I was shopping around and decided to try a rf choke made from radio shack on my d2 coil lead near the control box. I have an intersection of 3 underground power lines in my yard and have not been able to run a gain of more than 3 and a disc of 80. I could not hunt within 4 (more like 10 feet) feet of the line without erratic behavior. I placed the rf choke on and could hunt within 4 feet of the line with a gain of 10 and a disc of 85. It also smoothed the target id all through my yard where I did not see the EMI. I found a nickel immediately after placing the choke at 7 inches within 4feet of the power line. I then found a cast iron horses head the size of a half dollar within 2 feet of the line. I have been over this area several hundred times and could not see these targets with any certainty till after the choke was in place. I also found a dozen clad pennies and copper washers that where on the surface.
The one rf choke I purchased was slightly to small and rather than cut the coil wire by forcing it on I removed the ferrite pieces and wrapped them in place with electrical tape. Closer to the control box the better.
It was the best $3.00 or so I have spent in months.
