Noisey area that sens adj. does nothing???

[mcb613]

Has anyone ever had an area that has a smaller area of a large "quiet " area that has terrible falsing ? I have 2 sites that I cannot do anything with. The sens adj does nothing, as well as manually selecting a channel. Bth sites produce alot of early to mid 1800 coins and I need to hunt there... for obvious reasons. ANy thoughts would be greatly appreciated.

Is there any large power cables running underground? I have found several spots like that and found those cables to be the culprit. Not much you can do but fight thru it.

Hey hey I am new to this forum but not detecting. I have found a couple places that to me sound like what you are refering to. I was stumped pretty good as well and the site turns up a nice keeper every now and then. Well what I did was switch to all metal and see if it was the ground driving my machine crazy. I found that the area I was trying to hunt must have had an old wood building on it and was litered with just about rusted through square nails. In this case I desided I would hunt with little to no disc and go real slow, and I was able to pick the good targets out with not to much trouble. Not sure if we are talking about the same thing, but hey give it a shot it worked in my case. Oh and the detector was a Quattro that was known for its slow recovery speed, SLOW & LOW !!!!
Good luck.............

Ive hunted over ground power lines before and had to turn down the sensitivity to 10, gain 7... and maybe even auto sens. When you hold your detector in the air in AM are you getting falsing or is it in the ground? Try resetting your detector to factory setting and put the coil on the ground when noise cancelling. You might also try Ferr sounds since most of the EMI is in that area.

I'd try going to a small coil. That will kill three birds with one stone- heavy trash, mineralization, or interference. I've found a small coil at some of my sites with heavy mineralization in the past would clean up coin signals and calm a machine down, even getting better depth than a larger coil due to the conditons. The coil sees less ground and so the machine is able to compensate better. A small coil will also tend to pick up less interference if that's the cause, and of course it's going to seperate iron and other junk better with each sweep if that's the cause.

Was at the famous noisey site today.. The noise appears to be coming from normal overhead power lines, as the detector go crazy @ 3 ft above ground.

Also, I will try my SEF 6x8 for the "3 bird comment".

Just a 1895 V and 5 old buttons today.

Try going on a windy day when the wind is blowing from you towards the power lines and also at night or VERY early in the morning (3-5am) when the power load the lines are carrying is minimal.
