Iam using the mxt all the time now,nothin fantastic as other users report ,but it goes deep,finds very small items and i am getting more comfortable using it.My question is,why am i finding nickles between 18 - 24 range I thought the machine would be more exact. Rusty nickles read differently and can be anywhere in that range at least on my machine.It may be the 6x10 i am using.I am looking for gold in all the wrong places.All i need to do is dig everything,which is an awlful lot of work,i'd be better off getting a job and buyin it 8/
