Best of All Worlds!

By Manny O.

Delivery from Leisure pro was very quick;. The order was filled correctly. When an item was out stock/backordered, Leisure pro had it drop-shipped to me from the factory, and I was always in the communication loop.

 

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 ST1 utilizes Atomic's high-flow stainless steel piston and jet seat system. Its self-lubricating high-pressure piston seal ensures low friction and maintenance. Atomic's 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's patented seat-saving dynamic orifice extend the life of the second-stage poppet seat.

Equipped with Atomic's 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's 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.

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

Questions & Answers

Questions about this item:

BRUCE R  Does atomic honor the warranty when buying a used St1 on scuba.com?
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 before
Melvin M  Quality of presently owned Atomic products.
