t want a large puck-sized dive computer that screams beginner.
Where to Buy:
What We Like
- Large, easy-to-read rectangular display
- Digital compass included
- Four-year battery life with user replacement
What We Don’t Like
- No air integration capability
- Monochrome display lacks color coding
Honorable mention: Scubapro Luna 2.0
If you like the look of a flat dive computer but are looking for something with a bit more functionality, then for just $50 extra the Scubapro Luna 2.0 offers a wide 2.8-inch (72 mm) display and air integration. The display is a high-contrast black and white screen with large characters and a bright LED backlight.
The biggest plus for the Luna 2.0 is that it offers wireless air integration, so you can monitor tank pressure and get remaining bottom time calculations. Divers will need to purchase a separate transmitter, so bear that in mind when considering the price.
The Luna 2.0 has extra details, for example divers can choose to remove the standard silicone strap and add their own bungee cords if they prefer. Bluetooth is built-in so you can download your dives to any phone or computer; the Raffaello requires purchase of a separate external Bluetooth connectivity device.
Best investment: Shearwater Peregrine
Shearwater is a well-known name in dive computers and, until recent years, produced computers geared primarily to technical divers. The release of the Shearwater Peregrine means novice recreational divers can now enjoy the professional-grade reliability that Shearwater delivers.
The Peregrine features Shearwater’s intuitive and easy-to-navigate menu. It has a 2.2” (5.5 cm) full-color LCD display, which is highly customizable so you can choose how and where to see the information important to you. The Peregrine also uses its colors to display changes such as NDL levels or tissue saturation, so if you find colors help you to segregate and organize information, the Peregrine is one to look at.
Although beginners won’t need it—yet—the computer is depth-rated to 395 feet (120 m), which means it can grow with you as a technical computer if you choose to advance your diving in that direction. The Peregrine supports air, nitrox, and as well more advanced 3-gas nitrox (a dive computer’s ability to switch between three nitrox mixes) and decompression diving. If you’ve caught the scuba diving bug, and want to invest in a high-end, beginner-friendly dive computer, the Shearwater Peregrine is a good choice.
Where to Buy:
What We Like
- Shearwater reliability at recreational price
- Fully customizable display (colors, fonts, layout)
- Supports progression into light technical diving
What We Don’t Like
- Larger size may overwhelm smaller wrists
- Higher price than basic computers
Honorable mention: Shearwater Peregrine TX
For divers who want the same trusted Shearwater technology with added convenience, the Peregrine TX offers wireless air integration and a built-in digital compass alongside all the Peregrine’s other features. The TX wirelessly connects to four tank transmitters, displaying real-time pressure and calculated air time remaining directly on the bright color screen, keeping all the data in one place.
If you are willing to invest (even more) in your first dive computer, we would always recommend going with one that has the option for a transmitter. Even if you don’t buy it right away, there is always the option if, or when, you want to advance.
Best for Apple users: Apple Watch Ultra/Oceanic+ App
If you already have an Apple Watch Ultra sitting on your wrist, then good news—you don’t need a new dive computer, you just need a subscription. The Oceanic+ app transforms your Apple Watch Ultra from an everyday smartwatch into a capable dive computer. While the Ultra itself is rated to 328 feet (100 m) depth, the diving abilities of the Oceanic+ app max out at 130 feet (40 m).
Through the app, divers can choose between air, nitrox (up to 40%) and freedive mode. There is a 3D tilt-compensated compass found off the main screen. Once installed on the Apple Watch Ultra, Oceanic+ app launches automatically when submerged and constantly calculates and monitors dive parameters. The 49 mm retina display is one of the best we have seen out of all the computers, providing exceptional clarity underwater.
The Oceanic+ app design is undeniably Apple, and users will find the watch app very intuitive and familiar. As part of the same ecosystem, Apple users can share their dives through the phone app, as well as use their location for local information on tides, water temperature, and access community-input data like visibility and currents, all helping you to safely plan your dive.
One major setback of the Ultra One was the battery, which lasted only 12 hours in dive mode. We have not tested the Oceanic+ app with more recent models, which promise longer battery lifes. This limited battery life, plus the subscription model ($9.99/month or $79.99/year) and 130-foot depth limitation make this watch best suited for casual vacation divers who are already immersed in the Apple ecosystem.
Where to Buy:
What We Like
- Premium smartwatch features (calling, apps, Apple Pay)
- Exceptional display quality with 49 mm screen
- Oceanic+ app provides exceptional dive logging and social features
What We Don’t Like
- Subscription required for full dive functionality ($5/day, $10/month or $80/year)
- 130-foot (40 m) depth limit restricts advanced diving
- No air integration available
Best sports watch: Garmin Descent G2
There was a little debate here in the office as to whether a sports watch can truly be classified as a “beginner” dive computer. Honestly? Not in the traditional sense. These are expensive pieces of equipment with a lot going on, with far more functionality than most novice divers need. However, nowadays, most of us are already wearing smart/sports watches, so having a dive computer already contained within our wrist devices offers real benefits.
