Operating the ACULON Rangefinder is so simple. Push the ranging button for instant distance reading. You can scan the visible target zone by holding the ranging button down. In this position the rangefinder gives a continuous range reading for up to 20 seconds. The clear display is great, uncluttered and leaves you free to focus on the object you’re ranging. After eight seconds of inactivity, the ACULON powers down to save battery.
Nikon ACULON Rangefinder is programmed to choose the furthest of what would be a split reading when there are more than one ranged objects in the rangefinders line of sight view. Because of this, the Distant Target Priority Mode is very useful if the object being measured is partially obscured by tree branches, bushes etc.
