Scuba Signals and Air Management

scuba signalsBy now you are all familiar with the basic scuba signals and some of you have probably even invented your own scuba signals for a special creature like that very big shark that is behind you. And I know you know the signals for out of air, but how about low on air and how do we tell the dive master how much air we have left in our tanks?

Flashing fingers to signal our air supply just confuses me and most dive masters, because I can’t count that fast. There is an independent instructor that likes to have his students signal with fingers on their chest with how much air they have left.  The problem with that is that the scuba signal for low on air is a fist/hand on the chest.scuba signals low air  So if you are touching your chest to me that is the scuba signal for you are low on air and I will be taking you to the surface at that point.

The best and easiest scuba signals for telling your dive master and dive buddy how your air management is going is the simple ok sign.  This tells your buddy that you have been watching your air and you are ok and have plenty of air remaining. The other preferred way, especially for a new diver is to signal with your fingers on your arm for your remaining air in thousands and with your fingers for hundreds. So for say 2400 psi in your tank the scuba signals would look like this; 2 fingers tapping your arm and then hold up 4 fingers. A simple and non-confusing scuba signal for letting your dive buddy and the dive master know how much air you have and that you have been watching your air supply.
