Dive Alaska can service all of your equipment needs from regulators to BCD's and dry suits. We are also a PSI tank inspection facility and can provide hydrostatic testing and visual inspections. Due to safety concerns, Dive Alaska will no longer fill or service aluminum cylinders which are manufactured from 6351 alloy. If you're not sure if this applies to your cylinder, please call for more details. We also no longer fill or service tanks with "J-valves". We believe that our customers shouldn't use life support equipment that is older than their car.
