When choosing an inflatable life jacket, one option I always look for is whether or not I can convert it to manual activation to control when inflation occurs and to prevent accidental inflation in wet/extreme conditions.
From Coastal Cruising to offshore sailing, Spinlock Deckvest 5D Pro Sensor is the perfect candidate for these applications as it utilizes the uses the UML Pro Sensor inflator. This activation system is water/moisture sensitive that uses a compressed paper capsule which dissolves when wet, releasing a spring to activate the CO2 cylinder. This system is designed so that only water flowing upwards through the unit will cause it to activate. This prevents water, spray, and rain from accidentally firing the cylinder.
The conversion from automatic to manual inflation is very simple. The first thing you will need is your Deckvest 5D Pro Sensor, as well as the Manual conversion kit which converts UML inflation systems to manual inflation only. Once converted to manual, the only way to inflate your Deckvest will be by pulling the chord. So when you want to be in complete control of when your Deckvest ProSensor PFD inflates, the manual conversion kit is what you need.
