The Aculon 6x20 Laser Rangefinder from Nikon is a distance-finding accessory designed to measure the distance of targets up to 550 yards away. The Aculon rangefinder features a Distant Target Priority mode that automatically displays the distance to the furthest target sighted when overlapping subjects are viewed.

The monocular can also perform single or 20 second continuous measurements, if required. The 6x magnification is suitable for identifying targets at mid-range distances and a long eye relief helps eyeglass wearers use the Aculon. Information is displayed in an in-view LCD display and an auto-off function saves battery life. Multi-coated optics, rainproof construction, a wide temperature tolerance, and one-touch laser activation make this rangefinder a full-featured optical instrument for many activities where determining accurate distances are critical.
