GDD MPP Probe will confirm the geophysical response of any rock sample. Instantly!
This unique handheld Multi-Parameter Probe instantly measures and records up to 10 times per second the magnetic susceptibility and the relative and absolute conductivity of your drilling cores, field samples, boulders and showings.

Looking to increase your I.P. crew daily production?
Do as GDD customers and use the latest GDD I.P. transmitter to increase your daily production by up to 25 %. By transmiting up to 4800 Volts/ 7200 Watts in very resistive ground, one will send up to 500% more current and get faster readings at the I.P. receiver. GDD I.P. transmitters are extremely reliable and backed by an outstanding field support.

Looking for a new IP receiver with up to 32 channels ?
With 8 simultaneous poles/dipoles, expandable to 32, for dipole-dipole, the GDD IP Receiver is a new compact unit designed for high productivity resistivity and chargeability measurements. Among other things, it uses an external PDA.

Need extra power, voltage or current in your next PULSE EM survey?
Compatible with any Pulse EM system (Geonics, Crone, SmartV EM), increase current by 400% in a 4km loop by using GDD IP transmitter with GDD TRM. The TRM allows the transmitter to generate frequencies with an external signal generator. Increased current allows to detect new anomalies at greater depths. Developed and tested with the largest Canadian producer of nickel in Sudbury.

Don't know where to start, too many targets to drill or not enough money to drill all the conductors?
Use the Beep Mat to find and sample near surface conductor inexpensively from which one will choose the best assays to drill. This powerful miniaturized electromagnetic survey instrument instantly detects conductive and magnetic outcrops or boulders hidden under up to 4.5 meters of overburden or snow. The new BM8 can now store data and GPS location up to 10 times/sec.

Looking for an alternative or complement to total stations or GPS when measuring elevation profiles in woody or hilly areas?
Don't cut vegetation and decrease your gravity survey costs by 50%! The GDD Chain+Level does the job faster and cheaper than total station. The reading is instantly given with high precision. Inexpensively level between benchmarks established with high-precision GPS or a total station. The largest diamond producer worldwide has adopted this technology in South Africa!

Mining ore and dreaming of increasing tonnage, ore grades and reducing dilution?
Use the GDD SSW probe to define quickly and inexpensively the ore grade and waste limits by surveying your blast holes every 10 cm. Do like Falconbridge and the largest Canadian producer of nickel in Thompson: reduce dilution, increase ore grades and tonnages by getting a 3D model of the ore grades and limits. This technology is based on the conductivity and magnetic susceptibility.

Mining non-conductive ore and dreaming of increasing tonnage, ore grades and reducing dilution?
Use the NEW GDD Photonic Probe to quickly define the ore grade and waste limits by surveying your blast holes. Define every 2.5 cm the limits between sphalerite, chalcopyrite, gold and the waste. Reduce dilution, increase ore grades and tonnages by getting a 3D model of the ore grades and limits. Developped with the help of CAMESE and Development Economic Canada.

GDD innovates in Diamond Exploration Busines !
At the request of DeBeers Canada Exploration Inc., Instrumentation GDD inc. has developed and tested a real time density measurement system for LST heavy liquid using pressure sensors. This unique system is now in production at DeBeers laboratories allowing to measure in real time liquid density from 1 to 5 SG at temperature of up to 120°C.

Looking to rent other instruments (MaxMin, Gravimeter, Walking Mag, etc.) or for an experienced crew to do geophysical surveys (Beep Mat, Chain+Level, etc.) ?
Give us a phone call, GDD advice is free and you will have access to experienced geophysicists to help you define the right type of survey with the appropriate instrumentation. In Canada, our free phone line is +1 (877) 977-4249.

Looking to upgrade your skills with a field course or else?
Looking to learn how to localize EM conductors under overburden and snow, how to use the GPS to localize the samples and put the results on map, how to use dynamite to blast and sample your targets or how to stake your claims?
GDD can learn you how. See Freewest case !
