Use to extract cores of wood from trees or freshly treated poles, piling, lumber, or timbers to determine growth rate, age, tree soundness, and chemical penetration. Teflon® coating protects bit against rust and resin build-up and reduces friction. How to select the correct Increment Borer for your needs. Three factors to consider when ordering an increment borer are bit length, core diameter and thread style. 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 capability/strength of the user.
Spherical Crown Densiometer, Concave and Convex Model.
Helpful when establishing spacing standards in forest thinning and determining light requirements for regeneration. Both models feature a mirror reflector engraved with a cross-shaped grid of 24 quarter-inch squares to delineate a plot overhead. Slightly offset convex model when using so your head does not appear in grid. Walnut instrument case is 3” x 3”. Built-in leveling bubble. Operating instructions included.
A Spherical Crown Densiometer is used to determine thinning of a canopy, spacing for re-planting or when trying to gauge habitat suitability for a particular area.
Measure forest overstory density from unobstructed sighting positions. Also used as an indicator in wetland delineation work.
A Spherical Crown Densiometer works similar to a periscope. The spherical shaped mirror reflects the sky above you to help determine the amount of tree canopy.
A cross shaped grid with 24 quarter inch squares helps plot the overhead reflection.
In order for a Densiometer to be used properly, it must be level. Our Spherical Crown Densiometer features a built in leveling bubble, so the Densiometer can always be used correctly.
The readings from the Convex Densiometer represent a larger sample size than those from the Concave Densiometer.
Protimeter Mini Moisture Meter with Remote Probe
Provides you with instant moisture readings from 6% to 90% in many materials including wood, dry wall, concrete and masonry. 60 Bright LED lights range from green to yellow to red and are an indication of the likelihood of decay.

Spiegel Relaskop, Metric Scale
Used in variable plot and Three P sampling. American Scale reads in English units (sq. ft./acre, inches, feet). Use where trees are smaller than 96” dbh on level or steep terrain. Metric Scale reads in metric units (sq. m/hectare, 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. m/hectare only). Leather case and illustrated booklet included.
Eno Scientific Well Sounder 2010 PRO
A highly accurate instrument designed for measuring static water level in wells, piezometers, or boreholes. This portable handheld unit uses sound waves to measure the distance from the top of the well to the water level, eliminating the need to lower anything into the well. Unlike standard water level tapes, these acoustic meters are free from well contamination issues, and there is no clean up and nothing to get stuck in the well. Simply place the probe into a well cap opening and turn the unit on. Within seconds, the unit will display the static water level measurement. Will work on crooked, straight, or coiled pipes with up to a 90% blockage. Requires no external equipment for configuration settings and is capable of logging, storing, and downloading 25 million time/date stamped data points. Key features include immediate data capture, auto temperature compensation, calculation of drawdown and recovery rates, real-time clock/calendar to time stamp the log data, USB download, plus it is weather-resistant.
HawkEye DepthTrax 1H Handheld Digital Depth Sounder
The ultralight DepthTrax 1H delivers precise real-time depth readings from 2’ to 240’ with the slide of a magnetic switch. Slide the switch again to obtain current water or air temperature.
