    The Native Heritage(NH) Magnetometer from Heritage Geophysics offers the exploration archaeologist an unsurpassed combination of high sensitivity cesium magnetometer, coupled to a high accuracy GPS, and delivered with a magnetic mapping package to accurately model and locate areas of interest. The NH Magnetometer is an excellent choice for archaeology exploration, gold and placer development, even those looking at old treasure maps.

    The Native Heritage Magnetometer allows the operator to quickly acquire a high-resolution walking survey and easily generate a magnetic anomaly map of potential mineral zones. The NH Magnetometer is designed to operate in the harshest conditions you will encounter, from scorching sandstorms to arctic blizzards. The rugged and field proven console and cesium sensor never need factory recalibration or adjustment. Continuous data acquisition with integrated GPS yield faster surveys allowing the operator to map large areas with ease.

    Gold exploration surveys for placer deposits benefit from the NH Magnetomer's high speed, low noise and high sensitivity. It incorporates a WAAS/EGNOS enabled NovatelT GPS for accurate survey position and operates world wide. The system includes free processing software providing data profiling or contouring for in-field or laboratory analysis.

    This low-cost cesium vapor magnetometer system offers archaeologists and survey companies the best total field magnetic survey tool available. A graphical interface makes survey design and data acquisition quick and efficient. A "Simple" or "Mapped" Mode uses line numbers and known staked reference points to define the map parameters. Or the user may use the integrated Novatel Smart AntennaT GPS for mapping positions automatically. Position information may come from an external GPS, from regularly spaced fiducial marks input by the operator or both. At any time, the user may switch to "profile" mode to observe the last 5 data lines as stacked profiles.

    Data is collected by the NH Magnetometer in up to 5 separate survey files and transferred via high speed RS−232 data link (or USB with converter) to a computer for further analysis and map generation. The full featured graphical data editing program MagMap2000 is provided to allow repositioning, realignment, GPS smoothing, data filtering and interpolation of the data. After editing, the data is formatted in either Surfer for Windows or Geosoft formats for further plotting and analysis.

    Speed and Efficiency

    The NH Magnetometer data acquisition offers either continuous (automatic) or discrete station recording. Data quality is uniformly high and lower costs are inherent for most projects due to the high sampling rate of the instrument in continuous mode. This allows the operator to survey an area at a fast pace, covering as much as 10 times more area in a given time period than other magnetometers.

    Reliable, Rugged & Low Cost Design

    In addition to its speed and sensitivity, the NH Magnetometer is also reliable, economical, and easy to use. Electrical connectors on the sensor have been eliminated in order to increase reliability and reduce setup time. The internal firmware is streamlined to include those features important for mining exploration.


    The concentration of magnetic minerals often varies with geological formation or chemical alteration and can indicate disturbed structures or fired clay shards. A primary application of the HR Mag is surveying for heritage sites, native settlement sites, and other artifacts. It can also be used for local environmental studies such as mapping waste sites, locating buried metal drums and storage tanks buried pipelines, well-heads and other ferrous structures.

    Digital Quality

    The system produces raw data of the highest quality. Data is digitally recorded in compressed form in high capacity RAM and later transferred to a computer for permanent storage and processing. Sensitivity, resolution and recording rate of the cesium magnetometer are user selectable as well as mapped survey grid coordinates or GPS position data. Data storage is sufficient to record 8 hours of data at the maximum rate of 5 Hz. Battery life is approximately 8 hours powering both the Magnetometer and Novatel Smart AntennaT GPS.

    MagMap Software

    cesium magnetometer image

    A complete software package called MagMap2000 is supplied as an integral part of the system and provides:

    • Transfer of the raw magnetometer, base station and other survey data to the client PC.
    • Standard corrections for position errors, transients, and time varying errors (diurnal).
    • GPS track plot with adjustable smoothing and independent point editing.
    • Repositioning, linear interpolation and format of corrected data into X, Y, Z or Latitude/Longitude ASCII columnar values for use with Surfer for Windows, Geosoft or other client supplied contouring programs.
    • Conversion of GPS to UTM coordinate system using a selected Datum.

    In addition to the standard MagMap2000 download and editing software, Heritage Geophysics is pleased to offer MagPickT, a full featured potential field analysis package with excellent profile and contour map generation capability. MagPickT can perform source body inversion, reduction to the pole, upward continuation and a variety of other transforms and gradient extractions. We are also pleased to offer a WindowsT version of CSAZIIT, a world total field map, field inclination and sensor orientation program for performing surveys worldwide in any survey direction. MagMap2000, MagPickT and CSAZIIT are available on our website for free download. Manuals for these programs are supplied as internal documents in PDF format.

    Novatel Smart Antenna

    cesium magnetometer image Accurate data positions are as important as accurate magnetic field measurements and Heritage Geophysics is pleased to include the Novatel Smart AntennaT as an integral part of the system. This small light-weight, all-in-one GPS Antenna and electronics package is WAAS/EGNOS ready for <1.5m positioning. The Smart AntennaT systems is installed on a non-magnetic back pack and carefully screened and degaussed for minimum magnetic interference.

    The Smart Antenna is designed to be quickly assembled and installed on the backpack, with special mounting studs and a cable wiring harness for data and power distribution. The storage case allows the main components to be stored as a unit providing minimum assembly at the job site. The storage case is a rugged reusable fiberglass and aluminum travel case with handles and wheels for easy transport.
