Two valves keep water out
If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece. Any water that gets past it drains through the lower valve.
Impulse Classic
Two valves keep water out, and a gentle puff clears the reservoir
Impulse Classic belongs to Aqualung's Impulse snorkel line, which Aqualung introduced in 1989. Two valves keep water out. If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece, and any water that gets past drains through the lower valve. Clearing the reservoir below the mouthpiece takes a gentle puff. Want the mouthpiece to drop away when you are not using it? See Aqualung Impulse Classic Flex: the same two valves plus a flex section.

Impulse Classic or Impulse Classic Flex?

How do the two valves work?
If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece. Any water that gets past it drains through the lower valve.
