Review on Wrist Mount Compass for Ocean Exploration by Tyler Blake

Used on one dive and performing well. The fluorescent back worked great. I used it during a night dive and only charged it once during a dive, but I never charged it properly, maybe 10 seconds. A longer initial charge can extend the service life. The rotating bezel moves easily and the rubber line is great. My only complaint is that you have to hold your hand to use it. For those who find it difficult to stay on course without constantly looking at the compass, it can be difficult to keep your hand up. It worked well for me and I will continue to use it.
