For optimal borehole surveying accuracy, it is imperative that the survey instrument is properly centralized in the drill hole. Especially in larger diameter, near-vertical drill holes predominantly seen in the civil construction industry, such as piling and raise boring drilling applications.
Complimenting the DeviGyro RG40 Standard’s adjustable centralizer system, the RG400 Centralizer Kit boasts heavy duty rollers and patent-pending rotating functionality, securing both smooth, high-speed descent and high precision. Adjustable between the range of 100 and 400mm / 4’’ to 15’’.
Compatible with the DeviGyro RG40 Standard borehole surveying solution, the RG400 Large Centralizer kit expands the already wide variety of surveying applications made possible with the DeviGyro technology.
