If you are a diver you know about about using hand signals to communicate since you can't talk under water... While taking two new friends diving I noticed that they have their own special dive signals... (they were using scuba and I was free a.k.a. breath-hold diving) and sorry... but you'll need to watch until the end of the video to sea the signals...
