All-metal, German-made geological compass, based on the design by Dr. Clar, University of Vienna, for measuring azimuths and dip angles. Hinged cover has a graduated vertical operation. Dip angle graduation is 5 degrees over a range of 225 degrees, with reliable estimation to 1 degree. Mirror mounted on the inside of the cover in combination with notch and bead sights on the face of the compass enable accurate sightings to distant objects. Compass graduations are 2 degrees with reliable estimation to 0.5 degrees. Compass needle is unlocked with a push button. Compass dimensions (closed) are 93 x 76 x 22 mm and weight is 320 g.

SmartTool Digital Clinometer

The SmartTool digital level is a durable field tool that can be used as a level, plumb and clinometer. It digitally displays angles in degrees, percent slope and pitch (inches of rise or fall per linear foot) to an accuracy of 1/10 degree.

This unit is designed to sit on a surface and measure the slope of that surface.  It is not designed to sight on a distant object and measure the slope to that object.

Controls include:

  • ON/OFF - automatic shut-off if left idle for 6 minutes

  • HOLD - freeze or unfreeze display readings

  • LISTEN & LEVEL AUDIO - beeper will sound at level and plumb

  • CALIBRATE - simple two-step calibration procedure (recommended once per day)

  • Deg.,%,IN/FT - select display units

  • UP/DOWN ARROWS - show direction of tilt to reach level or plumb

  • LOW BATTERY - low 9V battery indicator

Dimensions are 6" x 1 1/2" x 2". Weight 7 1/2 oz. Housed in environmentally sealed polycarbonate housing. 9 volt battery provides up to 120 hours of continuous use.
