Dolphin Rebreather action.

[Freedive WI]

Fred,
being a freediver, and certified on the Dolphin, I would say no.

The Dolphin still has some bubbles expelled from it and I remember hearing noises that the valves made. If nothing else, you can still hear your own breath as it moves through the loop. Having said that, a rebreather is still WAAAYYY quieter than OC.

While a Rebreather might cut down on the amount of gas used, my dive buddy just got back form Cozumel where he used zero tanks in a weeks worth of diving and hung with the scuba crowd the whole time. He was also allowed to zoom back and forth between different depth levels, which wouldn't work out too well on a rebreather. I bet it was nice not to be as dehydrated at the end of a dive, as compared to being on OC.

Now, back to rebreathers. ;D
