Transient EM System

The FastSnap offers high productivity and versatility in the field due to the option of using two mobile receivers synchronized to the transmitter by internal GPS (inbuilt GPS comes standard on all transmitters and receiver units). This allows multiple receiver configurations to be collected simultaneously without cables between transmitter and receiver units. The system is light weight with Transmitter and receiver weighing in at 3kg and 2kg respectively. Fast shut-off time of 2 microseconds for a 25m loop and 10 microseconds for 100m loop comes standard. The FastSnap comes with a 10 amp Transmitter although transmitters up to 200 amps are available. The system is backed by a comprehensive software suite including full processing and 1-D Inversion Capabilities. See full details on the FastSnap page.

Magnetic Susceptibility Meters

The magROCK is a highly sensitive, rugged magnetic susceptibility meter.  It operates at a relatively low frequency of 750Hz to provide a more true magnetic reading without interference from conductivity effects.  Low frequency also permits deeper reading into the sample.  Output is via USB cable.  See full details on the magROCK page.

Alpha also represents ZH Instruments with the SM-30.  The SM-30 is ideal if small size and taking readings at the very low end of the magnetic susceptibility scale are important.

Ground Penetrating Radar (GPR)

The Mala Geoscience range of GPR systems include a full spectrum of GPR applications from very shallow concrete investigations (using 1.2, 1.6 or 2.3 GHz antennas), to deep geological targets (using frequencies of 25, 50 or 100 MHz).  Mala's ProEx console supports all of the shielded and unshielded antennas as well as borehole antenna of 50, 100 and 250 MHz.  Details of the Mala range of products can be seen on the Mala GPR page.

Total Field Magnetics

Geometrics have a full range of magnetometers for ground, airborne and marine applications.  These units include caesium and proton sensors.  These magnetometers can be configured with GPS for positional information.  The software package, Magmap 2000 can process and display the data.  For further details see the Geometrics Magnetics page.

Radiometric Instrumentation

Radiation Solutions in Canada, produce a range of spectrometer units which range from handheld to vehicle and airborne systems servicing all areas of the mineral exploration market.  The RS-230 Super-SPEC provides 80% equivalence of a 3x3 Nal crystal pack in a 2x2 crystal size.  See details on the Radiation Solutions page. 

Seismics

The Geometrics range of seismographs caters for a full range of geophysical applications.  The systems go from 12 channels to 1000 channels.  These units can be used for seismic refraction, reflection and surface wave investigations. Further information see Geometrics Seismic page.

Alpha also represents ABEM Seismographs. 

Resistivity

ABEM manufacture a range of Resistivity Meters including the Terrameter SAS 4000 and 1000 and the new Terrameter LS (see photo), for automatic resistivity and induced polarization imaging.  These units can be used for various applications including groundwater mapping. For further details see the ABEM page.

The Geometrics OhmMapper system can be used for speedy resistivity surveying. more

Borehole Logging

Mount Sopris Instruments (MSI) in the USA has a wide range of borehole systems from small portable systems (300 metres capacity) through to the large units (1,800 metre capacity).  MSI has a full range of probes for mineral exploration and groundwater investigations.  Software is also available for processing the data.  See details on the Mount Sopris page.  

Conductivity Meters (Frequency Domain EM)

DUALEM in Canada have developed a range of Electromagnetic (EM) geophysical instruments for conductivity surveys of soil, groundwater, minerals and bedrock, and detection of buried metal.  The patented DUALEM coil geometry permits simultaneous results at up to 6 depths and with automatic calibration.  Further details at the Dualem page. 

GPS and DGPS

Alpha has  developed complimentary DGPS systems for the geophysical instruments being sold.  The Novotel DGPS system is the one of choice with satellite or ground base corrections.

Software

Alpha has available an extensive range of processing and interpretation software for all types of geophysical applications.

Full details of all the available software are included on the Software page.
