    The thumb-up, index finger extended signal is generally used to indicate
DIRECTION to the exit or the ascent line.  It can be prefaced with the
question sign to make it an inquiry.  The upside down stirring sign, as
explained by Mr. Pelstring, is what is used to turn the dive when there are
no aggravating circumstances provoking the "turn".  Pointing to the SPG
clarifies the reason for the turn.  The rate of exit will be without undue
urgency with this signal.  If there is a need to exit the cave/wreck with a
degree of urgency, or at least to avoid "sightseeing" on the way out,  the
thumb gets thrown.  Throwing the thumb during exit after the dive is turned
with the upside-down stirring signal conveys a need for a more urgent exit
than what is
currently taking place, a.k.a. "You're going too damn slow."  It's all about
being clear and concise.

Dive safe,

Duane
