The Forestry Pro is the enhanced model of the Forestry 550 Laser Rangefinder. This widely used and praised forestry industry specific laser rangefinder is now equipped with three-point measurement capability to meet market demands. This newly added function enables a user to obtain the height of a tree even when the top or base of a tree is blocked by branches or bushes, preventing the use of conventional separation measurement where the laser beam is required to reach those points. • Three-point measurement function: • The height of a tree is calculated using the horizontal distance and angles of both the top and base of the tree. • Easy operation enables measurement of actual distance, horizontal distance and height. • Target Priority Switch System offers two measurement modes: • Distant Target Priority mode displays the range to the farthest target among multiple results obtained with a single measurement. • First Target Priority mode displays the range to the nearest target among multiple results obtained with a single measurement. • The results are displayed on both internal and external LCD panels. The external panel displays all results simultaneously. • High-quality 6x monocular with multilayer coating for bright images. • High-eyepoint design affords eyeglass wearers easy viewing. • Capable of distancing different targets in succession, for up to 20 seconds, by keeping the button pressed. • Waterproof (up to 1 meter for 10 minutes), but not designed for underwater usage; battery chamber is water-resistant. • Measurement range: 10-500 m / 11-550 yd. / 33-999 ft.
