North Seeking Continuous Gyro


Next Level Accuracy, Performance & Flexibility

Champ Navigator

Next Level Application Flexibility

Innovation in design and technology drives the Champ Navigators unique application flexibility & performance. Improved North Seek azimuth accuracy, continuous survey and rig alignment capability deliver value to any drill-hole.

Replace Conventional Magnetic Singleshot Surveys By Surveying Each Time You Pull Core With The Champ OSA. Increase Hole Positional Certainty Whilst Decreasing Costs Through Reduced Rig Downtime.

High-speed continuous survey capability is flexible to all drilling environments, underground or surface. Confidence begins at the collar with a measured North Seek azimuth and extends to the intuitive driller-friendly operating interface that supports effective survey execution.

Axis onSite™ wirelessly transmits surveys from the Champ Navigator’s handheld device via Wi-Fi or mobile data at the rig or project office, providing users with real-time access to critical drill-hole survey information. Data is accessible from the onSite™ Client Portal or from any geoscience or drilling workspace, delivered by Axis’ seamless and automated enterprise software API integration.

North Seek survey on the overshot as you pull core in B to P size rods with the Champ Navigator™ run in the Champ OSA™ fast descent 45.0mm (1.77”) or 42.0mm (1.65’’) slimline assemblies at surface or underground.

With a standard outside diameter of 36mm (1.42”) and a 35mm (1.37”) option available, the Champ Navigator is the only North-Seek Gyro which can confidently survey inside smaller rod sizes in the underground environment or inside small diameter RC innertubes.

Align your drill rig with the Navigator probe on surface or underground applications and use North Seek mode to substantiate collar azimuth for continuous survey referencing, or post collaring ahead of committing to the drill-hole.

Introducing the latest Rig Alignment mode

Navigator technology now supports a user friendly and auditable rig alignment function. Users can now quickly and confidently setup the drill rig into position and align the mast
