Only The Best

As an instructor I only want the best for me and my students. That is where Atomic M1 reg comes in. I primarily use this reg for sidemount along with the B2 reg and use the M1 on a stage bottle for when I am teaching a deep class. I further recommend this reg if you intend to take any Tec courses.

Deep in love

I have of these and use them almost exclusively when diving on OC with twins. Recently I was forced to use a rented reg on the stage and this experience reminded me how much I love my M1s.

atomic quality at it's best

Bought it for a deco bottle. Just as awesome as every other atomic reg I have. I was thinking about going with a cheap reg, but figured I shouldn't skimp on something that if it breaks I'll get bent.

Outstanding regulator

I have been involved with teaching diving for four decades. I have used many regulators most costing much more than the M1. I have not found any that are as smooth and easy breathing as this regulator. I highly recommend the Atomic M1

Great in Demanding Conditions

I've used M1s for the last 5-6 years making 200 dives a year. I gave one to a friend and bought another one to replace it. It works quite well even in demanding conditions and diving around the world. I would not hesitate in recommending this regulator to anyone using air or nitrox

Atomic M1 Monel Regulator Review - $499.95 - Scuba Gear Customer Reviews

My experience was only thirteen dives and it is my first regulator. I selected it because its oxygen range can reach 80%. It will be easy for future other diving equipment condition request.

Very Nice!

I found this to be a very smooth, natural breathing regulator. Its adjustable second stage prevents free-flows on entry and allows for easy adaptation to your breathing preferences. The LP port on the top allows for the second to go up and over easily, though it makes for a messy set of hose above water. Very pleased with the performance.

I'm gonna buy a second one !

I used this M1 regulator in Dahab red Sea for the first time and I did about 30 dives with. It is my first personnal reguator and I found it great ! Very easy to breathe without any effort. More it is very comfortable in my month and I could adjust it with kit conversion DIN that I found at Atomic website. So I tried it with either Air or Nitrox up to 36% and it wasworking very well in the two case.

The Atomic Aquatics M1, designed for extreme diving situations, uses state-of-the-art metals like Monel, 316-stainless steel, zirconium-coated brass, and titanium. Monel is employed in the first stage for strength, corrosion-resistance, and oxygen compatibility, while other metals are used throughout the second stage. With an expanded performance range, the M1 caters to recreational or technical diving conditions, meeting virtually any requirement or scenario.

Built on the acclaimed T2 and B2 platforms, the M1 features a balanced flow-thru piston design with Atomic Aquatics' jet seat high-flow Monel piston. Its exclusive high-pressure piston seal system is self-lubricating, requiring low maintenance. The M1 offers superior diving performance even at low tank pressure and is Nitrox-ready up to 50% or oxygen mixes up to 80%. Additionally, it is freeze-protected and contamination-resistant with a factory-sealed first stage.

Designed for easy breathing scuba diving at all depths and conditions, the M1 second stage is ideal for cold water diving with a thermal heat sink and improved super-dry exhaust valve. It features Atomic Aquatics' patented seat-saving dynamic orifice, which prolongs the life of the second-stage poppet seal.

Equipped with Atomic Aquatics' patented automatic flow control (AFC), the M1 optimizes breathing ease at all depths. It also includes a rapid adjustment knob for unique situations. The high-flow second stage design significantly reduces breathing effort, while the wide exhaust deflector enhances visibility by dispersing bubbles. The regulator comes with a 3/8" threaded 32" (81.3cm) low-pressure hose and weighs 2.6 lbs. (1,191 g). An owner's manual is included.
