I am pretty happy with my Montana 600. My husband has an Oregon I think. It apparently has a problem with the compass which sometimes points in the opposite direction. This has led to a lot of cursing over time and once it came flying past me out in the woods 🙂
For spontaneous checks for something close by while on the road I love the iPhone App. I haven’t had a real chance to test the Apple Watch extension out in the field yet. My fist impression is that the overall design is quite good, but it seems to have issues with crashing and freezing.
