Diver adjustable inhalation effort:

Most downstream demand valve regulators are calibrated during manufacturing to a single, middle of the road operation.

Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment.

A simple twist of the GT 3s adjustment knob enables complete control...set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.

Patented Dynamic Adjustment:

A common objection to adjustable second stages is that divers cant imagine themselves twisting and turning a knob as they descend and ascend through the depths.

If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow.

Taking another stride beyond common second stage engineering, Oceanic designed a patented DYNAMIC ADJUSTMENT feature into the heart of the GT 3. This mechanically balanced valve maintains a preferred breathing resistance throughout the dive.

Set it once and the GT 3 automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no additional manual adjustment.

Computer optimized design:

Oceanic regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development.

The GT 3s unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation.


The GT 3s housing is made from an ABS/Polycarbonate composite blend of materials making the Delta 3 both extremely rugged and lightweight (5.8 ounces) and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives.

Patented orthodontic mouthpiece:

To further reduce jaw fatigue, the GT 3 features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.

Nitrox Compatibility:

The GT 3 is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts.

SP-5 Sport Piston First Stage:

The SP-5 offers all divers the opportunity to own a top-performing regulator at an unbeatable price.

Repeatedly rated as the best in its class, the Alpha SP-5 exceeds both Navy Class A and European CE standards. The Alpha SP-5 may have been the first regulator you ever used due to its widespread use in rental and resort operations.
