FIRST STAGE The first stage is a 300 bar/4350 PSI balanced construction. The diaphragm seals the first stage to protect it from foreign agents (such as sand) that could negatively affect its performance. It has two high-pressure ports (one each way) and four low-pressure ports. There are plenty of options that allow you to customize your equipment. SECOND STAGE Poseidon's Jetstream/Odin offers incredibly easy breathing at all depths and guarantees you enough air, regardless of your breathing rate. The regulator can be served from both the left and right, regardless of its position in the water. Jetstream/Odin is the first choice for technical divers and professional divers . This regulator is also used by the US Navy. All Poseidon regulators direct the exhalation bubbles to the sides, which gives You clear sight. The second stage can be used from the either side and independent of position in water.
