This is the new DEEPTECH VISTA GOLD  25 Khz METAL DETECTOR . In my opinion this detector is ideal for contamenated ancient sites .It has two tone id and a single tone id. If you are  looking for a detector that has iron id as well this would be the ideal metal detector for you.

The Deeptech Vista Gold metal detector has a boost so you can identify those deep signals, plus 2 recovery speeds slow and fast.
