The wife being out of town and the internet all to myself became dangerous last night.......I ordered the coiltek digger coil! Really anxious to get it and try it out. So now that it's on the way what can I truly expect when it arrives? I have the stock 9" 7.5 and a 10" 7.5 DD coils----what will I notice as a distinctive difference between the digger and the coils I have? In short, is there a significant difference or a difference to be learned? My hope is that it will "latch on" to silver and copper a little better than the coils I have. Comments appreciated!
