I've been looking at these two devices, and I think I'm leaning toward the inReach because of the service plans. I really only need a satellite ELT maybe 1.5-2 weeks per year. The rest of the time I have cell coverage 99+% of the time and my phone works fine for everything. I can't see spending $200/year for service I need less than two weeks. But I could see spending $35 for a month of service only when I do need it. The Spot appears to have full year plans minimum, while the inReach has monthly plans. It looks like if I only activate the inReach one month per year I come out ahead. With inReach, is it really that easy/reliable to activate a dormant device? Can I go onto the Garmin website, pay the piper, and have reliable full service with a fully activated device that's been sitting in my drawer dormant for the past 11 months, and have it go dormant a month later (assuming I don't select auto-renewal)? And do this year after year? If so, it looks like the inReach is a no-brainer. Plus, with the really basic Spot (the Gen3), is that one a "transmit only" device? If you send an "I'm OK" or an SOS, do you get any feedback that the message has been received? I kind of like the two-way communications of the Spot X and inReach SE+.
