Have you ever been diving and wanted to get someone’s attention? Using a rattler can be effective depending on how close you are but it can be a hassle. Maybe you’re following your dive partner and you want to say “hey the reef is to our right and we’re swimming against the current and burning air. Let’s head right and drift along the reef”. Or maybe you’ve spotted a massive moray eel or a shark and you want the other divers to come take a look. Doing this underwater is difficult because . . . well. . you can’t talk underwater . . . or can you?
Allow me to introduce the full face dive mask. Until recently these masks were used mainly for non-recreational diving like tech diving, commercial diving and research and film crews wishing to capture audio from the diver during filming. Now companies like Ocean Reef, ScubaPro and OTS offer high quality full face masks that at a more affordable price (relatively) to the recreational dive market.
