Help with AT pro NEL Big coil 15x17

Post by Detector-Boy » Fri Jul 08, 2016 5:43 pm

So, I have gone over some land a few times with the standard coil.. it is as clean as can be.. My new 15x17 NEL coil came today, so I decided to go back over the land just to be sure :) but..

The damn thing is ridiculous, I ground balanced it on like 1-3 sensitivity as per instructions but can't get it silent soon as i am ready to detect and I go above 5 sensitivity the machine is falsing on grass blades... I have un plugged and re plugged it in about 10 times aswell so its not the fitting, I have also tried a factory reset

So in the end I was running around with a massive coil only running at 5 sensitivity, instead of the normal 7, so in essence I aint gaining any depth as I have to run it on such a low sensitivity it wipes out the depth gain, so what is the point in the £200 coil?

Any advice before i lose the plot/will entirely?

Hello Detector-Boy, its very important to post your topic in the more relevant forum as it will gain more views and hopefully get you an answer ::g
I`ll move your topic from general chat to the metal detector coils forum at the MDF.
