Spot was a product that allowed live satellite tracking and limited check-in messages on the go. I've had my eye on these things for a while, but they always seemed overpriced and inconvenient. While the latest models have two-way messaging, these older ones can only send one of several pre-defined messages to your family and friends. They were supposed to be useful for checking in on long trips or tracking your progress in remote areas.
I recently picked up a few used ones for $75, then paid $80 for a single mont of service (a yearly plan is cheaper per-month, but there are a lot of extra fees and charges).
Since I don't have any really remote expeditions on my schedule, I took it on a cross-country train trip to see how it works!
