I have just been given 3 good quality jackets, with one problem; they have both manual and auto inflation. However, it seems that the auto-inflation is a seperate module that screws onto the bottom of the mechanism inside the jacket; and, I can unscrew it! Does anyone see any problem with doing this, and then using the jackets as standard manual ones?
I am tempted to throw the bit I unscrewed into the bath, and see what happens...
