On the dive last friday (wreck dive) - one of the divers had a problem with the BCD strap that holds the tank in place as it wasn't set up properly (it was her BCD not the LDS').
The DM tried to sort this out (with assistance from me as well ) and had to take his BCD off to check the buckle on his (and how the webbing was put through the buckle), so that he could do the webbing and buckle on the divers correctly.
I haven't taken off my BCD underwater since I did my OW. But surely the skills we learn in the OW course should be practiced on a regular or semi-regular basis??!!

So this begs the question - how often do YOU check your skills???
