The Jetstream Mk3 is an updated version of the classic Jetstream
The Jetstream Mk3 is an updated version of the classic Jetstream regulator. We have now connected a Jetstream second stage with an Xstream first stage, thus creating a high performing regulator.
Colours: Blue, Red, Black, Brown, Grey, Yellow
Durable PVC housing with metal mechanism and rubber parts
Use either way up, Robust, durable, Approved for cold water diving, Reliable high performance
The number of feature has greatly improved safety and ease of use:
If debris has degraded the function of the exhalation check valve, it can easily be reached and corrected by just twisting off the diffuser. It is the only part which neeeds to be disassembled, and if it gets lost during the operation, the regulator will continue to function but must only be used for immediate ascent.
In case of a malfunction in the 1st stage causing excessive intermediate pressure, the safety valve integrated in the 1st stage will bleed off the excessive gas. This system both indicates to you that something is wrong so that you can take action, and because of the up stream servo valve technique, allows the regulator to continue to breath normally. Conventional downsteam regulators are likely to free-flow in such a situation.
Integrated surgical hose fixing points safely secures the regulatorto the diver, but in an emergency allows a distressed buddy to retrieve the regulator without undue stress to the diver. The dead air space is low at just 49.5 mi making CO2 figures minimal. Inhalation resistance is incredibly low and unaffected by depth and breathing pattern. Because of the unique Poseidon valve technology, there is no need for external adjustments. XStream is fitted with the new ergonomic mouthpiece Poseidon AIR, with asymmetrical lugs for the most comfortable bite.
All diaphragms are protected so that a strong current or using a scooter or tug does not affect either inhalation or exhalation. A minimal number of moving parts, coupled with thermodynamic engineeering, ensures the safe use in an extremely cold environment.
