Thanks Renny, yes I'm in Prescott Az and fly alot at Moriarty each year. So to summarize for me to use the 10 min tracking with Delorme/ Garmin, it will cost 300+ a year. Granted I will get text msg I don't have with spot. With spot, I get the same 10 min tracking, and just pre set txt for 200/yr and no up front costs for equipment(I got my spot for free with sign up). Just trying to check actual costs.
