About

Jake for stratigraphy

Read full description

Jake makes measuring a stratigraphic section a snap. Place the device on a bed, and with a tap of a button, record your dip and dip direction. Arrows tell you when your device is pointed in the direction of dip and inclined at the correct dip angle. No more futzing with hard-to-read clinometers and compasses!
