At the start of each sailing season I manually inflate all the PFDs on my boat
. This year, for the first time, one leaked and I have replaced it.
But now I'm wondering if there is a way to check the CO2 cartridges and/or should I simply be replacing them every so often? If replacement is recommended, how often should I do that?
Please note that on the cartridges it gives a "minimum weight". Do you think it sufficient to weigh each cartridge on an accurate scale and if greater then that it is okay?
