• Continuous surveying

• Multishot surveying

• Overshot mode

• DeviHead mode

• Core orientation

The DeviGyro is a brand new non-magnetic survey instrument providing high speed, continuous downhole surveying in a small and versatile package.

Designed with convenience and ease of use for drillers in mind, this cutting edge rate gyro system utilizes a complex navigational algorithm to deliver the high accuracy and standard of quality assurance required by our customers.

The extremely small size of the DeviGyro opens for utilization in wide range of applications. Currently it is supplied as a small standard surveying tool that surveys the hole as it is lowered and retrieved by the wireline at speeds over 100 m/min, making it very suitable for diamond core drilling and RC drilling. Non-continuous survey is also possible, supporting blast hole surveying and foundation drilling. Support for other applications, like overshot, core barrel head and core orientation will soon follow. 

The DeviGyro comes equipped with a rugged handheld device and is operated by a user friendly Android application.The communication between the instrument and the handheld device is wireless and also functions through the pressure barrel due to Devico’s patented antenna technology.

The data from the DeviGyro passes through a complex processing algorithm that ensures the accuracy and repeatability is always high, independent of the drill holes direction, inclination and position. An automatic and stringent quality control with a pass/fail criteria gives the user additional confidence the survey data is of the highest possible accuracy.

North Seeking Package
Combined with the DeviAligner (surface & underground) or DeviSight (surface) the DeviGyro
becomes a very powerful north seeking package that secures superior accuracy even in high latitude
locations. See respective brochures for further information on DeviAligner and DeviSight.
