phrunt Posted September 13, 2023 Share Posted September 13, 2023 The bigger the coil the worse it is, but yes, high voltage lines can cause an affect many hundreds of meters away and the bigger the coil the worse it is. 400-500 meters would be within a range of possibly causing problems. You're on the right track using a DD coil over a mono which is less affected by EMI. And adjusting settings to suit the conditions will help. 1 Link to comment Share on other sites More sharing options...
detector Posted September 13, 2023 Author Share Posted September 13, 2023 i will try coiltek 22" DD. do you think XP Xtrem Hunter will have the same problem? XP claim it can cancel EMI: Frequency Scan (EMI noise cancel): Auto/Manual - 14 channels Link to comment Share on other sites More sharing options...
phrunt Posted September 13, 2023 Share Posted September 13, 2023 Best to ask that question in the XP area of the forum as XP Deus 2 owners will let you know how well it handles power lines. Many VLF's can cancel EMI, and have options like switching to single frequency to improve EMI performance, so generally there is usually a way to get around EMI on detectors like the XP without losing too much performance, however I don't think it will get the same depth as a GPX. 1 Link to comment Share on other sites More sharing options...
