I would not call it the same. It has great functions and coupled with your phone works really well. I actually just used it and my phone on my last deer hunt. We were about 4 miles in and it worked to my standards.
Never used the garmin in reach but i did use the delorme.
Its nice. Though its far better in communication when you can connect bluetooth to phone. This is needed for gps to function more intuitively too. The screen is just so small. And if your carrying a phone too you may as well have onx maps and be far superior.
But it is usable. If combined with a good map and compass i think its okay way to go. Definitly not my choice way though.
