Continuous high speed non- magnetic survey
DeviGyro is a driller operated survey instrument supporting high speed continuous surveying, overshot mode and even core orientation.
It is a miniature non-magnetic, memory, reference survey tool based on MEMS gyroscope technology. The gyroscope technology detects and quantifies any deviation the instrument is subjected to as it traverses down the borehole.
A DeviGyro survey may be performed continuously on the wireline or as a standard survey with quick stops according to a set depth interval. The running gear can be connected directly to the wire or to a standard overshot, and may be lowered or pumped into the borehole at high speed while surveying. Survey data can be recorded both during the in and out for comparison and additional quality control.

Continuous High Speed Non-Magnetic Survey
DeviGyro is a driller operated survey instrument supporting high speed continuous surveying, overshot mode and even core orientation.
It is a miniature non-magnetic, memory, reference survey tool based on MEMS gyroscope technology. The gyroscope technology detects and quantifies any deviation the instrument is subjected to as it traverses down the borehole.
No matter the survey mode the data always passes through an automatic and instant go/no-go quality check ensuring the results are always of the highest quality.
Depth Measurement
DeviCounter
DeviCounter digital wire counter is used to control depth during wireline DeviGyro surveys.
DeviCounter connects wirelessly to the operating handheld device and stays connected through the survey run, continuously updating the display with high accuracy depth data.
Small and simple size
DeviGyro’s small size is the perfect choice for all survey applications where efficiency and accuracy are required, independent of hole direction, inclination and location
Easy-fitted tool
DeviGyro can be fitted in a variety of running gear assemblies suitable for core drilling, RC, geotechnical drilling and open holes
Long duration? We’re on to it
With its low drift sensors and long life battery package, DeviGyro may be used over long durations, in inclined, horizontal or up-holes without affecting accuracy.
Why DeviGyro is a revolutionary, perfect choice
Find out how its revolutionary small size and proprietary algorithms, DeviGyro is the perfect choice for all surveys
High speed and quality
Surveys can be completed in continuous mode at speed up to 100m/ min(successfully tested up to 185 m/ min) or in standard mode with short stops at set intervals.
Intuitive and user friendly Software
DeviGyro is operated by an intuitive and easy to navigate Android application that connects to both DeviGyro and DeviCounter, combining the data automatically and accurately
Very little maintenance
With its miniature size and robust sensors, DeviGyro requires very little maintenance and repair
Running Gear Options for DeviGyro
Adjusting to your operations, we provide a wide range of running gear for your best need
DeviGyro RG40 Standard
Ultra-versatile survey solution for most types of in-rod applications
Optimal for a wide range of drilling applications.
DeviGyro RG40 Standard Survey Mode running gear makes the DeviGyro 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 Standard 40mm RG40 running gear includes our custom designed and built asymmetrical centralizers for surveying within a range of BQ to PQ sizes, with no loss of accuracy.

Frequently asked questions
Although DeviGyro has been successfully tested at speed of 180m/ min, the maximum recommended operating speed is 100m/min
Assuming a moderate 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.
Yes, it can. In that case you have to take stationary readings at specified depths. Whenever possible, however, continuous surveys are recommended. They give better accuracy because they have the benefit of precise depth information from the DeviCounter.
No, 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.
