I was blown away by the comfort and stability of the Quantum SLS BCD. During long dives, I didn’t experience any fatigue or discomfort. However, I did notice that the weight pockets could be a tad larger.

One major drawback is the lack of smart features. To make it more appealing to tech-savvy divers, would it be possible to integrate a smart BCD system, such as a dive log or navigation?
