What our customers are saying about Aqualung I100 Computer dive computer

Perfect recreational diving

2025/07/26

julien

A simple and comprehensive product for recreational and even technical nitrox diving at a reasonable price. Easy to use with a single button that doesn't get stuck over time. The battery can be easily changed by the user. It's a shame that this simple and effective product is being replaced by complex products that don't add anything to the enjoyment of recreational diving.
