JCKCSYCMD:When not diving from a boat, have used the good old inner tube concept for years. I did weave together 2" webbing for a 4 point soft "tuge frame". Webbing is also yellow to increase visibility, in addition to flags. To this is a heavy mesh bag inside, and 1" webs going down to 5 foot intersection beneath tube. This puts a load on it so it doesn't get knocked over by wave, boat wakes, or wind.....[message truncated]
Would you be able to post (or send) a couple pics of this setup? Sounds great.
(Or perhaps next time I'm in Grosse Pointe visiting the family, I'll have to stop by! )
