The Fisher F-5 is really a excellent choice for the money. Having said that, when I first acquired my F-5 I wasn't so sure. As much as I hate to admit it, I let Fisher Labs know I wasn't happy with the F-5 in no uncertain terms. To their credit Fisher Labs ( Mainly Felix "the man") bent over backwards in an attempt to help me out. Between Felix, his knowledgeable technicians AND this forum I eventually became aware of where I was going wrong.
Ground conditions and the availability of desirable targets is what it's all about. If the ground conditions in your area are not user friendly your learning curve with the F-5 will be quite peaky. The non existence of of desirable targets is self explanatory. As far as ground conditions are concerned they have a larger impact on how the F-5 or any other detectors performs than is typically acknowledged, from my perspective. In my area in the U.S. or native soil (no topsoil present) is very high in iron oxide and magnetite. In these conditions it is near impossible for my F-5 to detect a silver dime at 5 inches, via VDI or audio discrimination, even while set in the lowest discrimination setting of #1.
On the other side of the coin, so to speak, I have easily detected an IH penny at 8 plus inches in dark loamy soil where it blankets over our highly mineralized native soil. To be clear deep dark loamy soil is typical of soil that one would find located in good farmland. As a general rule this type of top soil has very low levels of mineralization such as iron oxide and magnetite.
So in my opinion: No matter how well you ground balance your F-5 if the soil you are hunting (by my measure) is considered bad (3 plus bars and GB at 78+) don't expect the magical 8 inches of depth on a silver dime. Generally speaking if your good dark topsoil is say 4 inches deep that's about it for fairly accurate and consistent VDI and audio target ID at that 4 inches of depth. By the same token if the good non-mineralized soil is 12 inches deep your detecting in the detectable depth is whatever you can milk out of your F-5.
My 2 cents. HH
