My 5 yrs of battery life has long expired. I have a National Airborne Technology Sat Find 406 GPIRB. Anyone else have one of these units? Any suggestions on replacement and price?
Hey - I have an ACR 406 and although I don't have the manual here, I'm sure that I have to return it to the factory for a new battery. Check your mfr's website for further info, I guess.
