Reliability, Simplicity & Performance. Surface readout and memory capability on a unique solid state North Seeking platform.

The Champ Gyro SRO™ offers high speed high continuous survey capability at speeds of up to 50m per minute as well as singleshot, multishot or orientation operation.

All operations can be run in surface readout or memory mode providing unprecedented flexibility to survey the widest range of applications.

A robust intelligent design, low maintenance and cost of repair ensures the SRO’s cost of ownership is the lowest in the industry.

As with all Axis’ technology its remarkably simple to operate.

Run on E-line, the Champ Gyro SRO provides real time North Seeking gyro data to any surface PC or download data acquired in memory mode via high speed wireless communication.

Once powered up the probe requires less than 60 seconds to warm up before its ready to be run downhole. A 5 minute collar North Seek is all thats required prior to running high speed operation.

Alternatively, North Seeking singleshot, multishot or orientation measurements can be taken as and when required without the need for collar alignment.

Running on cable, encoder depth (e-line or memory) is automatically integrated with azimuth and inclination data throughout the survey.

The SRO’s North Seeking solid state sensors are capable of tracking slight changes in hole deviation thus providing a precise representation of the hole trajectory.

SRO can be used confidently to run drop gyro, on-rods horizontal, pump in surveys, orientation of motor or wedges and much more.
