A good friend has given up boating and asked me to find a good home for his ACR ResQLink+ PLB. I know nothing about such items but see that it says the battery has an expiration of 05/2022. It has been registered with NOAA and you would have to update/amend that registration. I have the information.
New this sells for $289, will take $150 and I’ll pay for shipping. Let me know if that is of interest.
