Product Description

Gyro Deviation Survey Tool North Seeking Gyro Survey Tool Gyro Borehole Inclinometer Downhole Directional Survey Tool Gyro Borehole Survey Tools

The GDY-2GW is an easy to use and multi-shot tool. It is based on high quality Fiber Optic Gyro technology. The tool measures the self-rotation of the earth where the tool is placed at to indicate the True-North angle. The adapter with an ID number "420xxx" is used to connect a steel wire and slowly lower it down the hole. There is no switcher on the probe so you don't need to disassemble GDY-2GW during the whole measuring process. Once being assembled with the battery housing, the GDY-2GW will automatically start to work. The probe is powered by a 7.4V rechargeable lithium battery, which can be charged no less than 500 times. The endurance of the survey tool is about 20 hours.

 GDY-2GW Fiber Optic North Seeking Gyro is a Inclinometer which can measure azimuth correctly in the case section. It is operated by a portable controller and survey at each station by pre-set time interval.
Centralizers (Optional accessories)
The GDY-2GW has two optional sets of centralizers.The centralizers consists of a spring, four extension arms and four wheels. The spring is adjustable to fit to different inside diameters
