The Manta Industries Regulator Necklace is made from soft yet durable silicon rubber and is perfectly designed to fit around a diver’s neck, with or without a hood, to keeping auxiliary air source close. Keep your alternate air source where you need it! Intelligent one-piece molded design means no fracture, stress, or failure points. Durable, no-memory silicone rubber is one size that fits all. This is a heavier-duty version than you will commonly see. It is also the standard nine-inch diameter.

This design comes from a technical-diving aspect. For the out-of-air diver, you donate the regulator from your mouth. You then swiftly insert the regulator that is hanging on your neck into your own mouth. The process is two seconds rather than ten seconds or more of fumbling and trying to find your octopus which is buried who knows where -- lodged in a pocket or tangled in a mess with other hoses or caught in your SMB. Meanwhile, the out-of-air diver has already ripped the regulator from your mouth and, in an unnatural state of panic, will not give it back. And who knows -- the life you save may even be your own!
