Nikon Hypsometer

Range 11 to 550 yds.; 10 to 500m; 33 to 999 ft.

Power One 3V CR2 battery (included).

The ultimate forestry tool, this precision rangefinderhypsometer provides accurate range, height, and angle measurements. The Forestry PRO features a three-point height measurement function that allows for accurate measurements even in dense areas of thick brush. Provided with a clear line of sight to a point on the stem, the unit calculates horizontal distance, then captures two other points to create an angle, and accurately calculates height. First Target Priority Mode allows you to range small objects and obtain an instant reading. Distant Target Priority Mode displays the range to the farthest target among the targets measured. The Forestry PRO features 6x magnification and provides several measurement readout options including actual distance, angle compensated distance (horizontal distance), angle (degrees), and height. Results are displayed in yards, meters, or feet. Featuring both an internal display and an external LCD display, reading the measurement data is easy. The Forestry PRO is waterproof and comes complete with a field case, quick start guide, and battery.

Increment Borers

Borer Bit Length depends on the size of the trees you will be boring. Length is measured from the tip of the threads to the end of the round section of the borer bit. This is the maximum depth the bit will penetrate. Core Diameter of the wood sample is determined by the inside diameter of the opening at the threaded end of the bit. 0.169" is commonly used for general forestry use, 0.200" for wood preserving testing and 0.500" for large amounts of wood for qualitative analysis. 2- or 3-Thread style is a matter of personal preference. A 2-thread borer has two threads on the cutting edge of the bit, each originating 180 apart. A 3-thread borer has three threads, each originating 120 apart. The higher thread pitch of the 3-thread borer will penetrate deeper per revolution than a 2-thread. A 3-thread will also produce less friction because more steel is in contact with the wood. The ease at which a borer penetrates wood depends on wood hardness, friction properties and capabilitystrength of the user.
