How about it, the triangle is beautiful, the truth is about the detector, how much experience do you have about it, because I really take it as high as the terrain allows me whenever I take the 4 foot frame, because really the ferrous will respond more faster and deeper the noble metals go to a shallower depth than these for your area that you demonstrate the frame is perfect I walk in hills and very few areas I can afford to use only the 58X48 centimeter coil and I don't like it because the response to small objectives and the frame is more about what we are looking for
