The SurveyMaster Compass/Clinometer with Incandescent Light from Brunton is a multi-function analog surveying instrument that includes both a bearing compass and an inclinometer. The aluminum housing features inch/millimeter scale and sine/tangent markings for convenient reference. A tripod mounting thread on both azimuth and inclination axes enables more precise and reliable measurements. A handheld design, liquid dampened inclinometer/bearing cards, and an integrated incandescent light make the SurveyMaster a full-featured measurement tool for your next survey or adventure. +/- 0.5° Azimuth/Bearing Accuracy +/- 90° Inclinometer 0-45° Sine and Tangent Scales Sapphire Jewel Bearing Inch and Millimeter Scales Aluminum Housing Integrated Incandescent Light Integrated Carrying Lanyard Azimuth and Inclination Tripod Mounts
