Drilling Optimisation

Allows Drilling Operators to align drill rigs and survey instruments and more accurately measure drill hole collars.

The REFLEX NORTH FINDER APS™ (Azimuth Pointing System) is not affected by local magnetic interference. Accurate collar azimuth is vital and can have the greatest impact on the final end-of-hole coordinates. Geologists are able to use the REFLEX NORTH FINDER APS™ to pick up previous collars and accurately record starting dip and azimuth coordinates. The REFLEX NORTH FINDER APS™ features UTM and latitude/longitude coordinates, sub-metre GPS position accuracy, Signal Quality indication for more accurate azimuth and a long life battery providing over 10 hours of run time. Collar and directional data from the REFLEX NORTH FINDER APS™ is transferred via Bluetooth connectivity to a REFLEX Table.
