Re: NogginPlus 250Mhz for sale $8,000

Depth penetration of GPR is dependent on soil conditions. S&S website has some excellent resources here: https://www.sensoft.ca/products/noggin/frequencies/#Noggin250 and here in the FAQ under "How deep can GPR see?": https://www.sensoft.ca/support/faq/ Where I am from we generally have either silty...

Re: ERT under high voltage lines

Some utility poles/pylons leak line voltage down the ground wire. This messes up the apparent resistivity calculations. In my experience, about 1 in 10 poles or pylons are leaky enough to mess up resistivity measurements, but utility companies don't care about such low levels of line loss.
