Technical diving skills- S-drill

Would be much better to have someone else film this to better show the stowing of the hose around the canister light battery. An S-drill is a check to ensure that your longhose is deployable. It should be done after getting into your gear, then again on the surface, and once more at the beginning of the dive when in the prone position, normally at 6m, before you commit to descending. In-water, it's a very quick check that everyone can do at the same time. Common errors that should be detected before you get in the water include trapping the longhose under the drysuit hose, or having the longhose twisted around the short-hose. I've even seen the long-hose stuck underneath the waist webbing before people realise what they have done. Re-doing the S-drill in the water is a final check when in the diving position and ready to go. Any problems can be dealt with easily, rather than when someone is genuinely low or out of gas.
