[QUOTE="Big Johno, post: 595444, member: 16872"] Hi Nenad, You made an interesting point that has raised my interest, point being use a target suspended above the coil being swept on the ground. I find that fascinating so today Im going to detect until I find a target, carefully measure the max height of the coil over the target, dig the target record the depth and add to the max height, then place the target on the ground and try your idea of sweeping the ground under the suspended target and see if the distances are the same above the ground as below the ground in undisturbed soil. I had never thought to try that, be fun. It would soon give credence to how accurate air testing is. Also as we all know so many variances make a difference to testing but if its just to use as a comparison on the performances of coils and machines then any method is OK really. Cheers Johno [/QUOTE]
