Perhaps I am more critical of this practice because bottom time at depth is so important. If you do a deep dive your bottom time is limited by gas and your tolerance of deco. As a result you can end up with 20min -30 min bottom times on a dive that just cost you £50.00 in gas, £35 for the boat and £10 in petrol.
Fafing about finding a tie off spot and actualy tieing off is a time consuming and there for bad thing. also a cock up would cause extra bottom time which = extra deco comitment.
If I bag oof and it goes tits up I let go the reel and go to first stop depth and go to back up. That is the safest thing to do on a deep dive. All this getting toed to the surface nonsence is for people who think there £100.00 worth of equipment is worth the trip in the helecopter.
I made that mistake once but never again.
So all in all horses for courses. If your happy with the system and not doing extended bottom times cool. If you are then mid water / botom deployment of DSMB is IMHO esential skill.
