G-882 Marine Magnetometer
Very high resolution Caesium Vapour performance has been incorporated onto a low cost, small size, system for professional surveys in shallow water. High sensitivity at fast sample rates of total field measurements are maintained for all applications.
Features Include
- Streamlined design for tow safety
- Quick conversion from CG tow to nose tow, easy carry handles
- Highest Sensitivity in the industry, 0.004nT/root Hz
- Digital output, can be logged with MagLog™ software.
- Low weight, can be man handled
- New internal CM221 counter module, provides flash memory for storage of default parameter set by user.
- New Echosounder/altimeter option
- Zero phase lag on data
- True amplitudes reported
- Can be combined into gradient arrays, transverse, vertical or longitudinal
- Data from multiple magnetometers can easily be concatenated into a single data stream
