Golden Mask Deep Hunter Pro3 SE is a pulse induction (PI) metal detector, designed to detect deeply buried medium-size and large metal objects. This machine has both manual and fully automatic ground balance, and uses frame coils for deep search (should be used by two persons) and round coils with a stick to be used by one person. The Deep Hunter Pro3 SE has new electronics, compared to the Pro3, that allow the SE to outperform any other pulse detector of this class.

The type of the objects are identified by two LED lights - red for non-ferrous metals and green for iron. This model features a GM-developed Full AGEB system to compensate automatically for different ground conditions, and a new TRASH function (works only in AUTO mode) to select whether the machine reacts to large targets only or to large and small targets at the same time.
