From one-button colour units to AMOLED tech watches you can wear every day — the most flexible category for most divers.
Wrist and watch-style computers are where most divers land: streamlined, easy to travel with, and available at every level from simple recreational units to full trimix watches.
If you're unsure how much computer you need, start with our best picks or the buying guide. Prices below open a live Amazon or eBay search.
The reviews and guides here are editorial information to help you compare models — they are not dive training or a substitute for proper certification. Always dive within the limits of your training, follow your computer's ascent rate and stops, and get formal instruction before technical, nitrox, trimix or rebreather diving.
Sister sites covering the rest of the water — same honest, spec-first approach.
Find fish before you dive a spot — sonar units, transducers and castable finders.
Outfit the dive boat — chartplotters, VHF, deck hardware and safety kit.
For the topside angler — spinning reels, rods, line and terminal tackle.
