We said it before, and it is worth saying again – a DSMB should be one safety tool that accompanies you on every ocean dive. But it is all well and good having a DSMB, but how are you sending it to the surface? Scuba Diver Editor-in-Chief Mark Evans has a look at the pros and cons of reels and spools.
no mention of the `reels line snagging leaving you with 2 choices, let go of it or be dragged to the surface
I have actually seen people with a badly wound spool having it jam and instead of simply releasing their grip holding on to it and heading skyward, so it is not just reels.
We plan a more in-depth video on launching DSMBs with underwater video when we can get to a suitable location to shoot and we will be sure to stress that then.
