                                                      EM  38

Designed to be particularly useful for agricultural surveys measuring soil salinity,the EM38 can cover large areas quickly without ground electrodes. Based on the same patented induction principle as the EM31, the EM38 provides depths of exploration of 1.5 meters and 0.75 meters in the vertical and horizontal dipole modes respectively.

Very lightweight and only one meter long, the EM38 provides rapid surveys with excellent lateral resolution. Measurement is normally made by placing this instrument on the ground and recording the meter reading. Digital meters are located on the top and the side of the EM38 for the horizontal and vertical dipole measurements. Continuous or station measurements can also be taken from a standing position using the optional carrying handle with trigger and cable for connection to the DL720 data logger. In this mode of operation 3000 data points can easily be obtained in one hour.

The EM38 has proven very useful in many geotechnical applications such as in archeology where use can also be made of the inphase component giving a measurement of the soil magnetic susceptibility.


                                                    EM  34

The EM34-3 is a fast, simple to operate, cost-effective instrument for the engineering geophysicist, geologist and hydrogeologist alike and has been particularly successful for mapping deeper groundwater contaminant plumes and for groundwater exploration. Using the same patented inductive method as the EM31, the EM34-3 uses 3 intercoil spacings to give variable depths of exploration down to 60 meters. With the 3 spacings and 2 dipole modes (horizontal coplanar as shown and vertical), vertical electrical soundings can be obtained. In the vertical dipole (horizontal-conplanar) mode the EM34-3 is very sensitive to vertical geological anomalies and is widely used for groundwater exploration in fractured, faulted and weathered bedrock zones. In regions of particularly high cultural and atmospheric noise the higher powered EM34-3XL improves the signal to noise ratio by a factor of 10 at the 40 m spacing and by 4 at the 10 m and 20 m spacing. The EM34-3 comes complete with an output connector for digital data logging with the DL720 as well as input ports which can be used with a rechargeable battery option.


                                                       EM  31
The EM31-MK2 is an updated version of the standard EM31 with the data  logger now incorporated into the control console. Ground conductivity and  in-phase measurements are read directly from the data logger screen. The data logger is readily removed from the console for easy data handling or, if preferred hand carried during the survey. The EM31-MK2 maps geological variations, groundwater contaminants or any subsurface feature associated with changes in the ground conductivity using a patented electromagnetic inductive technique that makes the measurements without electrodes or ground contact. With this inductive method, surveys can be carried out under most geological conditions including those of high surface resistivity such as sand, gravel and asphalt. The effective depth of exploration is about six meters, making it ideal for many geotechnical and groundwater contaminant surveys. Important advantages of the EM31-MK2 over conventional resistivity methods are the speed with which surveys can be conducted, the precision with which small changes in conductivity can be measured and the continuous readout and data collection while traversing the survey area. The in-phase component is especially useful for detecting shallow ore bodies and buried metal hazardous waste.


                                                EM  39 & 39S
The EM39 provides measurement of the electrical conductivity of the soil and rock surrounding a borehole or monitoring well, using the inductive electromagnetic technique. The unit employs coaxial coil geometry with an intercoil spacing of 50 cm to provide a substantial radius of exploration into the formation while maintaining excellent vertical resolution. Measurement is unaffected by a conductive borehole fluid or the presence of plastic casing. The instrument operates to a depth of 500 metres. The combination of a large conductivity range, high sensitivity and very low noise and drift, allows accurate measurement of subsurface conditions; typical applications include groundwater contamination monitoring, groundwater and mineral exploration, and general geotechnical applications. The 4-conductor EM39 probe can be used with many available borehole logging systems or with Geonics dedicated winch and console system. Measurements can be either recorded with the DL720 digital data logger, or viewed in real time using the EM39RT program with field computer.


                                                    EM  61
                                       Advanced Metal Detector
The EM61, one of the newest instruments from GEONICS, is a time-domain  metal detector which detects both ferrous and non-ferrous metals. A powerful  transmitter generates a pulsed primary magnetic field in the earth, which induces  eddy currents in nearby metallic objects. The eddy current decay produces a secondary magnetic field measured by the receiver coil.  By taking the measurement at a relatively long time after the start of the decay, the current induced in the ground has fully dissipated and only the current in the metal  is still producing a secondary field. The responses are recorded and displayed by  an integrated data logger.The EM61 detects a single 200-litre (55 gal) drum at a depth of over 3 metres beneath the instrument, yet is relatively insensitive to nearby cultural interference, such as fences, buildings and power lines. The response is a single, sharply defined peak, greatly facilitating quick and accurate location of the target. Depth of the target can usually be estimated from the width of the response. The system can be pulled around as a trailer with odometer mounted on the axle to trigger the data logger or it can be carried by a single operator with a shoulder harness.


                                      G858 Portable Cesium  Magnetometer/Gradiometer
                                              A 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 cesium 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 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.
