I just picked up an inreach when my spot subscription expired.

I got the 24.95 a month recreation plan, unlimited 10 minute tracking,
40 text messages a month.

I see this as a nice upgrade from the spot even with 10 minute tracking,
as the tracking on this is far more reliable.

I looked at the aviation plans, if you really need one minute tracking
be prepared to spend some big bucks on your subscription.

The two way messaging(texting)via satellite when you are out of
cell tower range is my main reason for switching.
