I also used the Garmin inReach. It’s nice being able to keep in contact with my wife in case something happens. If others hunting with you have it then you can link them up and see where they are at and communicate with them. That came in handy when we put an elk down and needed the help packing out it out.
I'm another one that's super happy with my InReach.
Thankfully I haven't had to use the emergency function yet, but the ability to call for help packing a moose 4 miles out over a mountain range was pretty invaluable. Also used it to call a water taxi to get my wife and I back to civilization after a gear malfunction while camping. We probably woundnt have died, but we'd have been miserable and probably sick from the cold and wet otherwise.
I tend to do most of my hunting solo, on foot, and pretty remote (easy to do here in Alaska) so my wife being able to make sure I'm still alive without bothering me (just hitting the "update location" button on the web map she logs on to) and knowing we can both contact each other if needed, gives her enough peace of mind to allow me to do more hunting
Nearly every place I hunt has no cell service. This is not a communication device. It does only one thing. Let's the SAR folks know who you are, where you are. Good anywhere in the world. No service fees.
And, it's not just for me. Anyone who is with me or who I might come across who is down will benefit.
You’ll need to define “best” based on the features that are important to you. They range from an emergency-only device with no subscription like the two already described above in this thread to devices that include a subscription and mix of additional services.
At the satellite text-level services, I like both the Garmin InReach Mini and the Zoleo. The Zoleo looks better if casual text communication back home is the priority (more messages for base cost). The Mini looks better if you want a mix of text messages and other features like tracking yourself and posting such things so others can see. There’s a thread in this forum discussing the Zoleo (which is newer). https://www.longrangehunting.com/threads/zoleo-experience.248472/
Above the satellite text-level service you’re looking at satellite phones. Depends what’s important to you.
