Hi Diver! I'm Kelvin, click here to see accessories and upgrades for this product.
You cannot breathe directly out of a scuba tank because of the high pressure. A regulator reduces pressure to safe a level that can be inhaled by the diver. A diving regulator has two parts: the First Stage reduces the tank pressure and connects it to the Second Stage which contains the mouthpiece for breathing
Manufacturer Reference / Part No.:
A top-of-the line, fully adjustable regulator that joins the existing Legend LX. The Twilight Legend LX includes a smaller Comfo-Bite mouthpiece to reduce jaw fatigue designed specifically with women in mind. The Legend LX Twilight also features the revolutionary Master Breathing System (MBS) for simple breathing comfort control, and its own regulator bag for safe and stylish storage.
