- Identifies magnetic influences detrimental to non-magnetic directional drilling and surveying equipment.
- Material found with hot spot (Magnetic anomaly) can be demagnetized and reconfirmed with a re-run to verify acceptable limits.
- In compliance with API Specification-7-1 which stipulates that the maximum field gradient tolerance are set to +5µT
- Sensitivity of 0.05µT
- Generally examined every six months
