Lift and Marker bags have come a long ways since the days of their use as a means to float an object. In fact, many boat operators insist on you having a Lift Bag on every dive. The need to mark your position by attaching a Lift Bag to your REEL and sending it the surface can be of vital importance, so whether you choose to pop a bag from a deep wreck dive, want the boat to know your location as you float down the reef on a lazy drift dive, or need some lift to get that treasure to the surface, Dive Rite has the Marker/Lift bag to make sure you get the job done.
