NOTE: Various sizes available, each priced separately . Want to fish but don't have a boat ? Jump onto a large tube and laze in the lake or river , either still-fishing or moving with the current or breeze. OR BUILD A LIGHT-WEIGHT ( easy to move and store ) RAFT. I have tractor tubes that inflate between 4 1/2 and 6 - 7 feet in diameter that will do it all , including being towed behind a boat, smowmobile, or ATV . Or just slide down a snow-covered hill . These have quick deflate valves for when you're done for the season , are very heavy duty rubber ( NOT PLASTIC ) and don't leak. Priced $40 to 85 depending on the size you want. I ALSO have some about 3 ft in diameter , also heavy duty rubber, for $25 to 35.
