The ProSensor System Explained 

Deckvest 5D 170 Pro Sensor Firing System is activated by contact with water. A compressed paper element dissolves to release a sprung needle which pierces the gas cylinder.

Sea, spray, or rainwater running downwards through the unit should not cause activation-only water flowing upwards will activate firing ... take a look at the short video of the 'fire-hose' test where a lucky test subject is fire-hosed with their deckvest on to demonstrate the protection against inadvertent inflation.


  • Very reliable activation when immersed
  • Easy to check and re-arm at sea
  • Easy to convert to ‘manual firing’ only
  • Pro Sensor has an indicator to show armed status
  • Water sensitive activation system 
  • Uses a compressed paper capsule that dissolves and releases a spring to puncture the gas cylinder. (Pro Sensor has indictators to show status of cap and cylinder) 
  • The cap is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down jacket will not cause activation. 


  • Can be prone to accidental inflation in heavy breaking sea conditions or if stored in a damp, unventilated location 
  • Cylinder can work loose over time so needs checking regularly 
  • Cylinder can corrode/leak if stored damp 
  • 3 year replacement date printed on firing cap   


Service interval commences from the first day of purchase - note that Spinlock deckvest owners are required to register product online to validate the extended warranty within 2 weeks of purchase.   We recommend an Owner Inspection every 3 months, and Service Centre Inspection is required every 2 years.   Note that if you are in engaged in yacht racing the race authority may require annual inspection.
