Overview
The ANT-7 is a compact, very low-noise induction magnetometer designed for surveys that need strong low-frequency performance while keeping antenna length to a minimum. It is especially attractive where a shorter sensor is operationally helpful, including use as a vertical or companion channel alongside larger MT magnetic sensors.
Where It Fits
- MT surveys needing compact low-noise magnetic sensing
- Configurations where antenna length matters
- Vertical channel acquisition
- Multi-sensor layouts alongside larger induction coils

Why Customers Choose It
The ANT-7 gives customers a compact low-frequency magnetic sensor without giving up the low-noise character required for demanding MT work. It is a practical option when deployment geometry or channel layout needs a shorter antenna.
