I've enjoyed and used the SPOT, SPOT2 and SPOT communicator. They have always tracked well and my check in messages always went through. I'm a happy spot customer who rides solo in very isolated areas, I do trust my SPOT completely to function as they have for years and lots of use.
With that said, having two way communication seems like it could be very useful when things go bad and the only reason I'm considering switching.
When sending messages or tracking, does the Inreach need to be orientated a certain way like a SPOT?
