MagDrone R3 used to locate parts of North Star wreck

Hull remains of North Star break at Upper Columbia River

“Research Associate John Pollack and archaeologist Xenius Nielson made a total station survey of the [North Star] wreck while Sean and Tay Adams of 3 Points in Space Media used a DJI M600 industrial drone equipped with a loaned German SENSYS MAGDRONE R3 magnetometer to survey the river and locate two targets that will be investigated in the fall. Additional tests of the drone/magnetometer combination were made near Castlegar, BC where the wreck of a small steam tug was located. Drone magnetometers have proven to be very practical for rapid, shallow water surveys.”Source: https://nauticalarch.org/north-star-in-golden/
