Magnetic

Excel owns and operates GEM Overhauser GSM-19 magnetometers. The GSM-19 is a total field quantum magnetometer integrated with a high accuracy GPS antenna acquiring real time GPS data. These magnetometers have an absolute accuracy of ± 0.1 nT and a resolution of ± 0.01 nT. Magnetometers are single sensor instruments that measure magnetic flux densities (in units of Tesla) at a point in space where the sensor is located. Magnetic surveys are designed to satisfy the client's needs; whether the survey objective is to acquire high sensitivity continuous data both airborne and on ground, high sensitivity discrete data or repeatable accurate base station readings.

Applications:

• Evaluate large areas for mineral bearing ore bodies and oil-bearing sedimentary structures
• Locating and mapping buried ferrous metals, utilities, UXO, abandoned wells, landfills, trench boundaries, drums and USTs
• Mapping geologic structures & archaeological footprints

Advantages:

• Low-cost
• Non-intrusive
• Easy to operate
• Detects ferrous metals (iron or steel)
• Hand carried on ground
