Recommended depths/times - Shutdowns!

Practice practice practice. And it wont happen again. I think the "fully open" crew are using equiment to cover up for a lack of skill

i usually have mine 3 hand turns (more like half turns open), then its second or 2 at most to shut them off.

Dill fulley open yes. 02 three (half) turns. I solved the free flow issue by taking the reg off the dilluient.

TDI standards state that a shutdown drill should be conducted no deeper than 30m.

END or Actual depth?

Is that a real question?

Do you wanna take just a wild stab in the dark on whether TDI would be fine with someone doing a valve drill at 65 metres just becuase they have 10/70 in their tins

EDIT: If you need a clue, read below

lol!

Glad I went thru all the DSAT courses then! My Instructor always had me do a complete gas shutdown drill at max depth of the courses, also many instant surprises to react to appropriately at depth. I did the same back to them on my instructor courses and trainer courses. Now I make sure that ALL my tec students can react in a timely manner to any emergency at depth or help their team mate -
as iuts my name on their cert card !

I was thinking of becoming a TDI Instructor as PADI have changed the rules on the CD contracts...maybe i will think again!

Out of interest, if I can do a smooth, faff free, shut down at 10m (which I can't by the way ) whilst maintaining good trim and a steady depth why would it be any harder, or a greater test of skill at 60m? Assuming I am breathing a suitable mix and so not narc'd off my face, I would have though it was much easier to maintain a steady depth at 60m?

A reasonable assistance indeed. Apart from this bit...

I'm pretty certain that the 'do all skills deep' mentality comes from deep air days.

I'm not sure I agree (sorry!), whilst the actions of doing a shut down at 50 metres may be exactly the same as doing at 6, arguably easier because of the reduced change in your bouyancy, your head will be telling you something completely different.

How many people can walk across a plank of wood that's lying flat on the ground without a stumble or issue. Put that same plank between two buildings a couple of stories up, would they be just as succesful or confident?

[Clare Gledhill]

The whole point is that it is 'harder' to do skills shallow and maintain buoyancy. Anyone can do a shutdown deep without losing buoyancy - yet I've seen many experienced divers lose it when trying the same thing in six metres or less.

In GUE training, the higher the level the more shallow the initial skills training. Doesn't mean that we don't do failures deep - of course we do to see how people get on with problem solving. But drills like S drills and Valve drills are perfected shallow.
