those inflateable floats were hole thru middle taylor bumpers. They were just big enough for a 4'' dredge.
when over inflated they "footballed" and rubbed the U shape support so had limits to weight supported.. Good for a 4 inch with air and had plenty of reserve boyancy.
The whole thing was nearly indestrible and rolled to the water just great.
The bigger dredge had custom made semi ridgit foam floats that were coated to 3/8 '' with the same stuff that is used to make 'Pipe line pigs" .. Real tough.. road proof. Could be scalled up to any size but cost a lot. The twin engine dredge had so much extra floatation that with the sluice full , two people could ride dry down stream to new locations.
Cost to much for the adverage prospecter so never got into making them for sale, just two, 4'' and 6'' (mine).
I could make a new one from scratch but it would be ??? $4k-$5k.
Had twin 6.5's hondas and twin Goldivers pumps and twin cylinder air with either a custom twin input jet or a gold divers jet.
Over and under sluice and a rubber custom flair. The whole thing could be folded in two and rolled 15 mph down a dirt road or left un folded and still pulled up a steep bank rolling over small bolders bushes whatever and not needing disasembly.
Was nice,, oh yea... got gold too LOL..
