The detector is very noisy over iron mineralisarion and will drive you nuts.
The pulse timing is set for the machine to run quietly in salt water conditions.
Over black sand it is fine. That said; It is an all metal detector and will find gold in the right ground conditions but is not a detector I would use in the gold fields.
THe main claim to fame of PI metal detectors was that they did not respond to iron minerals and that is true up to a point but when the pulse delay is set for salt water hunting the detector would respond to metallic iron and iron mineral.
The Impulse is hot on iron , gold and silver in salt water and wet beach sands and ship wreak divers liked this detector for that very reason.
