The plastic housing at the lense leaks badly at even snorkel depth. It would flood the camera at SCUBA depth pressure. The big o-ring for the clamshell housing seems to work, at least at snorkeling depths. Camera itself takes good pictures and is easy to use.
I really liked the fish flips ID bracelet. The wrist band kept the pictures handy for easy access and I could see the pictures and big print under water. Not only did I use it scuba diving, but my daughter enjoyed it while snorkeling.
Excellent for snorkeling, good exhalation valve. Fine for lap swimming in the pool, good visibility without distortion in the one piece lens. Good fit.
I purchased a pIe of the Mares booties and they fit well in a smaller size than I usually wear . Extremely comfortable both with and without fins. Good quality and good value.
