Reliability, Simplicity & Performance

Champ Gyro SRO

Surface readout and memory capability on a unique solid state North Seeking platform.

The next generation Champ Gyro SRO offers high speed continuous survey capability at speeds of up to 200m (656ft) per minute as well as singleshot, multishot or orientation modes of operation.

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, it’s 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 min in-hole gyrocompass is all that is required prior to running in high speed continuous mode.

Alternatively, North Seeking singleshot, multishot or orientation measurements can be taken as and when required.

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

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