I have Garmin inReach. If I didn’t do so much remote camping, I’d probably just go for the iPhone and skip the inReach cost. I’ve been in situations where I had inReach service for 5-10 minutes per hour because I was in a canyon. A storm was coming in and I was texting my sister for weather updates (this was before inReach had a weather function) and it was not ideal. In the end, the weather was a lot more severe than the reports my sister reported but obviously I’m ok. It was scary to hear a roaring sound ramp up in the pitch black of the night but exciting when we woke up in the morning and realized that we camped in just the right spot. I was talked into making a trip presentation for my kayak trip to a paddling group. A youtube version of the slideshow is here:
You can see all the waterfalls around us a little after the 8:20 mark
All that said, because I‘m an Apple fanboy, I’ll eventually have both when I upgrade my phone.
