The Impulse 3 is more streamlined and higher performing than its predecessors. The Impulse snorkels feature a patented design, with a patented upper valve, a two-drain system and Aqua Lung's patented Comfo-Bite mouthpiece.

• The Impulse 3 uses a two-valve system. If a wave breaks over the snorkel, the patented, upper, annular valve directs most of the water out before it even reaches the mouthpiece.
• Patented Comfo-bite mouthpieces, which does not require the user to clench their teeth.
