Hello all, I am new the the Sovereign GT ( had it about 4 months) and still learning. My question is this , If I'm hunting with a slight threshold and it nulls out but there is a higher threshold on each side of the null does this indicate a good target ? I don"t get a high tone signal just a higher faint threshold.( like a deep target) settings are no disc. no notch, 1 oclock sens. I have tried digging these higher thresholds but I have only found junk, just wanted to make sure i"m not leaving the good stuff
