I saw a demonstration of this wet sub on tv but I missed the name of it or if it was even commercially available and I am hoping some knowledgeable person on this site can help. You sat in this vehicle like sitting in a chair. It had no cover for the body but had a bubble for the head that had an air pocket for breathing, air being supplied by compressed air. It was yellow, had a max depth of 30 feet and a max dive time of one hour. Please drop me an email with any guesses as to the name, thank you for all your help.
