How much does it take to get these things to go off prematurely?

I know I worried about it last summer. The fog was incredibly thick,
water was running off of every thing, rigging, arms, glasses.
Everything was just soaked.

Howard, my son and I have worn ours for two years in spray and rain and
they have not gone off. He was horsing around on a dock with his sister,
fell in, and cost me a rearming kit.

These suckers work.

I have done some dangerous boating, including trying to rescue folks who
didn't know what they were doing in nasty seas. On those occasions, I
used a regular PFD.

But for daily use, I always wear my auto inflating PFD.
