Dive Computers

• Wrist dive computer or console? Wrist units wear like a watch and keep both hands free. Console pucks bolt onto your hose so everything—pressure gauge and computer—stays in one place.
• Need air integration? Add a wireless transmitter and the computer shows real-time tank pressure plus “minutes left,” so you surface with plenty of reserve.
• Easy readouts first. Big digits and backlighting matter more than fancy menus when you’re hovering at 50 ft.
• Battery style. Replaceable coin cells are handy in remote spots; USB or wireless charging is great for daily boat trips.
• Upgrade path. Most mid-level computers let you switch on nitrox or pair a transmitter later, so you can start simple and grow.

Tables guess; computers measure. A dive computer tracks your real-time depth and ascent speed, then tells you exactly when to surface or stop, so you spend more time exploring and less time doing math on the boat.

A wrist dive computer wears like a chunky watch, leaving your hands free for photos and inflator checks. Console units clip to your hose and keep pressure gauge + computer in one place—handy if you rent gear often. Pick the style that fits your routine.

An air-integrated computer pairs with a wireless tank transmitter and shows live pressure plus “minutes left.” It’s great for busy photographers and new divers who want one glance-at-all info, but a basic non-AI model works fine if you’re happy checking a separate SPG.

Many mid-range wrist units accept a transmitter upgrade whenever you’re ready. Entry-level “puck” models usually can’t, so look for “AI-ready” in the spec sheet if you think you’ll want the option.

Swap coin-cell batteries about once a year (or recharge after every dive trip for USB models), rinse in fresh water after each dive, and install free firmware updates as the maker releases them—usually once or twice a year for new features and bug fixes.
