I'm sure this has been said multiple times, but the whole AI thing looks like a solution for a problem that doesn't exist. What's the advantage over an SPG? You should already know your SAC rate, it will change over time but if you check it from your logs every so often you have a pretty good idea. The AI computer isn't changing it's deco algorithm as far as I know (please let me know if some company is believed to have made this adjustment). You should be doing a complete valve drill in including your deco tanks at the start of the dive, so you know your gas is in good shape. As far as I can tell a SPG is less of an entanglement hazard, far more reliable, and provides the same function as the AI transmitter. I'm fairly baffled as to why folks want them.
