Questions & Answers

BRUCE R : Does atomic honor the warranty when buying a used St1 on <a href="http://scuba.com" target="_blank">scuba.com?</a>darrick c : Hello Bruce, as long as you register it with the manufacture.
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.
Shopper : Why Did You Choose This?BARB L : Replacement of the same model as beforeMelvin M : Quality of presently owned Atomic products.

Great system.

Absolutely one of the best regulators I have owned. Easy breathing and super light but durable. Have logged 20 dives since purchase. Flawless

Atomic ST-1

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.

WORTH THE EXTRA CA$H

You can read about the engineering and innovation that went into Atomics products all day long. Once you get the ST1 in your hands and use it for the first time, you feel like your investment was worth every penny. Its nice to make a deep dive and not think about breathing or the comfort of your regulator. After you try the comfort swivel once, youll never go back! When you get below 100 feet, you might flood your mask by smiling after you realize how easily youre breathing. When you finally come out of the salt bath and rinse off your gear, youll appreciate the sold stainless steel first stage and all of the titanium in the ST1 second stage. When youre underwater, youre on life support. Having said that (if your like me) you want the BEST! If youre considering the T2X, you can save money with the ST1 and still have that same peace of mind. Either way, you cant go wrong!

Awesome Range Of Movement!

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.

Works like a charm

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.

Great regulator

By Kris

Great engineering and an awesome product.

The Atomic Aquatics ST1 Swivel Sealed Regulator boasts a stainless steel first-stage, offering corrosion resistance similar to titanium but at a lower cost. Environmentally friendly and 100% recyclable, 316-grade stainless steel doesn't need protective plating.

With a balanced flow-thru piston design, the Atomic Aquatics ST1 utilizes Atomic Aquatics' high-flow stainless steel piston and jet seat system. Its self-lubricating high-pressure piston seal ensures low friction and maintenance. Atomic Aquatics' valve seats, machined from a strong aerospace-grade material, guarantee reliability and 2 years or 300 dives without service. The ST1's diving performance excels even at low tank pressure and features a freeze-protected, factory-sealed first stage to prevent contamination. Nitrox-ready up to 40% and offering swivel turret LP ports, the first stage has 2 HP and 5 LP ports.

The ST1's second stage offers balanced linear flow for effortless breathing at all depths and conditions for scuba diving. Built with a titanium demand valve body, lever, and sealing orifice, it's made to last. The high-quality silicone rubber diaphragm and Atomic Aquatics' patented seat-saving dynamic orifice extend the life of the second-stage poppet seat.

Equipped with Atomic Aquatics' patented automatic flow control (AFC), the ST1 second stage optimizes breathing resistance at all depths. A soft, over-molded rapid adjustment knob is available for special situations. Atomic Aquatics' comfort swivel eliminates the "pulling effect" when turning underwater, allowing 30 Degree of rotational movement without kinks. The regulator includes a 3/8" threaded, 32" low-pressure hose and weighs 2.3 lbs. An owner's manual is also provided.
