United Moulders Pro Sensor Elite Auto Double Point Indicator

This system activates when the cartridge comes into contact with water. The cartridge mechanism contains a compressed high powered spring which is held by a cellulose paper element. When the paper element comes into contact with water it dissolves and releases the spring which pushes a cutter forward to pierce the CO₂ cylinder and release the CO₂ gas. The gas then travels through the one way valve in the inflator head and inflates the lifejacket. Benefits of the Dual Point indicator system: the user has immediate visual check of the operational status of the cylinder and cartridge.

The Automatic system is backed up by a manual override, which allows the user to pull the toggle and activate the cutter to pierce the gas cylinder in order to inflate the lifejacket alternatively.
