Tripod improves accuracy over handheld use.
Brunton Sherpa handheld meteorological instrument. Measures wind speed, temperature, air pressure, altitude, time,....
Similar to the Suunto Tandem, the Brunton Master Duo combines a clinometer and a compass.
Petzl caving helmets. Some are available with a helmet lamp.
7.5 in chisel for collecting samples.
Diameter at Breast Height (DBH) tape. Tape 2 is 10m, the rest are 8m.
Wind meter for collecting wind speeds from 2-66 mph.
This auger comes with a dead-blow mallet and a bent spatula. It can be used for hard soils.
Folding trowel for soil sampling. Can attatch to belt.
For Loss-On-Ignition studies of organic matter content of soil samples. In this lab, use a relatively low-temperature (360 to 375°C) protocol.
Garmin handheld GPS. 3-5 m accuracy.
Backpack with standard 5/8" mount for external antenna like the Trimble Zephyr with antenna cable.
GPS Range Pole with Bipod, for Benchmarking.
Various hand lens' available. Most 10x magnification
Hand level for use in surveying. 1x, 2x and 5x models.
Motorola handheld radios.
Hanna thermocouple with probe can measure temperatures from -50 to 250 C. The probe is 10mm in width and 500mm in length and can tackle the toughest soil. Thermocouple comes in a hard case.
Increment borers for sampling softwood trees. Requires training. Sample Holder available.
Wooden tripod, so a bit more stable (though heavier) than aluminum.
Wooden tripod (a bit more stable but heavier than aluminum tripod). Used with total station, digital level, laser level.
"Direct-Reading" style, meaning it reads from the top downward. Metric.
Laser Technologies Impulse 200 Laser Rangefinder, with compass module. Best used on a range pole for steady readings.
MDL LaserAce Rangefinder with compass module.
Trick on communicating with Terrasync, from Pete Christian:
Digital level in two models: 100M and 250M. Both have memory so ids, heights and distances can be downloaded. Used with "bar-code" stadia rod.
The Leica Builder 503 Total Station is a relatively easy-to-use instrument, but has exceptional accuracy: 3 seconds of angle horizontally and vertically.
Requires prism and prism rod:
Mirror stereoscope for measuring and mapping features on stereo pairs of aerial photography.
Extends to 7 m, to be used for an elevated platform for photography. Includes camera mount. Only appropriate for light-weight cameras at its full extent.
Using Collector for ArcGIS Online, receives data from a Bluetooth-connected GNSS Receiver such as the Trimble R1.
Easy to use laser rangefinder, accurate to 1 m. Reads distance & vertical angle, with built-in settings for horizontal and vertical distance, and tree height.
For drawing accurate maps in the field. Note: do not overtighten on tripod -- will become impossible to remove.
Used to test the strength of soils.
Extends to 4.65 m. Marked in meters for water depth reading. Used with
PVC frames, various sizes.
Measures in mm as well as in. It can either be mounted or put in soil.
refractometer for salinity measurement
Sharpshooter shovels are good for exposing a vertical soil profile.
Similar to the Brunton Sherpa, this device can measure windspeed, temperature, relative humidity and barometric pressure.
Used to measure relative humidity.
Used to measure noise pollution.
For measuring canopy cover percentage from the ground.
ID number is last three digits of serial number, engraved in the aluminum body.
ID number is last three digits of serial number engraved on the back of the instrument.
Similar to the Brunton Master Duo, the Suunto Tandem combines a clinometer and a compass.
For use with Swoffer Rod for measuring depth and positioning propellor at optimal depth for velocity average with depth.
For use with optical level. Metric and Imperial (decimal feet) versions. Round telescopic style.
Topcon 5-second total station.
Requires prism and prism rod:
Aluminum. Used with total station, digital level, laser level.
Tree calipers are more efficient than DBH tapes for measuring large numbers of smaller trees.
