How to choose your dive Computer

Find the ideal dive computer to track your parameters, manage gas mixes, and elevate your underwater safety.

A dive computer is an essential instrument for monitoring your depth, bottom time, and calculating decompression stops in real time. Easy to consult immediately on your wrist or console, it ensures every descent stays well within safe limits. All of Aqualung dive computers have 4 operating modes: Air, Nitrox, Gauge, Free Diving.

Wrist, built-in console, or wireless transmitter integration?

A dive computer alone isn't enough to dive without a pressure gauge. That’s why Aqualung offers the i330C built-in console, combining your computer and pressure gauge into a single, streamlined instrument.

If you prefer a wrist unit without a mechanical gauge console, choose a computer paired with a tank transmitter. Transmitters send real-time cylinder pressure directly to your display, giving you gas time remaining and tank data briefly. Aqualung’s i770R pairs seamlessly with up to four transmitters for comprehensive air management.

How many gas mixes do you plan to dive?

Select your dive computer based on the gas configurations you intend to use. All Aqualung models support multi-gas switching for at least two mixes:

Rechargeable battery vs. user-changeable battery?

Power management is key when traveling or planning back-to-back dive days:

DiverLog+: Easy setup & digital logbook

Each Aqualung dive computer syncs with the DiverLog+ mobile app via cable or Bluetooth® Smart wireless connectivity. DiverLog+ gives you full remote control over your computer settings directly from your smartphone. Easily adjust Nitrox mixes, user displays, alarms, and display units before your dive, then view, analyze, and share your detailed digital logbook after stepping back on shore.
