Automatic ( Hammar ) This system uses a firing mechanism that relies on water pressure to inflate the jacket. It will not inflate untill immersed in 10cms, or more, for 2 to 3 seconds. This has the obvious benefit to any user who will often be in contact with heavy rain or spray and wants to avoid inadvertent inflation. Infation will only happen when the user is in more than 10cms of water. When you want it! They also have a manual lanyard.
