Can lights and valve drills

[astrofunk]

Good question. I was taught to breathe down both regs before switching either way.

Me too. But I suppose purging it down would work just as well -- that never occurred to me.

Huh -- it seems like most folks are already back on their primary when working with the left post.

How do you know you've turned your left post valve all the way, if you don't breathe down your backup?

You purge down the backup regulator.

Correct, this was left out from amascuba's list. Other than that, nice writeup.

The list has been modified to add the step of purging the backup regulator now.

Ha -- isn't that the great thing about cyber diving?

Writing out 26 steps is WAY hard than just... doing a valve drill.

The drill has been changed - it's specified somewhere at GUE site.

Here is the drill as I was taught

1. Signal your team that you are about to start a valve drill.
2. Purge your backup regulator to be sure that your left post is on.
3. With the light in your left hand, start signaling your team mates by moving the light side to side.
4. Turn off your right post.
5. Breath down the primary regulator.
6. Switch to backup regulator.
7. Stop signaling with your light.
8. Clip the primary regulator off to your right d-ring.
9. Give an OK signal.
10. Turn the right post back on.
11. Unclip primary regulator from the right post.
12. Purge the primary regulator to verify that the right post is turned on.
13. Switch back to the primary regulator.
14. With the light in your left hand, start signaling your team mates by moving the light side to side.
15. Turn the isolator off.
16. Stop signaling with your light.
17. Give an OK signal.
18. Turn the isolator back on.
19. With your right hand, grab the light head and remove it from your left hand.
20. With the light in your right hand, start signaling your team mates by moving the light side to side.
21. Turn off the left post.
22. Purge backup regulator to be sure that the left post is turned off.
23. Stop signaling with your light.
24. Give an OK signal.
25. Turn on the left post.
26. Purge your backup regulator to be sure the left post is back on.
27. Give an OK signal.

I see several issues with this as written that don't jive with what was taught in my GUE class.

One thing is step 7 - you have top stop signalling before this point as it is impossible to keep signalling while putting the back-up reg in your mouth as they both use the left hand.

In fundies we were not taught all those OK signals between each step (the ones in RED) - just the one at the end (in BLUE)
Also keep in mind that a flow check is required before you give that final OK.


Here goes a demo from you tube (not me).

Ha -- this is a bit off topic, but I couldn't help noticing the change from SADDDDD to GUE EDGE in that same training memo.

Does it crack anyone else up that they built a name-check right into the pre-dive procedures?

Jason I must be falling down on my game.
