The Dip Needle has been recognized for the past 200 years as the one of the cheapest and simplest aids to the prospector and mining geologist.
The Dip Needle is a compass-like magnetic sensing instrument used by prospectors and geologists to measure the angle at which vein, fault or rock unit is inclined from the horizontal.
The instrument is held vertically and the needle then points towards a strong magnetic field in the earth; It is essentially a magnetometer.
This Dip Needle is a black round cylinder with a glass top which reveals numbers ranging from 0
to 360 around the circumference of the cylinder. An arm extends from the side of the cylinder
to the center and holds a magnetized needle. Needle swings on grid from 0 to 360 degrees.
Same unit can be found at Yukon Museum.
