MagArrow Magnetometer

SKU: GEO-MAGARROW Category: Tags , , , , , , , , ,

The MagArrow is Geometrics’ first ever UAS-enabled magnetometer and it’s setting a new standard for UAS magnetic surveys. It is a robust and flexible system that can adapt to ever changing field conditions and new user workflows.

The BAAM.Tech Take

The MagArrow is simple to integrate into existing heavy-lift/long-duration crafts, it has its own GPS and IMU integrated into the sensor, it’s light-weight and runs for up to 2 hours on its own batteries (of which are hot-swappable).
