The Leupold GX-4i has a pin-locating feature, which Leupold calls “PinHunter”, that makes it easier to determine the distance to specific targets such as flagsticks by filtering out readings from larger more “reflective” objects (like trees) in the background. It’s a great feature to have, but we found that the Leupold GX-4i has slightly less room for error before the device starts picking up objects in the background, often providing background distances when the target tree trunk or pin is still within a portion of the target cursor. The advantage to this is that it is easier to purposely target background objects when you have little room around tree trunks or branches (true, we aren’t always in the center of the fairway…it happens), but overall we would prefer that “PinHunter” give a bit more precedence to targets in the foreground.

Leupold uses its pin-locating mode all of the time, including while the user is panning across multiple objects, instead of requiring the user to switch back and forth between a panning mode and a “pin-locating” mode. The GX-4i also includes a “Fog Mode” that can be turned on and off to improve performance in fog and rain to screen out false readings, essentially turning off the “PinHunter” mode.
