Deckvest VITO Hammar 170N Deckvest Re-arming Kit.
The Deckvest VITO uses the Hammar inflation system. This system is activated by water pressure and will not inflate until the cap is approximately 10cm under water.
The system is designed for use in more extreme conditions and extended offshore sailing. The unit has a single indicator to show is armed. Delayed inflation can be caused if fill immersion of the firing head is delayed by buoyant foul weather clothing.
