The Archimedes Principle. It's Buoyancy.

What makes lift bags work? The great Greek scientist Archimedes discovered the property: buoyancy. According to Archimedes Principle, "any body wholly or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced." Because of this law of physics, a SUBSALVE USA bag that weighs only 26 lbs. can raise a ton from the ocean bottom.

Subsalve expands upon Archimedes and creates the very best tools to lift something from the far depths of the ocean to the top. We design our bags to harness buoyancy in ways that are efficient, effective and fit your needs.

Designed for Buoyancy Control

Our liftbags' unique designs also give you flexibility in manipulating buoyancy by utilizing our Plunger Dump Valve or V4 buoyancy control hose. So you can more control over where your object is positioned in the water on a moment-to-moment basis, if necessary.

Buoyancy gives you the lift--SUBSALVE GIVES YOU THE BAG.
