I was gifted a previous generation inreach last year for my birthday. My wife wanted me to have one for her peace of mind during my BWCA trips. It works great, especially if you have a smartphone. It has the ability to connect via Bluetooth which makes typing messages easier. If you do not have a smartphone, you can program a number of preloaded messages, or use the not so efficient user interface to type messages through the device. They also allow you to activate for a month at a time if you wish.
I have the delorme se model and not the updated garmin model and have been very happy with it so far. There are probably still some delorme models floating around out there. Mine was purchased from Amazon.
it also has the ability to get weather and track your progress with tracking points as well as function as a full on gps through a smartphone.
hope this helps you in your quest