If you’re already part of the Garmin ecosystem, the Descent Series is a natural choice since you’ll instantly feel at ease with the interface. If not, all the current Descents have 5-button navigation, and a touchscreen, so getting accustomed to a Garmin does take a bit of practice.
While it may not fit the classic definition of a “beginner” dive computer, we think the Garmin Descent G2 is a beginner-friendly sportswatch dive computer, at a reasonable value of $700.
An upgrade from its predecessor the G1, the G2’s 1.2-inch AMOLED color touchscreen with sapphire crystal provides exceptional underwater clarity. Dive-wise, the G2 covers everything from recreational nitrox to advanced technical configurations. During our battery test, the G2, like all the other Garmin Descent dive computers, lasted well beyond what was promised—Garmin states 27 hours, and ours clocked out after 39 hours.
As a fitness smartwatch, it offers 100+ sports activities, advanced health monitoring, and seamless integration with Garmin’s ecosystem. All Garmin Descent dive computers can access Garmin’s general Connect App and its specific Dive App.
Where to Buy
What We Like
- Vibrant AMOLED touchscreen display
- 100+ sports activities with advanced fitness tracking
- Eco-friendly construction using recycled materials
- 27-hour dive battery life (39-hour when tested)
- Full Garmin Connect ecosystem integration
What We Don’t Like
- Steep learning curve compared to simpler computers
- Premium price point
Honorable mention: Suunto Ocean
The Suunto Ocean is also a smart sportswatch-dive computer, and offers an excellent alternative to Garmins. The display is a 1.43” (36 mm) AMOLED full-color touchscreen, with the highest-resolution display to date. The Ocean has 3-button navigation, and the buttons have a soft yet secure feel, unlike the G2’s, which are stiffer to push.
While both have an integrated compass, the Ocean does stand out via its capability of air integration with up to five transmitters. The Suunto does lack the advanced technical modes of the G2 and increased depth rating— only 196 feet (60 m) versus 330 feet (100 m).
The Ocean’s health monitoring includes tracking for sleep, heart rate, steps, and stress. Both the G2 and the Ocean cover a wide range of 100 sports. The main difference here is that the Ocean lacks the depth of Garmin’s training ecosystem, such as advanced cycling dynamics, stairs climbed, swim stroke rate etc. which, in turn, means less-detailed long-term insights.
Why Trust Us
Our recommendations come from extensive real-world testing across diverse diving environments. We’ve guided hundreds of new divers through their first computer purchase, and we understand exactly what features matter most during those crucial early dives.
We test every computer in scenarios from in-office evaluations to shallow training sessions and advanced recreational dives—assessing readability, ease of use, and reliability when it matters most.
All dive computers perform our standard battery test. We place them into a mini-pressure chamber, charge them to 100%, set them to full brightness, turn off any kind of transmitter capabilities, and keep the computer at 20 feet (6 m) continuously.
We also evaluate long-term value, and many of our recommended models can accompany you from Open Water through to Divemaster training.
Usability & menu navigation
How easy it is to use your brand-new computer is probably the single most important factor when deciding on a purchase. That doesn’t mean the computer itself has to be the simplest one on the market—just that you feel comfortable with it in the water.
→ Simplicity trumps features for new divers. Look for computers with intuitive, two-button interfaces rather than complex multi-button systems. The best beginner computers let you access critical information—depth, dive time, NDL—without scrolling through multiple screens.
→ Consider your comfort with technology. If you’re already comfortable with smartphones and apps, using computers like the Apple Ultra/Oceanic+, Garmin Descent series, or Suunto Ocean will come more naturally. If you prefer simple, dive-dedicated devices, Cressi computers offer straightforward operation without complexity.
Display Quality
How your dive data is displayed is the next important factor to consider, and it comes down to two main elements. First is shape— do you want a round or rectangular computer? Rectangular displays usually offer a cleaner layout with better separation of information. Second is color on the screen— or lack of it—and this personal preference. Just make sure to factor in your own vision.
→ Size matters for new divers. Larger displays make it easier and faster to check vital information, letting you maintain awareness of your surroundings. Rectangular computers like the Cressi Raffaello maximize screen real estate, while round, watch-like computers, like the Garmin G2, can feel more natural to wear.
→ Screen readability underwater is crucial. Large, high-contrast displays with big numbers reduce anxiety during dives. Many beginners struggle to read small displays while managing other diving skills, making readability a safety issue.
