From a review by 1.800.Gear ... I can attest that this feature really works. Tru-Target Technology is Nikon’s term for first or last target priority. This feature is useful to both rifle and bow hunters for measuring overlapping subjects – like elk in timber – or when brush partially hides the target. I find that first priority mode works great for small, unobscured targets like prairie dogs. Last priority mode is particularly useful when reflective objects like rocks or tree trunks are closer than a less reflective target like a game animal. Same holds true for squirrels hiding in tree branches. Target shooters will find this feature useful when confronted with multiple targets, particularly at distance.
