[QUOTE="Jon, post: 16083, member: 717"] Best you can do to come close to real type scenario is to find a little erosion gutter or edge of some surfacing and then drill, somehow, a few holes at varying depths into the side. Did that with a mate a number of years ago to test out coils and new machines when they came out. When you dig a hole you can at times get what used to be called "hole slap" which can and does affect the target or perceived target sound. I have seen blokes dig holes and keep going deeper and saying "yep I can still hear it" when all they were getting was hole slap and the target was actually lost to hearing way before that. Some ground doesn't do that as bad as others but its something to be aware of. Best way to make sure its not happening is to wave the coil over the empty hole and be sure there isn't so much as a hint of false sound when you do. If there is it will affect the outcome. [/QUOTE]
