Used the watch on a first dive in the ocean. Worked like a charm and was able to perform accurate timing to pre-planned depths. for the cost, all divers show have this as a back-up especially for gauge mode.

This is all you need for free diving. I just used it off Palm Beach in a free diving course. It automatically becomes a depth gauge and timer when you submerge. Later see the results of each time you submerged how deep and for how long. I don't know what fancy free diving computers are supposed...

Failed to be waterproof on my dives in Hawaii. I didn't even drop 20 ft. and the bezel leaked causing short-circuiting and damaged LCD readout. It went completely blank when I surfaced for my breath-up. I dried it out overnight and tried it again... failed in 5 feet of water. See LCD damage.
