[QUOTE="dazza513, post: 109563, member: 3800"] I was standing on a hill right next to a mobile phone tower and the spp was in the car, hmm so I got it out and switched it on... ok nice and smooth, ground balanced nicely on hot'ish ground and no warble or hiccups either hmm... I grabed a tiny bit of junk I'd found the day before and waved it over the coil with the detector coil down on the ground and nothing??? hmm got another small piece out of my pocket (slightly bigger) and it just found it, I moved the freq pot a quarter turn and tried again and the signal was way stronger... has anyone else tried this? the spp had dumbed down to stay quiet but I had no real way of finding the best freq setting as the noise reduction hid the emi so good! gain was at 7 and there was no hint of any emi warble or chatter even when I maxed the gain. any ideas ?
