Aqua Lung

I770R Dive Computer

Regular price £620.00 £620.00 Sale In Stock

Brand: Aqua Lung

Model: I770R Dive Computer

SKU: 76266-1

Please note: This item cannot be shipped outside the European Union - learn more

The Aqua Lung i770R Dive Computer is a colour screen rechargeable dive computer with a large screen so you can see everything at a glance. Colour-coded information means that your eyes are drawn to the information you need to know.  The i770 is rechargeable so you don't have to worry about changing the battery or it running out unexpectedly, just plug it in every so often to keep the battery topped up.



 The i770 is made for any diver but more aimed at the recreational travelling diver who appreciates a bright, easy to understand computer.  Rechargeable means that it doesn't require much maintenance or the yearly journey to the dive centre to have the battery changed. 


The i770R will connect to the Aqualung Transmitter and can be charged by mostany modern powered USB adaptor like the one for your smartphone or tablet so you only need to bring one charger on holiday with you. 


 To use the i770R to the full a wireless transmitter will talk to your computer and keep an eye on your gas consumption during your dive.  If you start to run low it will let you know unlike an analogue SPG.

We recommend 


 A similar sized, colour screen dive computer to consider would be the Suunto EON Core or more advanced EON Steel or the Scubapro G2 Range.  If you're thinking about moving onto more advanced technical diving then look at the Shearwater Perdix or Petrel.

Aqua Lung I770R Dive Computer - Features

FeatureProduct Specification
Air Integration
A dive computer with air integration allows the diver to view the current cylinder pressure on the dive computer display. Some models also display breathing rates. Air integration can be achieved through either a high pressure hose attachment or by using a wireless transmitter.Close.
x4 Wireless (not included)
The built in algorithm that calculates your NDL and recommends when it's safe to ascend.Close.
Apnea Mode
A collection of features developed for free-divers and snorkellers that records how deep you are, how deep you have been and how long you can hold your breath. Some computers include a faster sampling rate, specialized alarms and warnings and specific logbook for apnea.Close.
Computer Style
The format denotes the style of the computer, whether it is a standard wrist sized unit with large easy to read display, a smaller watch sized unit which can be worn for every occasion but still packs in all the same features or a console mounted unit which are available with or without air hose integration.Close.
A PC Interface alllows divers to download previous dive information and profiles for viewing and analysis on a PC or smart device via an app. Depending on the model of dive computer this can include depths, times, alerts, breathing rates, temperatures, etc.Close.
Display Type
The type of screen affects what and how information can be displayed on a dive computer screen. The simplest is a segment display that builds up characters using pieces of a fixed screen like a digital wrist watch. This is cost effective but limits the use of complex details. A partial dot matrix screen stills uses a section of segment display for numbers but also has a section of tightly group squares that allow for text or graphs to be shown on the screen. A full dot matrix screen completely does away with the segment section of the screen to give full use of the display. Colour LCD screens use the same technology found in TVs to provide a high resolution colour display that gives very clear, vibrant dive information. The technology is more expensive but raises the computer to a new level. OLED screens use a display of tiny LEDs that are very efficient and super sharp. The screen doesn't require a power hungry backlight and can still be seen in very low visibility.Close.
Gas Nitrox
A Nitrox or EAN (Enriched Air Nitrox) compatible dive computer allows divers to benefit from the advantages of diving with an enriched oxygen gas mix including extended dive time without incurring mandatory decompression stops during the ascent.Close.
21 to 100
Gas Trimix
A trimix compatible dive computer allows a suitably qualified diver to take advantage of the benefits of a Trimix gas consisting of oxygen, helium and nitrogen. Advantages include extended range diving and reduced narcosis effectsClose.
Integrated Compass
An integrated compass helps to reduce additional pieces of equipment that need to be carried. Some console computers are equipped with a standard magnetic compass. A number of computers now feature an electronic compass that is built into the unit itself and operated through the menu system. The electronic compass shows the magnetic North all over the planet by recalibrating the compass for your current location.Close.
Multiple Gases
Gas switching allows divers to use more than one gas mix whilst diving. For example, it allows a diver to switch from main breathing gas to an enriched oxygen mix to decompress faster when ascending.Close.
Rebreather Mode
A dedicated Closed-Circuit-Rebreather Mode that, depending on the computer, you can adjust and plan high and low setpoints, open circuit bailoutsand other features for diving with a rebreatherClose.
User Changeable Battery
Modern dive computers allow divers to safely change the battery themselves with minimal risk of damage through flooding due to incorrect installation. The logbook and memory of previous dives are typically saved during the battery change. Watch sized dive computers typically still have to be returned to an authorised dealer to have their batteries change as special tools and usually needed to open the body.Close.

Excellent Watch and easy use

Its an excellent watch, it already comes with a screen protector on it so need to purchase as screen protector. The mobile app is very excellent, it syncs and gives the latest updates. The screen doesn't was out in the bright sun like the i450t. Numbers are clear and visible to anyone using it. Best part is no need to worry about battery while connecting the computer to an aqua lung transmitter

The Perfect Recreational Dive Watch

I was in the market for a new dive watch when I came across this wonderful piece of kit.

The screen on this dive computer is beautifully bright and colourful and can be adjusted to suit your own preferences, even with the ability to auto dim after a period of time when you are beneath the surface. With only 3 buttons to use the menus are very simple to navigate and its extremly easy to change any settings that you require. As a recreational diver all the information that you would possiblly need can be displayed clearly on the main screen, this includes depth, dive time, no deco time, air time remaining, dive time, gas pressure when used with a compatible transmitter, gas mixture & max depth with current gas mix if using nitrox. In addition to the said information there are 2 colourful bars at each side of the watch screen, one displays nitogen tissue loading and the other being ascent rate. This works by filling the compartments from green to amber to red and then all flashing when values have been exceeded.

All dives are logged on the computer and can be offloaded to the Diverlog + app which is very useful. This is done with bluetooth which works very well. It is worth noting that the app can also be used to change the watch settings and update the firmware.

There is also a useful compass that can be accessed easily from the main dive screen from which you can mark headings etc.

Highly recommended watch for recreational divers.
