Atomic ST-1

By Jerry B.

 -  Moses Lake, WA, US

The weather & surf was bad due to the Yutu cyclone. In 3 weeks the dive boats on Maui often cancelled due to conditions & bad viz. Only got 2 boat dives in. That said, my wife & I both have new Atomic ST! regulators & they are not only convenient (plenty of ports for your regulator, inflator & octopus) but very comfortable with the built in swivel at the 2nd stage.

 

Awesome Range Of Movement!

By MANNY E.

 -  Austin, TX, US

This regulator with the pivot head ball is awesome! Breathing is smooth; no tight, restricted flow at depth. the ball articulation allows for a more comfortable fit; less pressure from the air hose pulling on the mouthpiece. Materials are top notch. * Beware the swivel head articulation! It can pivot upwards and free-flow, when you're on the surface, if you don't have a retractable vest cord-caddy attached to it.

The Atomic Aquatics ST1 Swivel Sealed Regulator has a stainless steel first-stage. Stainless steel delivers virtually the same corrosion resistance as titanium at a lower price. Stainless steel does not require protective chrome or nickel plating processes that can be harmful to the environment and is 100% recyclable. The first-stage is machined from solid 316-grade stainless steel.

The ST1 is a balanced flow-thru piston design using Atomics jet seat high flow stainless steel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic employs a conical seat and blunt end piston. Atomics' valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure. The ST1 is also freeze protected with a factory sealed first stage that also prevents contamination such as silt and sand from entering the valve mechanism. The regulator is Nitrox ready for mixtures Up to 40% out-of-the-box. The first-Stage has 2 high-pressure (HP) 7/16" and 5 low-pressure (LP) 3/8" ports. The LP ports are on a swivel turret for ease of hose routing.

The ST1 second stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. The ST1 Series second stage is built-to-last with a titanium demand valve body, lever and sealing orifice. The diaphragm is made from high quality silicone rubber. This pneumatically-balanced poppet second-stage has Atomics patented seat saving dynamic orifice which unlike most second-stage orifices is a floating valve design which reduces wear on the second-stage poppet seat when the regulator is not pressurized adding life to this important seal.

The ST12 series second-stage regulator is equipped with Atomics patented automatic flow control (AFC). This unique diaphragm activated vain automatically controls the flow and venturi-effect of the second-stage for optimum breathing resistance at all depths. The second-stage does have a soft over molded rapid adjustment knob for rare special situations. If you have ever experience the pulling effect" of the regulator second-stage when you turn your head underwater, those days are gone with Atomics comfort swivel. Perhaps one of the most admired features of Atomic second stages is the patented comfort swivel which allows 30° rotational movement without binding or kinking. The regulator comes equipped with a 3/8" threaded 32" (81.3 cm) low-pressure hose. The regulator weighs 2.3 lbs. (1059 g) and comes with an owner's manual.

This product can only be shipped to U.S. addresses.

Works like a charm

By enbassist

from Columbia, SC, US

Effortless, easy, comfortable, reliable, quality. Very glad that I bought this. I had to swap the mouthpiece out b/c while it's goo quality, it's a front-of-the-mouth (short) mouthpiece and I didn't feel like I was getting enough air. Would recommend this to anyone.

Questions about this item:

Shopper  Why Did You Choose This?
MELVIN M  Quality of presently owned Atomic products.
Shopper  is this ideal for tech diving?
Monica s  Depending what you are considering Tech diving, this is an environmentally sealed first stage, so good for cold water diving and eliminating contaminates in the first stage. The regulator comes factory ready a 40% nitrox.... So I would say yes, but depending on what you consider technical. Obviously if you are doing higher content mixed gases then you need to take it to a technician to have it ready for that.
