Lift Bag


Lift bags are used to float heavy objects to the surface.  Lift bags for sale seem flimsy and overpriced, so I sewed one from heavy weight cloth.  This one is also designed differently, since a rising objects's momentum can let the bag break the surface, topple over, spill some air, then the object starts sinking, which may collide with an ascending diver.  Am planning to go diving on 30 December to see how well this works.
