We’ve all seen it in the movies. The main character splashes into the water, a cool looking mouthpiece gripped in their teeth, and they proceed to escape, do battle, or otherwise enjoy the benefits of a scuba system without the requisite scuba gear.

There is a whole minimalist sub-culture in recreational diving, dedicated to minimalizing the amount of gear they need to safely dive. So what’s brought all this on? The Triton Artificial Gill.
