Diving rebreather
SENTINEL
VR3
An integral CO2 monitoring system displaying CO2 levels in millibar on the Primary display and providing warning alarms at 5 and 10mb. The life of the sensor is several years (dependant on use) and it is simply periodically calibrated in ambient air. An integral filter system is user changeable and spare filters are supplied with the system. Existing Sentinel users can have their unit upgraded and dependant on the age of the Sentinel various price options exist.
VGM incorporates a user changeable algorithm with 'defaults' which mimic common algorithms in use today and allow the user to further customize the system. VGM is the first algorithm capable of a multi-model approach tracking deep-water, mid-range and shallow decompression issues.
The off-board gas connection kit comprises two high quality Swagelok female connector4s fitted to the gas blocks and two LP whips with male connectors for fitting to the off-board regulator first stages. The Sentinel off-board kit is the first to allow external gas to be routed both through the manual gas addition system and via the automation (solenoid/ADV).
Ballistic nylon breathing hoses covers are supplied to provide additional to the breathing hoses.
The Intelligent Secondary (Isec) Display removes the calibration potentiometers from the electronics head and allows the backup PO2 system to be calibrated from the Isec screen. This provides additional isolation for the backup PO2 system. In addition there is an option available to add a decompression algorithm (VGM) to the Isec so that it works as a backup dive computer.
The 5mm backplate is designed to evenly distribute weight when drysuit diving.
The software pack for the Expedition comes with additional software features such as VGM, alarm cancelling and an alternative dive display.
The PC data download comes standard with the Expedition.
