Overhauser Magnetometer sale

For a limited time you can save thousands off the new price of a GEM Systems GSM-19 overhauser base station or rover magnetometer. Fast sampling rover (GSM-19W overhauser) magnetometers are currently CAD$11,850 and base station GSM-19 overhausers are currently priced at CAD$9,000. Overhauser magnetometers have a sensitivity of 0.02 nT and are ideal for base […]

UAV airborne magnetic surveys. Off the shelf and ready to go.

“let’s strap a magnetometer onto our UAV. Easy. We’ll make millions. Millions I tells ya doing UAV airborne magnetic surveys!!”   Get in line people. I have fielded one call/email per week for about two years from people wanting to strap a magnetometer to their toy plane. At this point I may sound a bit […]

Coal magnetic surveys. Ultra-high resolution ground magnetic surveys for the coal industry.

Coal magnetic surveys are usually done at an ultra-high resolution. That is, with a line spacing of 10m. However the best ground magnetic data I have ever seen was over a gold prospect in Western Australia. The explorer was interested detecting mineralized structures trending east-west AS WELL AS north-south dolomite dikes intersecting the mineralisation. Ground […]

Modern Mag is now the premier provider of ground magnetic surveys in Australia

An independent geophysicist recently compared datasets from Modern Mag and the supposed ground magnetic industry leader over the same coal tenement.   The results “were a caning” in the words of our most senior operator. The independent consultant wrote: Modern Mag have provided a superior service on this occasion [dethroned industry leader]  needs to provide […]

Modern Mag is exclusive GEM Systems Advanced Magnetomer supplier in Australia and New Zealand.

Modern Mag is now the exclusive supplier of GEM systems equipment in Australia. The price you pay us, is the same manufacturers retail price (MRP) you would pay GEM Systems in Canada. Buying locally means the sales commission stays in Australia and Modern Mag can provide fast and experienced service and support. Buying direct from […]

A compact, lightweight and reliable magnetometer backpack

Ground based magnetometer systems haven’t changed much in 12 years. The most recent change was in 2001 with the inclusion of a GPS in most magnetometers when selective availability was turned off. This greatly increased the efficiency of surveys since only one operator was required to conduct a survey and they could walk continuously without […]

A ground magnetometer survey gone bad. Very bad.

A news report from Tsodilo Resources (TSX:TSD) on July 22nd 2013 caught my eye: A total of 63.70 line kilometers [of ground magnetics] was covered during the month of June as area totaling 2.53 km2. The expected monthly target is 360 line kilometers for the month and the shortfall is largely attributed to machine malfunction […]

Is the potassium magnetometer (GSMP-35) right for you?

The GEM Systems GSMP-35 potassium magnetometer is an optically pumped potassium vapor magnetometer. The GSMP-35 is also known as the “k-mag” just as Cesium magnetometers are know as “Cs-mags”.  As of August 2013, GEM Advanced Magnetometers is the ONLY company offering these magnetometers to the market. The GSMP-35 is the most sensitive magnetometer commercially available. By […]

Caesium Magnetometers. When Sales and Science Collide.

Modern Mag has created a backpack that can replace the standard backpack that ships with a prominent American Caesium magnetometer. To design this backpack I had to study and understand the Caesium magnetometer specifications. I have used this magnetometer many times in the past (my university owned one), but still wanted to check the latest […]

Airborne magnetic surveys using unmanned aerial vehicles (UAV) and lightweight potassium magnetometers.

Airborne magnetic surveys using unmanned airborne vehicles need geophysical equipment that is lightweight. GEM Systems now sells an option for a lightweight electronics box case for the GSMP-35 “k-mag”. Optically pumped magnetometers have lightweight sensors, but the electronics boxes can be heavy due to the case material and thickness. Any internal frame that binds two […]
