Naval Surface Warfare Center Carderock is using what they term a Mine Warfare Rapid Assessment Capability (mRAC) demonstrator which “is a man-portable threat detection and localization system that utilizes an ultra-sensitive magnetometer sensor package to afford operators the ability to conduct an exploratory wide area search more efficiently.”
Or, put in a more basic description: a quadcopter with a magnetometer array linked to an iPad, which is pretty cool. They bill it as working the 0-40 foot surf/littoral area.
Above video shows it in use at the Ship-to-Shore Maneuver Exploration and Experimentation (S2ME2) Advanced Naval Technology Exercise (ANTX) 2017 at Marine Corps Base Camp Pendleton, California.
