So with subtraction the higher frequency will be less sensitive to low conductive targets like small gold? Link to comment Share on other sites More sharing options...
Geotech Posted January 28, 2022 Share Posted January 28, 2022 When you subtract the frequencies for salt cancel you end up with a composite signal that is used for raw detection. Yes, this signal will be less sensitive to target near the salt notch. 1 Link to comment Share on other sites More sharing options...

That makes sense thanks. so for the addition it’s opposite, in that you add a frequency like 40khz to make the signal more sensitive to a desired target?
