Scuba Diving Signs Related to The Air
12. Scuba Sign to Say “How much air do you have?”
The dive advances, but the time we have to enjoy is limited by the air in our cylinder. For this reason, the next signal is performed several times throughout a dive. We are talking about how to ask how much air your dive buddy has left?
There are two ways to do this. The most common is to point the gauge with the middle finger and the index finger. The second way is to point in exactly the same manner but to the outstretched palm of your hand, instead of the gauge.
13 & 14. Scuba Diving Hand Signals “I am Low on Air” and “I’m Out of Gas”

If he moves his hand horizontally in front of his throat as if he were to cut off his own head. He is out of air.

16. The Scuba Diving Hand Signal For “Cancel”

17. What Does a Thumbs Up Sign Mean in Scuba Diving?
Although the dive time is never enough for us, we need to finish it properly and use the “ascend” scuba diving signal in the correct way. To indicate this, we must place the thumb-up. Take care not to confuse this signal with the one that indicates OK, during the dive. Underwater, a thumbs-up indicates something very different from what we are used to on land, and mistakenly using it to say you are OK could end the dive prematurely. You would not want to ruin a dive because of a simple oversight, would you?
