I bet I InReach texted back and forth with our air charter service 25 times on a Caribou Hunt. We were going to get picked up after another party got dropped off. Ceiling was originally very low on our side of the mt range. When it lifted enough I texted him and he took off. Almost as easy as texting with my wife when we go separate directions on a shopping trip in town. They really likes the written info to fall back to.
Bet the Sat phone is handy too but heavy, expensive and a bit of a pain to read satellite schedules and wait for service prior to use....was not my phone, rather a friend was calling out a few yrs ago after a sheep hunt in BC. Looked like a pain, especially when the call dropped a few times.
And the price, around $570, really isn't that bad.I have the newer Garmin GPSMAP 66i inreach no need for a cell works great. Get one a few months before any trip there is a learning curve.
Both have worked and inreach efficacy has improved drastically in 10 years. For me it comes down to "what if" scenarios we all hate to think about. If any one of those nightmares of logistics or loss of life occur, Inreach doesn't give me emotional and intellectual satisfaction to properly and timely address the current sit report.
Most of my clients take an inreach, I use a sat phone.
