Get this guy a green vest, this is a solid run down of those two products. The only thing I would add, to make this product line even more confusing, There is currently a third choice (there were four for a time) The GPS Map66i is the Garmin version. A couple of years ago Garmin bought DeLorme and the inreach was rebranded as Garmin. It took a while for Garmin to come out with its own incorporation of the tech.
