Nikon 6x21 CoolShot 40i Laser Rangefinder

Nikon designed the 6x21 Coolshot 40i Laser Rangefinder to be an invaluable tool that measures the distance to flagsticks up to 450 yards away, and reflective targets up to 650 yards away. Because distance doesn't tell the whole story, the CoolShot 40i takes the angle of elevation into account and provides an accurate range for uphill and downhill shots. The compact, lightweight rangefinder employs Nikon's proprietary HYPER READ algorithm to deliver fast and stable measurements regardless of the distance to the target, and First Target Priority mode that automatically displays the distance to the closest target sighted when overlapping subjects are viewed. The CoolShot has a measurement accuracy of ±0.75 yd/m, displays the distance in 0.5 yd/m increments, and is displayed within 0.5 seconds.

The 6x magnification is suitable for identifying targets at mid-range distances and a long eye relief helps eyeglass wearers use it comfortably. Information is displayed in an in-view LED display and an auto-off function saves battery life. Multi-coated optics, weatherproof construction, a wide temperature tolerance, and one-touch activation make this rangefinder dependable and easy to use.
