If you do as often as we leave the sea and underwater filming much is a wrist strap already useful. We often underestimate the depth of the water, and then once the camcorder slips of hand floats the loop upwards. I myself do not consider myself the strap around your hand but use it simply as a buoy. The quality is great, too, there were no cheap materials and substances used. I would definitely buy again, if I get my lost.
