Tools Used in Inventory
- Biltmore stick - utilizes ocular trigonometry to quickly measure diameter and height
- Diameter tape - cloth or metal tape that is wrapped around the bole, scaled to diameter
- Caliper - two prongs connected to a measuring tape are placed around the most average part of the bole to determine diameter
- Relascope - multiple-use tool that is able to find tree height, basal area, and tree diameter anywhere along the bole
- Clinometer - common tool used to measure changes in elevation and tree height
- Cruising rod - similar to a caliper, calculates the number of pieces of lumber yielded by a given piece of timber by measuring its diameter
- LASER Scanner used with computer software to calculate the metrics from the collected data.
- Wedge prism - a small glass wedge that refracts light to create visible offsets in order to be able to choose which trees at a sampling point should be included in the sample.
- Data collector - an electronic device used to quickly enter sample data, geo-locate the data, and, in more modern times, to also access reference, web and historic materials while timber cruising.
- Increment borer - a device used to retrieve a cylindrical sample of wood material orthogonally from the stem while doing as little damage as possible to the remaining tissues.

Famous quotes containing the word tools:
“At the utmost, the active-minded young man should ask of his teacher only mastery of his tools. The young man himself, the subject of education, is a certain form of energy; the object to be gained is economy of his force; the training is partly the clearing away of obstacles, partly the direct application of effort. Once acquired, the tools and models may be thrown away.”
—Henry Brooks Adams (1838–1918)
