Product Description

Borehole Drilling Orientation Tool Vertex Angle Azimuth Survey Tool North Seeking Gyro Survey Tools Magnetical Non Magnetical Borehole Survey Tool

GDL series adopts a kind of high sensitive angular velocity sensor that can be sensitive to the rotational speed of the earth, no directional calibration is required before use, and the downhole self-search north without accumulated error. The measurement result is true north azimuth, which can be used in magnetic mining areas and drill pipe.

Easy to use when measuring by wire rope or drilling tool. It has many advantages such as high precision, small volume, light weight, small zero drift, long life and easy maintenance.
