The Vertical Orientation Kit (VOK) simplifies and speeds up the vertical surveying processes with the DeviGyro. Instead of placing the instrument horizontally in the reference direction prior to the survey, the VOK allows setting the reference direction while the DeviGyro is already positioned in the drill hole collar.

The VOK comes with an easy-to-use clamping system that securely holds the DeviGyro in the drill hole collar during the referencing process. It is suitable for all available DeviGyro running gear configurations and allows the operator to rotate the survey assembly according to the reference direction. The included sighting device ensures that alignment with the reference direction can be achieved with high-level accuracy.
