I am in the market for either GPS unit. I have been told by a guy I work with teh downloads and updates are cheaper from DeLorme than they are for Garmin and that more can be done with the Delorme. Personally I am not a techie person so 90% of what he tells me falls on ears that aren't comprehending anyway. However I do see that the Garmin is also compatible with a heart rate strap and I do alot of bicycling so I do see that being useful in tandem with the Garmin gps and my map my ride app on my phone that I keep track of my riding. Woudl the Delorme also do this? Here is what my future GPS to do: (I am knowledgeable enough to store waypoints, tracks, routes and such and pan the map to another spot and set it as my destination). 1). Stay on public lands in states that I hunt in to avoid trespassing fines 2). Get me back to my truck, camp, tent etc. I have played around with my coworkers Delorme PN-30 and it is cool that it has a satellite map on it. I am assuming the PN-60 will take a download of the BLM Map for Wyoming and overlay it right over that satellite map? I am seeing the purchase cost being close to equal on them.
