Best Budget Dive Computers 2026: Cressi Leonardo vs. Mares Puck Pro vs. Suunto Zoop Novo
Three budget dive computers dominate the entry-level market in 2026: the Cressi Leonardo, the Mares Puck Pro, and the Suunto Zoop Novo. Here is how they actually compare, and which one makes sense for a new diver.
What Is a Dive Computer (and Do You Need One)?
A dive computer tracks your depth and bottom time in real time and calculates your no-decompression limit as you dive, adjusting continuously based on your actual profile rather than a fixed table. That is the key difference in the “dive watch vs dive computer” question: a dive watch is just a rugged, water-resistant timepiece, while a dive computer is doing live decompression math and warning you before you get into trouble.
You do not strictly need to own one. Most dive shops rent computers for around ten to twenty dollars a day, and that is a fine way to start. But if you dive more than a handful of times a year, owning your own means you always know its history, its battery status, and its quirks, and you are not stuck with whatever rental unit is left at the counter. The three computers below are the models that consistently show up as the budget-tier standard, all landing well under the price of the dive-watch-style computers aimed at technical divers.
Head-to-Head: The Specs That Matter
| Spec | Cressi Leonardo | Mares Puck Pro | Suunto Zoop Novo |
|---|---|---|---|
| Depth rating | 120m | 150m | 80m |
| Battery | User-replaceable CR2430 | User-replaceable, roughly 400 hours / 200 to 300 dives | User-replaceable CR2450, roughly 1.5 to 2 years |
| Logbook memory | 60 dives / about 70 hours | About 36 hours | About 60 hours |
| Modes | Air, Nitrox, Gauge | Air, Nitrox, freshwater and gas-mix calibration | Air, Nitrox (to 50%), Gauge, Freediving |
| Data transfer | Optional separate interface | USB cable included | Optional USB cable + Suunto DM5 software |
| Interface | Single button | Three buttons | Three buttons, large 1.33 inch display |
| Price tier | Budget (typically the cheapest of the three) | Budget to mid | Budget to mid |
Exact pricing shifts with retailer and bundle, so treat the table above as a feature comparison rather than a quote. All three consistently land in the same general budget bracket, well below air-integrated or hoseless computers.
Cressi Leonardo: The Simplest Way In
The Leonardo has one job and does it with almost no learning curve: a single button cycles through its few screens, which is exactly why dive shops hand it to first-time buyers. It is rated to 120 meters (far deeper than any recreational diver should go), logs about 60 dives or 70 hours of dive time, and runs on a widely available CR2430 battery you can swap yourself. It offers Air, Nitrox, and Gauge modes, covering everything a new Open Water or Advanced diver needs. It is routinely cited as the cheapest true dive computer on the market, which is exactly why it shows up as the default “first computer” recommendation in so many buying guides.
Where it gives something up: there is no included USB cable, so pulling dive logs to a computer requires a separate interface accessory sold on its own.

Mares Puck Pro: Deepest Rating, Built-In USB
The Puck Pro is the deepest-rated of the three at 150 meters, though again, that number matters far less to a recreational diver than the everyday features. It ships with a USB cable in the box, so downloading dive profiles is plug-and-play with no accessory purchase. Battery life is excellent, commonly quoted around 400 hours or roughly 200 to 300 dives before a change, though the logbook itself holds a shorter roughly 36-hour window than the other two. It also supports freshwater and gas-mixing calibration, a small but genuinely useful feature set for divers who move between lake and ocean diving or start working with Nitrox regularly.

Suunto Zoop Novo: The Dive Shop Favorite
The Zoop Novo is the direct successor to the original Suunto Zoop, released in 2010 and long considered one of the best-selling entry-level dive computers in the world, and the Novo carries that reputation into 2026 as the computer you will see most often strapped to rental-fleet wrists at dive shops. Its standout feature is the display: a large, easy-to-read 1.33 inch screen behind tough acrylic that is hard to beat for readability in low visibility. It runs on a user-replaceable CR2450 battery that typically lasts a year and a half to two years of regular diving, logs about 60 hours of dive data, and is rated to 80 meters, shallower than the other two but still well past any recreational dive limit.
The Zoop Novo is also the only one of the three with a dedicated freediving mode alongside Air, Nitrox (to 50 percent), and Gauge modes, which makes it a reasonable pick for divers who split time between scuba and freediving. Like the Leonardo, USB data transfer requires an optional cable and Suunto’s DM5 desktop software rather than a built-in port.

Which One Should You Buy?
If price and simplicity matter most, the Cressi Leonardo is the easiest recommendation: cheapest, simplest single-button interface, and more than adequate specs for recreational diving. If you want the deepest rating, built-in USB, and don’t mind a shorter logbook window, the Mares Puck Pro is the pick, especially for divers who anticipate diving in both fresh and salt water. If display readability and long-term battery life matter most, or you also freedive, the Suunto Zoop Novo earns its reputation as the dive shop default for a reason.
None of the three is a wrong choice. Each has been a staple recommendation for new divers for years, which is exactly why they still dominate this price tier in 2026.
Where to Buy
Cressi Leonardo on Amazon · Mares Puck Pro on Amazon · Suunto Zoop Novo on Amazon
A dive watch is a rugged, water-resistant timepiece with no decompression calculations built in. A dive computer actively tracks your depth and bottom time and calculates your no-decompression limit in real time, then warns you as you approach it. For any dive that involves planning around nitrogen loading, a computer is doing real work a watch simply can’t.
Renting is a perfectly fine way to start, and most dive shops offer one for roughly ten to twenty dollars a day. Owning makes more sense once you’re diving regularly, since you always know the unit’s history and battery status instead of getting whatever is left at the counter.
The Cressi Leonardo. Its single-button interface cycles through the few screens you actually need, which is exactly why dive shops hand it to first-time buyers with almost no explanation required.
Not immediately, but it’s cheap insurance. All three computers here support Nitrox, and a large share of new divers earn a Nitrox certification within their first year or two, so having the mode already built in means you won’t need to replace your computer when you do.
The Suunto Zoop Novo has a dedicated freediving mode alongside its scuba modes, making it the most versatile pick if you split time between scuba and freediving. The Cressi Leonardo and Mares Puck Pro are built specifically for scuba, with Air, Nitrox, and Gauge modes only.
