Suunto Tandem Global Compass/Clinometer with Declination Adjustment With Declination Adjustment

Combines a liquid damped precision compass and clinometer in one compact, rugged aluminum housing that protects against impact, corrosion, and water. Clinometer scale is graduated in percent and degree (0-90°, 0-150%); compass scale is in azimuth (0-360°) with the option of declination adjustment (20° East and West). The compass is balanced for global use and is graduated in 1/2° increments, and the clinometer is graduated in 1°/1% increments. Both compass and clinometer are individually calibrated. Engraved inch scale and cotangent and cosine tables to 45 on the back. Threaded tripod socket. Includes case and lanyard.


TruPulse® 200 Rangefinder/Hypsometer with Bluetooth

Compact and lightweight, TruPulse rangefinders/hypsometers allow you to view through the lens so that you can pinpoint the laser directly along your line of sight. And because measurements are displayed through the viewfinder, you never have to take your eyes off the target. The TruPulse can measure distances up to 3,280’ (1,000m) without a reflective target. Results are displayed in feet, yards, or meters. An integrated tilt sensor allows you to measure horizontal or vertical distance and calculate an object’s height instantly by using the built-in three-shot routine.  The TruPulse diopter is adjustable for comfortable viewing – even for eyeglass wearers. The housing is IP 54 rated for water- and dust-resistance, and features an RS 232 serial port to download data. Includes carrying case, lens cloth, neck strap, and operating manual.


Suunto® MC2 Navigator Mirror Sighting Compass with Built-In Clinometer

Liquid-damped magnetic steel needle and long-lasting precision pivot. Built-in magnetic declination screw and magnifying lens. Sighting mirror with luminous points. Additional sighting hole. Clear protractor base is imprinted in red and features skid-proof rubber map feet. Clinometer measures heights and slopes to °90°. Lanyard and declination tool included. Baseplate Dimensions: 2-1/2” x 3-13/16”. Features a magnifier in the base, 1/20 inch scale, a mm scale, plus 1:25,000 and 1:50,000 map scales (except for 37184 which has 1/20 inch scale, a cm scale, plus 1:24,000 and 1:50,000 map scales).

Learn about the real lives of benthic macroinvertebrates in the wild! Uncover the secret lives of macros such as mayflies, damselflies, midges, caddisflies, and stoneflies. Witness the underwater transformation of these organisms into winged adults.


Learn about physical, biological, and chemical factors of water quality and the analytical procedures for their measurement. Understand the basics of waterway surveys, program planning, data analysis, and reporting.


Understand a broad range of subjects and issues: Forest Ecology, Geology and Soils. Forest Meteorology and Climatology. Forest Insect and Disease Management. Fire Management. Timber Measurements. Timber Inventory. Silviculture. Genetic Improvement of Forest Trees. Logging. and more.


Learn how to think on your feet in the field, improve the accuracy of your rock core logs; reliably measure core recoveries: Total, Solid and Modified; measure Rock Quality Designation (RQD) with QA/QC steps; prepare consistent descriptions; analyze rock as the drilling program progresses; quickly characterize fractures and their distribution; build the geologic framework from boring to boring; identify general rock types; obtain guidance for placing and labeling cores in the box; and reduce log editing time.

Soil Composition

Soil composition is an important aspect of nutrient management. While soil, minerals and organic matter hold and store nutrients; soil water is what readily provides nutrients for plant uptake. Delve into the benefits of composting! Explore biomes, the food web, and the vital role of worms in composting.
