Dive Computers
A dive computer tracks your depth and time underwater and calculates how long you can safely stay down, which takes the guesswork out of no-decompression limits. Our collection includes Garmin Descent and Shearwater models, along with dive computers from Mares and Ratio.
Watch-style computers are small enough to wear every day and easy to travel with, and many divers use one as their only computer. Larger-screen computers like the Shearwater Perdix and Petrel or the Ratio iX3M are easier to read in low visibility, and technical divers tend to favor them. If you want tank pressure on your wrist, look for an air-integrated model that pairs with a wireless transmitter.
Not sure where to start? Our SSI instructors can explain how each computer handles nitrox and dive logging before you buy. Browse watch-style dive computers, larger-screen dive computers or analog gauges and consoles.

Dive Computer Buying & Setup Guide

- Check display readability. Look for bright, clear screens with easy-to-read data, especially for low-visibility or deeper dives.
- Consider battery type and charging. Some models use replaceable batteries, while others are rechargeable, which may be more convenient for frequent divers.
