do not take expensive lineup options, it makes no sense, it is not worth it at all for the price. A very large overpayment. If at all you will need this device. unless for a pit or a beginner, then it will go
Pros
don't even know
Cons
rings on any millimeter jbon that you will never find. A lot of phantom targets, you will dig for a whole day in vain, until you begin to react only to a ringing coin sound with significant numbers on the monitor. Too big a price scam for the sake of profiting from suckers, masked by imaginary "nishtyaks" in which there is no sense and benefit.
