For durability and reliability as far as a gps goes, hands down I’d recommend the Garmin 60CSX if it were still available. The one I own has NEVER failed to get a signal where other gps’s I’ve used and others friends have used, have failed. Definitely a blue collar unit! Currently I use my phone with either GAIA or OnX. OnX most of the time. That being said, my truck and my camp and when I get lucky, my animal is marked on my Garmin. Cell phones batteries die, glitches in software happen. That Garmin is my piece of mind.
