Probably going to get a Hunter Safety System pro for hunting... Found a heck of a deal on craigslist for one. Claiming to be NIB, my only concern is product life... I'm sure several of you all have them as well, do they give a product life...ie replace after five years or something similar?

Thanks,
R

HSS says to replace after 5 years. If it really is NIB I wouldn't worry about shelf life, just replacing after 5 years of use, but thats just me.
