New-Sense Geophysics only uses the Scintrex CS-3 Magnetometer sensor for its airborne magnetic data acquisition. The CS-3 offers the highest sensitivity and lowest noise of any Cesium magnetometer on the market. The magnetometer has a sensitivity of better than 0.01 nT at a sampling interval of 0.1 second and has the capability to measure ambient magnetic fields in the range of about 15,000 to more than 105,000 nT. With automatic hemisphere switching and a wide input voltage range. In addition to having the maximum active zone and minimum dead zones, it also maintains the smallest heading errors, resulting the highest quality magnetic data collected.

The CS-3 magnetometer sensors are mounted within the heads of the helicopter and fixed wing tail stingers, as well as in wing-tip pods mounts for gradiometric work. The orientation of each sensor is adjustable, to provide optimum coupling with the earth’s field on reciprocal headings.
