Here you can find videos from my new mask attached Go Pro.
This one is a great example of a diving emergency. One of the divers on this dive left his buddy and the group without telling anyone to surface and fix an issue with his mask We had to pair up under water and let the dive master find the missing diver. You will notice at around 8:50 the wife of the missing diver getting nervous and frantic. I communicated with the other divers, paired them up, buddied up with her and kept her calm for the few minutes that it took for the dive master to retrieve the lost diver. Calm and cool prevailed but it is important to remember your training!
