We goofed! We promised a clinometer before pricing them. They are beyond the SD Envirothon’s budget. If you make contact with your local NRCS office, conservation district or extension agency, they may be able to get you access to a real clinometer to practice. The plan is to have one here for the skills review and at the competition.
To help your team members understand the math and science behind clinometers we instead are offering a Tangent Height Guide
This is essentially a low tech clinometer. These GLOBE protocols demonstrate how to use an even lower tech one under various circumstances.
