Oceanic Regulator

•Remember, increasing inhalation resistance can prevent undesirable breath- ing gas loss. It will not conserve breathing gas while you are breathing from the Delta.

Storage Setting -

•At the conclusion of a diving day, or when storing the Delta for any length of time, rotate the adjustment knob 'counter clockwise' until it stops. This re- lieves excess spring pressure from the poppet seat increasing its service life.

•Immediately prior to the next dive, reset the adjustment to the normal pre dive setting by turning the adjustment knob 'clockwise' 1/2 to 1 turn.

Omega II and Omega II with Swivel

The Omega II is a high performance servo-valve assisted second stage regulator with a side-exhaust. Inhalation ports surround the main valve, providing greater surface area, less resistance to breathing gas flow, and higher flow rates creating more natural, easier breathing than other types of second stages, regardless of depth.

Due to the Omega II's servo design, a hiss may be heard upon being pressur- ized. This is normal for the Omega II.

Due to its configuration, there is no natural reservoir to catch and hold any water that may enter the Omega II, therefore you may experience a mist of water that will be constantly expelled. There is no difference in breathing or relative wetness whether you are upside-down or right-side-up. This makes it ideal as an octopus.

The unique side-exhaust directs bubbles away from your field of view. Excess water is expelled by tilting your head to the left (lowering the exhaust valve) when exhaling.

Upon entering the water, free-flow can occur if the exhaust valve section is placed in the water before water has a chance to enter the mouthpiece. The best way to enter the water with the Omega II is with it in your mouth.

If this is not convenient, point the exhaust valve end up and immerse the mouthpiece first to ensure that water fills the body before pressure is exerted on the diaphragm that may cause it to free-flow.

When planning to resurface, removing the Omega II from your mouth while still underwater floods the second stage with water, preventing free-flow.

Most Omega IIs are shipped from the factory with a 180 degree Swivel that reduces jaw fatigue and provide for the convenience of underarm operation and ambidextrous operation.
