One button runs it all
Aqualung built the i100 around simple one-button navigation. A single press brings up your last dive data, and History mode records up to 24 dives.
i100
One button, simple menus, made for new divers
Aqualung made the i100 for new divers: an entry-level computer with the essential functions and simple one-button navigation. Choose from four operating modes and manage two gases. Change the battery yourself and it keeps all your settings and calculations. Audible alarms come with a high-visibility LED warning light, and it switches on when it touches water.

Highlights
Four modes, two gases
Choose Air, Nitrox, Gauge or Free Dive, and mix up to two nitrox gases, from 21% to 100% O₂, with a max PO2 of 1.1 to 1.6. The Z+ algorithm has gradient factors and an optional deep stop with a countdown timer. It adjusts for altitude automatically and lets you select salt or fresh water.
Alarms you hear and see, switches on in the water
Audible alarms come with a high-visibility LED warning light, and the computer switches on when it touches water.
Change the battery yourself, keep your settings
It runs on a standard battery you can change yourself, and it keeps all your settings and calculations while you swap it.
No Bluetooth: a download cable, sold separately
The i100 has no Bluetooth. Data comes off it through a download cable, sold separately, and software updates need the same optional cable.
Who it is for
Great for
- New divers: Aqualung made the i100 for them
- Divers who want the simplest controls: one button
- Divers who use air and nitrox: two gases, 21–100% O₂
- Divers who do both scuba and freediving: Free Dive mode is on the same computer
Maybe not for
- Divers who want a backlight or Bluetooth to their phone: the i100 has neither; look at the i300C, which Aqualung calls great for new and experienced divers alike and which has both
- Divers who want up to three gases or console mounting: the i100 takes two gases and is wrist only, while the i300C takes up to three and can go in a console
- Divers who need a built-in compass: Aqualung lists none for the i100

FAQ
i100 or i300C?
Both have four modes (Air, Nitrox, Gauge, Free Dive) and a battery you change yourself. The i100 is Aqualung's entry-level model for new divers: one button, two gases, no backlight, no Bluetooth, wrist only. The i300C, which Aqualung calls great for new and experienced divers alike, has two buttons, up to three gases, a backlight, Bluetooth 4.0 and console mounting. For a colour screen and a rechargeable battery there is the i330R, which Aqualung aims at advanced divers who travel. Not sure? Ask us on LINE.
Does it have a backlight?
No. Aqualung lists no backlight for the i100. If you want one, the i300C has a built-in backlight.
Does it connect to my phone?
No. The i100 has no Bluetooth; data and software updates go through a download cable, sold separately. If you want your dives on your phone, the i300C sends them over Bluetooth 4.0 to the Diver Log+ app.
