Hand signals can be interesting. It kind of makes sense that signals for sea life vary, but every dive shop so far has told us to use different signals for showing the PSI remaining. (OK, that's only 4 dive shops, but still...)
Funny story - when diving in Cozumel, the signal I had learned for 700 PSI (two fingers, sideways) was what they used for 200 PSI. I really freaked out the DM. He went into emergency rescue mode, had us start to ascend, signalled "out of air", deflated my BCD, and had his octo ready to go before he looked at my console and saw that I still had 700 PSI remaining. Then he did a facepalm, and we finished our ascent/safety stop normally. I apologized profusely on the surface, of course. How embarrassing.
