Frequently asked questions
What is the maximum operating speed for the DeviGyro?
Although the DeviGyro has been successfully tested at speeds of 180m/min, the maximum recommended operating speed is 100 m/min.
How long does it take to survey a 100m drill hole with the DeviGyro?
Assuming a moderate average survey speed of approx. 60m/min, a 100m survey takes about 4 minutes. In addition, if you are conducting core drilling and running the OX assembly surveying becomes part of the drilling cycle and therefore survey time does not interrupt drilling productivity.
Is the DeviGyro north seeking?
No, the DeviGyro is not north seeking. It is a high precision, continuous rate gyro using north seeking principles and proprietary algorithms to determine the drill hole path from a known direction. Most continuous north seeking gyros operate in the same way. They determine a start direction and then measure the “rate“ of change from the initial reference.
