Hand Signal: Turn the Dive

[mr_v]

Turn around: Finger making tight circles pointing up or down. Pointing down may be easier in some gear configs.

Emergency (surface): Thumb up. Move!

Non-emergency exit in a specific direction: Thumb up + index finger pointing to the direction.

a and b are the clutch phrases, but I am guessing you don't understand the magnitude of them.

Regarding a You can turn around (at turn pressure even) and go back closer to the entrance, recalculate gas, and go down another passage with some of the remaining. If you want to reserve the option to make a detour on the way back you simply "turn around" which is the finger twirling in the air. So choice 3

Regarding b if you are going to a new exit on a traverse its thumb up and finger pointing ahead at the new exit. Choice 2

If you are turning around and committing to exit it's the thumb. Choice 1

They each have different utility depending on the decision at hand. Prosser and Grey's "Cave Diving Communication" published by the NSS explains them all.

Good stuff, do you have a copy of that PDF that's not on Scribe? I've not done much hub/spoke/traverse cave diving...yet, mine's mostly been one way in, one way out (other than some side passages) so good to get these perspectives.

Thanks
