XPLORER™ MAGNETICS
There is no substitute for resolution. Benefiting from low-level survey flying, dedicated low-noise aircraft, a non-magnetic composite boom platform, high speed synchronous data sampling and gradient sensor configuration, XPlorer™ is the most advanced gradient magnetic system on the market.
The XPlorer™ system offers three distinct advantages over competitors:
- Significant improvement to magnetic and radiometric data quality due to low survey height
- Tighter drape results in improved terrain following - ideal in areas with topography
- Ideal for high-resolution / ultra-high resolution surveys and target block follow-up projects
- Ideal in remote places where access to serviceable airports is limited (e.g. field camps)
- Improved safety
ASTAR350 B-series helicopter platform:
- Unique composite rigid boom mounting results in lower magnetic noise.
- 13 m horizontal sensor separation enables measurement of the horizontal magnetic gradient which is then incorporated in gridding algorithms:
- Better representation of line parallel features
- Improved spatial positioning of discreet targets (e.g. kimberlites)
- Overall equivalent to flying at a tighter line spacing

Fixed boom mounting & horizontal gradient measurement:
- Custom built DAS enables highly synchronous high speed sampling using a Rb atomic clock
- Magnetics stored at 20 Hz (~ 2m sample interval vs ~8m for standard fixed-wing @ 10Hz)
- Radiometrics stored at 2 Hz (~ 20m sample interval vs ~ 80m for standard fixed-wing @ 1Hz)
Hard triggered high speed data sampling:
The XPlorer™ system has proved robust in a variety of environments with consistently high daily production rates ensuring rapid delivery of results.
