Atomic Aquatics M1 Regulator Yoke Sealed Open Box

Quick answer: This is a regulator from Atomic Aquatics. This is an open-box unit, so condition and included parts can differ from new. Check the listing details, and note that open-box stock is usually a single unit that sells quickly.

Why it's worth a look

A regulator doesn't come in sizes, but comfort still matters. Owning your own means you know its service history, you can fit a mouthpiece that suits your jaw, and you can route the hoses so nothing tugs when you turn your head.

Before you buy

Match DIN or yoke to the tank valves you use most, and confirm a local shop can service it. Have it set up and bench-checked by a qualified technician before your first dive. Read How to Pick Scuba Regulators That Fit Your Diving. More options: Regulators.
