I don't know about this model, but the one I have has a problem. The buttons, were they are, and how easy it is to push them, get pushed easily in a pack or on your person. Consequently you'll find the thing dead.Knowing this helps a great deal. Used it all season with out a problem except that it's settings would change. The button must have been pushed. Does a good job. This one doesn't go under 25yrds., but who cares about that. JFYI, the yardage reading is not the same from a tree. I check from the ground and then in a tree to know the difference. The difference is as much as 5 yrds.
