I own a PLB, and I don't bring it on every hike with the dog or walk in the woods. I will always have my iPhone though, I think this feature is amazing for the broad coverage and you have it on your iPhone 14 (and later) by default, attempt to call 911 and if you don't have service it's going to walk you through it. I've loaned my PLB to family members, and there was a lengthy instruction period about how to use it. This comes with none of that baggage, it's easy to use and you already have it in your pocket.
