When in nitrox mode, for increased safety, to provide a means of monitoring the oxygen level within the breathing circuit, an optional Oxygen Partial Pressure (PO2 ) monitor may be fitted that can also be configured to supply decompression management data. Additionally an optional nitrox cylinder pressure alarm may be fitted which via a mask mounted peripheral display, provides a low cylinder pressure warning.

Excursion can be tailored to suit specific mission requirements via the use of the following accessories: 

•  Transport case

•  Full face dual mode mask

•  Bite mouthpiece and half mask

•  Buoyancy compensation jacket

•  Digicom through-water communications

•  Dry suit inflation system

•  Diver tool and test kit

•  Maintenance tool and test kit

•  300 bar 2 litre non-magnetic composite cylinders

•  300 bar 3 litre low magnetic composite cylinders

•  Spares package to suit customer requirements

For shallow water operations using a Tactical Diving Vehicle (TDV) where mission profiles are required to extend beyond the typical four hour single oxygen exposure limit, nitrox gas located on the diver and / or on the TDV, may be used for extending dive profile durations beyond four hours.

To support TDV operations, a bespoke dual flow nitrox gas switch valve may be used enabling the nitrox gas to be switched to low flow when on / in the TDV and high flow when undertaking free swimming.

The unique multi mission capability of Excursion and the Shadow family of Tactical Diving life support systems offers reduced through-life costs and logistical advantages that include:

• A common platform reduces costs associated with training divers to use multiple life support systems
• Common spares reduces the spares inventory
• Common documentation / manuals
• Reduced maintenance
• Fully user serviceable
