Aqualung I300C Dive Computer

Black Blue

£165.95 £237.00
Manufacturers Description


The AquaLung I300C Computer is an upgraded version of the i300 that now has Bluetooth Smart technology built in, making it even simpler to use.  Bluetooth means you can connect the i300c to your smart device to download your logs to the DiverLog app wirelessly.


Operating Modes

Whether you dive on Air, Nitrox or you're Freediving the i300 computer will work for you with one of it's modes. Dive mode is for Air and Nitrox that you can change up-to 50% O2. Gauge mode acts as a simple depth gauge and bottom timer but won't record your decompression data. Freedive mode is for snorkellers and will measure your depth frequently but will not alarm when you ascend quickly.


User Changeable Battery

You no longer need to take your dive computer into the dive centre to get the battery changed. Keep a spare battery with you when you travel to avoid disappointment and you can change the battery over yourself in-between dives if you need to as the i300 will maintain settings and calculations between battery changes.
