Spiegel Relaskop® is used in variable plot and Three P sampling. American Scale reads in English units (sq. ft.acre, inches, feet). It is used where trees are smaller than 96" dbh on level or steep terrain. Metric Scale reads in metric units (sq. mhectare, centimeters, meters). Excellent for a variety of forest conditions and tree sizes. Wide Scale is designed for metric measurements (diameter measurements convert to inches or centimeters). Recommended for trees larger than 244 cm (96") dbh. Works on level or sloping terrain. CP Scale is ideal when metric or English measurements are desired (basal area in sq. mhectare only). An optional Accessory Light illuminates scale in the dark. Leather case and illustrated booklet included.

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.
