HeliMAG - Stinger and Tri-Axial Magnetic Gradiometer
FromGeotech Ltd.
Aeroquest operates two helicopter-borne magnetometer systems. The first is the tri-axial magnetic gradiometer system (TAG) which employs high resolution optically-pumped magnetic sensors with unique 3D sensor geometry for more detail and definition in gold and other mineral exploration surveys.

- Stable platform for low noise recording
- Highest available airborne spatial resolution
- Lightweight for flying in rugged and mountainous terrain
- Compensation of mag data to monitor and remove platform-induced noise
- Accurate topographic drape flying
- High data sampling rate
- More accurate target positioning
- Good performance in challenging terrain
- Detailed definition of structure and small sources
- Enhanced definition of complex structures
- Actual gradients for improved cross-line gridding
The second system is a stinger-mounted magnetometer system which employs the same high resolution magnetic sensor mounted on a boom. The stinger system is best suited for ultra-high resolution surveys in moderate to challenging terrain. Surveys can be flown with a line spacing as tight as 20 m and with a sensor height of less than 10 m.
