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 […]

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 […]

How to walk straighter and further with less effort when conducting ground geophysical surveys.

Some walk the line straighter than others. Walking straighter lines when conducting ground geophysical surveys increases the production l-km in a day. Alternatively, if there is a fixed amount of work to do in the day, then straighter lines means less walking and less stress on the body. Walking straight in thick vegetation is never […]
