Selling my ACR ResQLink+ Personal Locator Beacon. Battery is good until September 2023 (see picture) but can be replaced. Batteries last 5 years.
This is a great tool for backcountry safety. No monthly subscription fees or other costs. Simply flip up the antennae and press the button to contact a satellite which will in turn alert SAR, other authorities, and emergency contacts you set up.
Still works perfectly and will complete the test function. Selling as I purchased another device and no longer need this one.
Originally paid about $300 for it at REI if my memory is accurate.
