Portable Caesium Magnetometer/Gradiometer and Professional Magnetic Mapping System the G-858 MagMapper uses a graphical interface to make survey design and data acquisition quick and efficient. Various modes of operation allow the user to custom design a survey grid for their particular needs.

The operator also has the ability to view his/her position on the grid and the current data profile during the survey. Sensitivity, resolution, and recording rate of the caesium magnetometer are user selectable. G-858 data acquisition offers either continuous or discrete station recording. The high sampling rate of the instrument in continuous mode allows the operator to survey an area at a fast walking pace. A wider search radius can be achieved by using a horizontal transverse gradiometer configuration.

As a result, over-all costs are inherently lower while data quality remains high. The G-858 is designed to interface easily with standard computers and peripherals. Geometrics encourages clients to provide their own processing computer hardware. Upon the client’s request Geometrics will provide a complete and fully integrated processing station at a nominal price.

STANDARD FEATURES:

• Single or Dual Sensor Modes – Easily go from a single sensor survey to either a vertical or horizontal gradiometer survey.
• Low Noise/High Sensitivity – Pick up the smallest changes in magnetic field.
• Fast Sampling – Save money and time on large-scale surveys; detect the smallest objects.
• Low AC Field Interference – Survey next to power lines when necessary.
• Easy-to-use Interface – Useable by inexperienced personnel.
• Rugged and Reliable – Weatherproof. Survives three-foot drop onto hard surface.
• Ultra-stable – No need to calibrate sensors.
• Long Battery Life – Each battery pack allows for 6 hours of surveying with single sensor and 4 hours with gradiometer.
• Optional Ergonomic Backpack & GPS – Upgrade to a complete survey system at any time. Provides more comfort during and after survey.
• Optional Non-Magnetic Cart – Attach two or more sensors to our MagCart for large surveys looking for near- surface features.
