Hand Signals: psi and numbers (new section proposal)

It's been awhile since I last dived, but I recall learning hand signals for numbers. These were often used in response to "How much air do you have?" or "What is your psi?" or even in reference to time or depth. Normally, I would create a section and just put the "Please expand" template in it, but I was unsure of where to place the section. I figured I would make a post here and see what you guys thought.

@Zoms101: The signal I normally use to ask "how much air do you have?" is to show the diver in question my air gauge – the expectation being that they will show you their gauge, which removes the possibility for miscommunication of numbers. However, like your experience, I don't have a reliable source for that. If you know of a reliable source that illustrates hand signals for numbers, then we could use it.

@RexxS: I assume one could use ASL numbers. I found a link to a .pdf for hand signals by the New England Aquatic Dive Club[1] and a forum discussing standardized hand signals for numbers[2]. Regardless, I think this topic should be covered somewhere in the article, even if the ASL method is just mentioned in passing. Zoms101 (talk) 15:15, 31 October 2018 (UTC)
