I recently asked for recommendations on a float tube for halibut and bass fishing. Thanks to everybody for the input. I will probably buy one this week. ...but while looking around on the internet, I ran accross a product that turns a basic car-tire innertube into a fishing tube. It is called the Deschutes Float Tube Converter.

I am curious, has anybody ever had a puncture in a float tube while fishing? Is sinking really a big concern? Does it really ever happen? The idea of a $29 float tube converter is attractive, but maybe there is a reason the $150 float tube is covered in that bullet proof stuff -- maybe a basic innertube in the ocean isn't really safe??? Anybody have an opinion?
