Best for
- The best all-round computer that grows with you: Shearwater Peregrine, flexible Buhlmann algorithm and a superb interface
- The cheapest, most rugged beginner computer: Suunto Zoop Novo, with a user-replaceable battery
| Shearwater | Suunto | |
|---|---|---|
| Key models | Peregrine, Peregrine TX (air integration) | Zoop Novo (budget), Ocean and D5 (premium) |
| Interface | Large colour screen, intuitive 2-button | Zoop Novo 4-button mono screen; Ocean colour touchscreen |
| Algorithm | Buhlmann GF, adjustable to extend bottom time | RGBM, which many find conservative |
| Battery | Rechargeable | Zoop Novo user-replaceable; Ocean and D5 rechargeable |
| Rough price (2026) | Peregrine at USD 580; TX at USD 760 | Zoop Novo at USD 299.95, listed as a promotional price; Ocean sits well above it, though we could not confirm a current price at source |
| Air integration | Peregrine TX (up to 4 transmitters) | Ocean (up to 5 transmitters) |
| Best for | The value all-rounder that lasts | A cheap rugged starter, or a premium dive watch |
Shearwater in short
Shearwater's Peregrine is the computer a lot of divers settle on: a large, clear colour screen, an intuitive two-button interface, and a Buhlmann algorithm with adjustable gradient factors so you can tune conservatism and extend bottom time as you gain experience. It recharges over USB, and it grows with you from Open Water into deeper recreational and light technical diving. The Peregrine TX adds air integration and a compass.
The trade-off versus a budget computer is price, and that it is rechargeable rather than user-replaceable, so you need to keep it charged on remote trips.
Suunto in short
Suunto's range is broad. The Zoop Novo is the classic beginner computer: cheap, rugged, a big four-button mono screen and a user-replaceable battery you can swap yourself, which is reassuring in remote dive towns. Its RGBM algorithm runs conservative, which is safe but cuts bottom time. At the other end, the Suunto Ocean is a premium colour-touchscreen dive watch with air integration for up to five transmitters, and sits well above the Peregrine on price. We could not confirm a current figure on Suunto's own store, so check it there rather than trusting a number from a comparison page.
If your budget is tight or you want a knockabout first computer with a swappable battery, the Zoop Novo is hard to beat; if you want a do-everything watch, the Ocean competes with the Peregrine TX and Garmin.
The honest take for travelling divers
For most nomad divers, the Peregrine is the sweet spot: the best interface, a flexible algorithm and one computer that lasts for years. Choose the Suunto Zoop Novo if you want the cheapest robust starter or value a user-replaceable battery, and the Suunto Ocean if you specifically want a premium dive watch. Whichever you pick, learn its algorithm and settings, and always dive within its limits and your training.
Which should you pick?
- If you want the best all-round computer that grows with you: Shearwater Peregrine (or the Peregrine TX for air integration).
- If you want the cheapest, most rugged starter with a user-replaceable battery: Suunto Zoop Novo.
- If you want a premium colour-touchscreen dive watch: Suunto Ocean, versus the Peregrine TX or a Garmin Descent.
- Whichever you choose, understand its algorithm and dive within its limits and your certification.
FAQ
Which is better for a beginner, Shearwater or Suunto?
Both work well. The Suunto Zoop Novo is the cheapest, most rugged starter, with a user-replaceable battery. The Shearwater Peregrine costs more but has a far nicer interface and a flexible algorithm, and it will last you from Open Water into advanced diving, so many divers buy it once and keep it.
What is the difference between the algorithms?
Shearwater uses a Buhlmann algorithm with adjustable gradient factors, so you can tune how conservative it is and extend bottom time as you learn. Suunto's RGBM tends to run more conservatively out of the box. Neither is unsafe; the difference is bottom time and how much control you have.
Is the Shearwater Peregrine worth it over a cheap Suunto?
For most divers who plan to keep diving, yes: the interface, colour screen and adjustable algorithm make it a computer you can use for years without upgrading. If you are on a tight budget or want a knockabout backup with a swappable battery, the Suunto Zoop Novo is the value pick.
