AQUA LUNG i300 Dive Computer

5 18

The AquaLung i300 is a wrist mounted dive computer with high quality materials and algorithms at an affordable price. The large display is combined with a low profile design for an easy-to-read streamlined computer that won’t stand out and get stuck on straps.

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.

    Is this model an upgrade to i200? I mean, is it better and with more functionality?

    I just got it but it is quite annoying that the strap is way too long. I guess i can go cut it already and 2nd the data cable is NOT included standard, which cost me 60€ more if i want to review dives on pc or mac, what a ripoff! How can these cons be missed in a review?
