Aqualung i770R Dive Computer
Aqualung i770R dive computer
The i770R is the sensible middle of the wrist computer market. Full-colour TFT screen, rechargeable battery, Bluetooth, a proper tilt-compensated compass and four operating modes, without the price of a flagship or the compromises of an entry-level unit.
What sells it in the shop is the screen and the three buttons. The display is genuinely bright, and three physical buttons work in thick gloves in a way touchscreens still do not. For UK diving that combination matters more than most feature lists.
It sits in the middle of our dive computers range, and it is the one we recommend to divers who want multi-gas capability without paying for mapping and smartwatch features they will never use.

Three buttons beat a touchscreen in cold water
Touchscreen computers are excellent on the surface and unreliable through 5mm gloves. If your diving is mostly UK and mostly cold, a physical-button computer like the i770R will frustrate you far less than a touchscreen at twice the price.
Why divers choose the i770R
The screen does what it claims
High-contrast colour TFT that stays readable in bright sun and in green water. Dive computers live or die on whether you can read them without thinking, and this one you can.
Multi-gas without a technical price tag
Four operating modes and support for multiple gas mixes means the i770R will follow you from open water through nitrox and into early technical training. That is a lot of headroom at this price.
A compass you will actually use
A 3-axis full-tilt compass holds an accurate heading even when the computer is not level, which is the entire point. Tilt-limited compasses require you to stop and level out, which is exactly when you lose the line.
Serviced and set up in-house
Like every dive computer we sell, the i770R can be serviced in-house at our UK dive centre. We will set the gas mixes, conservatism and alarms with you rather than handing over a boxed unit.
Features that matter underwater
Rechargeable lithium battery
No battery changes and no flood risk from a battery hatch. The trade is that you need to remember the charger on a trip, which is a different discipline to carrying a spare cell.
Adjustable screen brightness
Turn it down when you do not need maximum output and the battery lasts noticeably longer. On a multi-day trip this is the setting that decides whether you charge nightly.
Bluetooth and DiverLog+
Logs transfer wirelessly to the free DiverLog+ app, where you can review profiles, add photos and dive sites, and share them. Settings can also be managed from the phone, which is far easier than doing it on three buttons.
Three-button navigation
Simple menu structure driven by three physical buttons. Nothing to learn beyond the first dive, and nothing that stops working because your gloves are too thick.
Remember the charger
A rechargeable computer with a forgotten charger is a paperweight by day three of a liveaboard. If that scenario worries you, a computer running on a user-replaceable AA, like a Shearwater Perdix, is the safer choice for remote trips.
Who the i770R is for
- Divers upgrading from a basic first computer
- Anyone who wants multi-gas capability without flagship pricing
- UK divers who want physical buttons rather than a touchscreen
- Divers who want a proper compass on their wrist
- Aqualung owners keeping their kit within one ecosystem
Who it may not be for: divers who want a computer that doubles as an everyday smartwatch, and expedition divers who cannot rely on charging. For the first, look at a Garmin Descent. For the second, a Shearwater on AA cells.

Frequently asked questions
Does the Aqualung i770R support nitrox and multiple gases?
Yes. It has four operating modes with multiple gas capability, so it covers air, nitrox and gas switching rather than being limited to a single mix.
Does the i770R have a compass?
Yes, a 3-axis full-tilt digital compass. Full-tilt means it holds an accurate heading without needing to be held level, which is what makes it usable mid-dive.
How is dive data transferred from the i770R?
Over Bluetooth to the free DiverLog+ app, where you can review profiles, add sites and photos, and change settings from your phone.
Is the i770R battery replaceable?
It uses a rechargeable lithium battery rather than a user-replaceable cell. Remember the charger on trips, or choose a computer running on AA cells if you dive somewhere power is unreliable.
Is the i770R usable with thick gloves?
Yes, and that is a genuine advantage over touchscreen computers. The three physical buttons work in cold-water gloves where touchscreens become unreliable.
