These tanks were bought in 2003 and used for 4 total dives at about 30 min each just long enough to get certified to dive. They were hydro tested/inspected and then sat in my closet till now. They are still full of air but will require a new inspection before use. They are Luxfer aluminum 80 tanks that hold 3000 psi. Im asking $125/ tank but it is negotiable. Im aware it is $50/hydro test in anacortes. If you would like them tested prior to buying Ill pay for the test but if it passes the price is $150 each.
