The DeviGyro RG40 Standard survey running gear is an excellent choice for most types of in-rod surveying. The adjustable centralizers cover a wide range of diameters and rod profiles while still supporting the high speed continuous survey operation the DeviGyro has become known for.

The familiar and rugged design of the RG40 Standard offers a user friendly and tough DeviGyro survey assembly. Still small and light in weight the RG40 Standard is always easy to handle and transport from site to site.

With the RG40 Standard also comes freely adjustable centralizers with the patent pending helix design. This design provides additional bias compensation and is one of the reasons why the DeviGyro can survey continuously at such high speeds.

Continuous surveys are performed by attaching the DeviGyro survey package to the wire and lowering it while monitoring depth and speed with the DeviCounter. In and out surveys are performed in the same run, providing additional quality control.

New large range centralizer for DeviGyro

For optimal surveying accuracy, it is important that the survey instrument is properly centralized in the drill string, especially in the large diameter near-vertical holes seen in the civil industry. Our new large range centralizers are adjustable between 100 and 400 mm or 4’’ to 15’’and compliments our current DeviGyro RG40 centralizers. It also boasts heavy duty rollers and patent-pending rotating functionality, securing both smooth high-speed descent and high precision.