→ Color vs. monochrome depends on personal preference. Color displays (Suunto Ocean, Apple Ultra, Scubapro Luna) offer intuitive color-coding for different data types. Monochrome displays, such as on the Cressi computers and Suunto Zoop Novo, often provide better contrast and longer battery life.
Depth Rating
For the most part, depth rating isn’t too crucial when choosing your first dive computer as all will cover the recreational limit of 130 feet (40 m) as a bare minimum. As a starting point, we do recommend 196 feet (60 m) for peace of mind. This way your computer will still support you and keep you safe if you exceed your limits.
→ Recreational diving rarely exceeds 100 feet (30 m), but almost all dive computers will have a limit of at least 196 feet (60 m). The Apple Ultra’s 130-foot limit (40 m) restricts some advanced training dives, but having a computer with a deeper rating can provide safety margins and peace of mind.
→ Consider your diving ambitions. If you plan to pursue Divemaster or technical certifications, choose computers that won’t limit your progression, such as Shearwater Peregrine or Cressi Raffaello.
Conservatism and algorithms
As a new diver, you’re likely to feel more stress and anxiety than someone with more experience. That’s why it’s a good idea to choose a dive computer with a more conservative algorithm—because when you’re just starting out, the last place you want to be is anywhere near your no-decompression limits.
→ Conservative algorithms prioritize safety over extended bottom time. New divers tend to be anxious, and erring on the side of caution is never a bad thing when starting out.
→ Adjustable conservatism (available on the Shearwater Peregrine and Suunto Ocean) lets you start conservatively and adjust settings as experience grows. This flexibility means you won’t have to upgrade your computer as your skills advance.
Price considerations
Just as with everything else in life, you get what you pay for when it comes to dive computers—but that doesn’t mean you need to spend loads of cash to get what you want, especially if you want to start simple.
→ Set a realistic budget including accessories. Basic computers start around $300, while feature-rich models can reach $800-900. Consider total costs including protective cases, screen protectors, and potential subscription fees.
→ Balance current needs with future growth. Spending slightly more upfront on computers like the Shearwater Peregrine or Suunto Ocean may eliminate the need for upgrades as diving skills advance, providing better long-term value. However, if you’re not sure you’ll dive very much, you can spend conservatively on a simpler computer, like the Suunto Zoop, which can serve you well for years as a recreational diver.
Extra features worth considering
Air integration
Definitely not a need-to-have, a transmitter is always a nice-to-have, especially for your future as a diver. Having air integration allows you to see data such as remaining air, remaining air time and SAC rate (Surface Air Consumption—a diver’s gas usage per minute) displayed neatly on your wrist.
→ Wireless air integration displays tank pressure directly on your computer, eliminating the need for separate gauges. The Suunto Ocean supports up to five transmitters, while the Shearwater Peregrine TX handles four.
→ For beginners, air integration reduces equipment complexity by consolidating information in one place. However, it adds cost ($300-400 per transmitter) and introduces potential failure points. We never recommend that a transmitter should replace your SPG.
Dive modes and evolution potential
All dive computers nowadays include air and nitrox, which is all new recreational divers will ever need. Since dive computers already include a depth gauge and timer, usually an apnea/freediving mode is thrown in as well. You only need to think about more advanced dive modes, like trimix or multi-gas support, if you already know you’re aiming to progress into technical diving.
→ Multi-gas capability allows progression into advanced nitrox and light technical diving without computer upgrades. The Shearwater Peregrines, Garmin G2, and Scubapro Luna 2.0’s technical modes provide excellent growth potential.
Smartwatch functionality
A new wave of dive computers, these sportswatch models are not your traditional beginner dive computer. If you are considering a new sportswatch and a new dive computer, then getting a 2-in-1 device could save you money and simplify your gear setup.
→ Smartwatch/sports watch dive computers are the newest kids on the block. Computers like the Suunto Ocean, Apple Watch Ultra and all the Garmins, are valuable daily companions for those with active lifestyles. Their smart notifications, music control, and app ecosystems enhance user experience for tech-savvy divers who like to have one device.
→ Consider lifestyle integration. If you already use fitness trackers or smartwatches, upgrading to a dive-capable model provides better value than separate devices. Although they are considerably more expensive than the more basic models in this guide, they are essentially two watches in one, justifying higher costs.
Final recommendations
There are many more dive computers for you to choose from, whether they be big or small, basic or smart. The most important thing to do before you buy your first dive computer is to assess and understand what features are crucial to you and which are just nice to have.
How much will you use the computer? How comfortable are you with technology? And how much of your budget can you afford to dedicate to a single piece of equipment if you’re considering buying a full kit?
Ask your dive buddies and instructors what they use; rent a few computers from your local dive shop; dive deep into forums or watch reviews to get a clearer picture of what matters to you and what you are willing to pay for.
The best beginner dive computer is the one you’ll actually use confidently.
Take a moment to look at this.
