Yes, the POWERBREATHER is perfectly suited for all snorkeling enthusiasts. The innovative valve technology allows the swimmer or diver to experience snorkeling in a completely new dimension. When exhaling the air via the mouth during diving, you will always have free D-Tubes when reaching the surface. Irritating blowing out of water as with traditional snorkels is not necessary. Due to the fact that the Powerbreather has perfect ergonomics and supplies the snorkeling diver always with fresh air even longer snorkeling of great distances with flippers causes no problems.
