Both chips offer 1:24,000 resolution vs the 1:100k that a gps comes with and in that regard, they are the same. Both offer property lines with ownership which is critical for me as a tracker running a blood dog. My real question is a functionality comparison between the two.
For the record, the phone apps can’t work for me because when I am out of cell service AND tracking with a blood dog, I do have the ability to download maps because I don’t even know where I am going to track in advance. Additionally, I can geotag last blood with a touchscreen gps with a single tap without stopping the dog. Orientation back to that last blood is much easier with a Montana gps than a phone app.
Having said that, for normal hunting conditions, the phone apps work fine for most people. I use them a great deal.
