The Discovery D4000 Military Camo is a high-range, camouflage-finished laser rangefinder intended for hunting, long-range shooting, and tactical use. This device offers measurement in both meters and yards, an adjustable diopter (±3), and a moderately wide field of view (7.5°) for situational awareness. Its rugged body weighs about 302 g and its physical dimensions are approximately 10 × 7.2 × 3.7 cm. The camo finish helps the unit blend into natural environments, with multiple color variants (jungle camo, grey, white) offered by some sellers.
