Choose a dive computer for the type of diving you are trained to do and the information you need to read clearly underwater. A long feature list is less useful than a display and controls you can operate confidently.
Display and controls
Compare screen size, contrast, backlight and button layout. Think about how the display will look in lower visibility and whether you can operate it with the gloves you use. Wrist-mounted and console-mounted formats serve different preferences.
Air, nitrox and other modes
Check the exact model’s supported gases, oxygen limits and dive modes. Gas switching, freedive modes and technical functions vary between computers. Features do not replace the training needed to use them. Read the manual and learn the computer’s settings before diving.
Air integration and accessories
If you want tank-pressure information on the screen, check whether the computer supports air integration and whether a compatible transmitter is included. A computer-only price should not be assumed to include a tank pod, charging cable or alternative strap.
Battery, logs and ownership
- Compare rechargeable and replaceable-battery designs.
- Check charging or battery replacement instructions.
- Check logbook connection requirements and phone compatibility with the manufacturer.
- Confirm the contents of the exact package or variation you select.
Use the computer consistently with your training and manufacturer instructions. Do not share a computer between divers during a dive profile or use another diver’s reading as your own.
