Metal decting around powerlines. question.

[nc-joe]

What effect to power substations with a lot of high voltage above ground power lines have on metal detecters?

I have located a spot that would have ALOT of pre 1940 coins and jewelry, but the location is now home to a substation.

hmm...good question, I would'nt mind hearing the answer to this one...

Turning down your sensitivity helps, if you are getting alot of cracking, chirping, and cross talk.

I've tried around overhead powerlines and get so much interferance that i cant detect but I never tried turning the sensitivity down I'll have to try that Thanks

High power voltage lines produce high magnetic fields. Thus, they tend to interfere with electronic equipment. I know they play havoc with amatuer radio.

By "home" I hope you mean it's in the close vacinity of a sub-station, and detecting INSIDE a sub-station.

From my experience, it won't work. Too much EM interference.

I have not to this date run across any detectors that operate well in these areas........period. Turning down the sens. helps some, but all detectors react differently. My advice is to just go somewhere else, or dig up and sift the area.

I have a couple BH's,I can't turn down the sensitivity enough to detect in areas with a lot of electro-magnetic interference.Sorry.

I have also had to turn the sensitivity down to zero. I think you loose too much depth doing that. I have never been able to detect around these.
There is a ghost town near me in a plowed field where the power lines cut across the field. I have found that I need to be about 2 blocks away in order to detect.

I use a DFX and am able to make some adjustments which include decreasing the sensitivity
in a couple of settings as well as using a smaller coil.

This has worked for me under power lines however I do give up some depth running like this.

I really have not done any detecting near a substation but this is an interesting question.

Just play with your settings some and see what you come up with, you may or may not be able
to run the machine but without at least trying you'll have to give up the area.

Be sure to go over your equipment manual closely and even contact the manufacturer and get some
ideas from them.
