Surface Readout

DS’ high-speed high-accuracy gyro services are deployed from our modern, well equipped logging vehicles. Ideal for larger scale, high value drilling programs where productivity and verifiable accuracy are of the utmost importance. Call-out or dedicated on-site services available.

DS utilises the very latest in north seeking technology, the Champ Gyro SRO which offers incredible reliability and performance with high speed continuous survey capability at speeds of up to 100m per minute as well as singleshot, multishot or orientation modes of operation – in real time.

Why use DS Gyro Services?

  • Proven track record with most major mining companies in Africa and easily the most experienced Gyro service provider in Africa.
  • Comprehensive “closed loop” quality control system applied to every survey.
  • DS land surveyed and certified calibration stands either on-site or at our South African, Botswana or Ghana facilities.
  • Web-based client access to DS dataServ data management portal
  • Flexibility to deploy DS geophysical, geotechnical, hydro-geological service via same logging vehicle.



DS provides call-out and dedicated on-site services using Axis’ next generation Champ Navigator north seeking solid state memory gyro system. With onPoint ART technology DS can survey both underground and surface boreholes of any size, depth and inclination in any application including:

  • High speed continuous surveying via rig cable or DS wireline
  • Multishot surveys and orientation of wedges or motors (incl. vertical orientation)
  • End of hole rod pull survey (replacing surface EMS rod pull surveys)
  • Underground horizontal pump-in or rod pull surveys
  • Fast, efficient and reliable blast hole surveying

DS is the Authorised Distributer for Axis Mining Technology in Africa and has established Axis certified calibration stands as well as holding back-up and consignment stock of all Axis Gyro products allowing for 24 hour replacement of damaged tooling.

Only DS can ensure reliable performance, on-time, every-time.
