Modern Mag has developed a carbon fibre and aluminium backpack for use with GEM systems, Scintrex or a Geometrics magnetometer. This pack is lighter and much more comfortable than the backpacks shipped from the manufacturers. For example, students call the Geometrics magnetometer G858/859 the “rack of pain”! Comfortable A prominent Australian hiking brand has designed […]

Magnetometer batteries
Scintrex and Geometrics magnetometers require heavy sealed lead acid magnetometer batteries greater than 7.2Ah in size. In contrast GEM Systems uses lightweight lithium Ion batteries and SLA batteries only 2.2Ah in size. While the SLA batteries are conveniently built in to the console, they do however need to be protected against a short circuit against […]

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 […]
