EMI

[GeorgeinSC]

Yesterday I made a second trip to a tot lot where EMI made it almost impossible to detect over half of the lot. I had worked the area where EMI was the least the last time I was there. First time there I had taken the S-12 off and put the Tornado 10" coil on my GT but could not see any difference in the problems that the EMI was causing. Yesterday I put the S-8 coil on and still had the same problems with the EMI. Just experimenting with the GT settings I put it on "Disc" and "PP" and was able to work the entire lot with hardly any problems from the EMI. However when the street lights came on there was no place in the 7 acre park that one could get away from the EMI regardless of the settings on the GT.

Cool experimenting. The 12x10 for me seems more imune than any other coil I've used to EMI and mineralization. But yea, not only can you run at full sensitivity in PP mode in minerals, but it also seems to make it EMI proof. Only 1 site thus far did PP mode have issues with EMI, and it was VERY bad EMI that you hardly ever see.

Another thing to try to tame the EMI- Besides trying both noise bands, try turning Iron Mask OFF and turning on Silent Search. This will help buffer any instability of the machine. Also, sometimes Auto sensitivity will smooth out issues that no manual setting will, even the lowest.

Underground power lines for the street lights it dont matter what coil you use nothing will help . Jim

Glad you found at least some settings that work

There is a beach here in Tasmania that I would dearly love to work, my Sov GT and Safari both go into conniptions as soon as I turn them on in this location. I get a "wip,wip,wip" plus a back ground warble with the GT and just an unintelligible cacophony of electronic jumble on the Safari. The whole beach, about 500 yards is the same. Used to be a plant producing silicon carbide in a large electric furnace close by and the substation still exists. I don't know how this could possibly have a effect today. Sure is something there though.
