The Alpen 10x42 laser rangefinder binocular helps hunters do just that by combining two classical optical aids into one versatile unit. This waterproof binocular has a 42mm objective diameter that brings in lots of light without adding burdensome weight and features fully multi-coated, extra-low dispersion (ED) glass to maximize light transmission, which makes it easier to scout targets in twilight or other low-light situations.Once a target is spotted, the rangefinder feature can calculate the distance to the target accurately with lightning-fast speed. The unit's rangefinder component, which has a hard target range of 5000 yards and a soft target range of 1700 yards, has both a line of sight setting and an angular distance setting for environments that require angle compensation. It also is outfitted with a scan mode for live distance measurements.Item Number 673LRMagnification 10xObjective Lens Diameter 42mmLens Coatings UBX + FMCClose Focus 6m / 19.6ftFocuser Type CenterField of View 6.1 degreeEye Relief 0.56in / 14.3mmExit Pupil 0.165in / 4.2mmDiopter Focus -5.0 - +5.0Waterproof Yes, IPX7Range Reflective Target 5000yd / 4572mRange Building Target 1500yd / 1371mAccuracy ±1 @ < 300yd ±2 @300-1500ydInclinometer ±60 degreeInclinometer Accuracy ±1 degree @ >-30 degree - <+30 degreeUSA Limited Lifetime Warranty when product is registered within 60 days of purchase
