Crack bottle DSMB's are popular amongst UK tech divers for good reason. My personal rig of choice is a 2.5m with crack bottle attached to a 100m Kent Tooling reel.
Skippers usually mandate that a team deploy a bag when leaving a wreck / site, so that the boat can track their progress in current. You can travel a long way during a 45 minute ascent and with choppy seas you want a big old bag to stay visible. Frankly a dainty little 3 footer ain't gonna cut it.
With a crack bottle to fully inflate a high volume bag and hefty reel / handle to hang from, I know my bag will stand proud and the boat will be waiting for me when I surface a mile away from the drop off.
To the OP, Kent Tooling also sell replacement crack bottles. Not sure if they're open due to current restrictions but worth a try.
