Believe it or not, PSUBers, a simple clip (like the one I use on my keys to keep from forgetting my cell
phone in restaurants - just a tiny thing) is what hung up the Johnson-Sea Link (archives).

So, some sort of release -30lb test line, Velcro, etc. is definitely called for.  Cheaper than a camera or
periscope.
