I carry a 100 lb Carter lift bag on every dive bungeed to the right hand tank. Anchors and other heavy items found on the bottom get sent up with the bag carabinered to the flag line if I am the unlucky person dragging it, or sent up clipped to a reef scuba saftey reel if I'm not dragging the flag.
It also comes in very handy for shooting an up line on deep low viz dives if for some reason we don't end the dive at the anchor line.
