Just showing how the blisstool works in badd EMI and its disq on bottle caps you see i had to lower the gain to 0 for best results under the power lines and the one under the drivway it still did good , but is not recomended in the owners manuel , wich says it is very unstabe around power and rich uban inviorments so they warn you best used in the farm field and woods i would say but i have got good results in the ball fields and trashy spots as well [video]http://www.youtube.com/watch?v=2Aj0RmdVWmM&feature=plcp[/video]
