"PADI" does not teach hand signals for pressure. An instructor teaches those, so they vary a lot.My cert is PADI and what they taught was the 1-5 digit was fingers up, 6-9 digits was fingers sideways or down.

fist for 50 rubbish
use what you want I don't give a flying F
Yanno, if I were diving a site where I needed the use of both hands for a significant part of the dive, I'd probably leave my camera topside. However, most sites I dive don't require the use of both hands during most of the dive to survive, so I usually take my camera with me.I'd like to see you with your camera on the sites we dive, where one hand is needed to hold on to avoid the down currents.
We were taught 1 finger per 100 psi. We still use that. No ambiguity. A quick flash is always 5 fingers, the last flash is held for several seconds to allow proper comprehension. You only need to actually see the last signal. Flash Flash Flash 3 fingers is 1800. I can be happy with any system that uses only 1 hand and minimal brain power.
The half tank T system sucks...It is very inadequate. Not granular enough.
On our last dive trip the DM introduced the (new to us) T for half tank (1500 psi) signal. He was very clear that we needed to signal him when we hit half tank. He did not discuss any other means of signaling our air OR any other expectations that we needed to communicate our current air pressure to him. T or nothing...Ok? Your rules, works for us. Let's dive!
After a few dives of him pointing at his pressure gauges, giving me the OK signal and me shrugging and returning the OK signal he got a little pissed. After one dive back on the boat he came up to me and asked to see my pressure gauge. 1600 psi. Stupid system...
They were filling al80s to 3300 or 3400 most days...
Same for bar, just one less zero (10, not 100. 50, not 500)This is of course PSI, not Bar.
Hopefully you don't need to show 200 very often!The only ambiguous signal is for pressures in the 2000's and 200's, but the correct pressure can be determined by dive context.
