I've seen this product advertised in a few magazines and I decided to take a look at the Aqualung website to get a little better look at it. They call it the S.O.S. "surface observation signal". It looks like a really handy product. It replaces the lower dump valve on Seaquest BCD's, and eliminates the need to have to manually blow up your surface signaling device. I was courious if any on here has one and if so how do you like it?
