Lithogen Geonics EM38-mk2 Comprehensive Tutorial with QGIS processing instructions

Target audience: anyone familiar with geophysical surveying but unfamiliar with the EM38.

Disclaimer: this is me. And Lithogen is my small business.

Shoddy troubleshooting video, but might be interesting to those in the industry :)

Beautiful instrument -- going into our museum.

From our fleet. Opened to do contact cleaning and maintenance.

I just kind of like it. Connector inspections -- something every geophysicist learns to be anal retentive about if they last long enough.

Anyone care to offer their interpretation on the data displayed? ;)

Tutorial video for my customers showing how to use the Sensoft Spidar GPR system for IceProfiling, assuming you're already familiar with the IceMap. (Shameless self promotion)

Whenever I dig up an old manual, I contribute to their very useful collection. If you have anything old manuals for old geophysical equipment, send them a note!

With apologies for the colour scheme (I'm so sorry if you're colour blind!). This is the lower layer of a two layer 1D inversion model, interpolated. Was playing with maximizing the contrast to try to find the foundation of the Richardson Mansion that existed on this property prior to it being bulldozed in the 70s and donated to the City of Winnipeg to become Munson Park. I'm pretty sure I captured it in the red square in the middle.

This is my EM34-3XL. Have you ever used one? What was your target? How many years/decades ago was it? ;)

Shameless OC. This is my video of a test I did for an R&D project -- the custom cart and GPR rig.

"The Earth's magnetic field is primarily generated by currents in the liquid outer core, though some geophysicists argue that an unexplained mismatch with models suggests that the Kinder toy contains a magnet."

Tl;dr: Pine Creek, MB investigates GPR anomalies at residential school, finding interesting things but no bodies so far.

Biting my tongue.... "about six inches"

I make little tutorial vidoes for my rental customers. Maybe it's useful to someone :)

This literally used to be my job -- so please ask if you have questions.
