Minelab premium metal detectors are designed specifically for specialised detecting of gold, treasure or landmines. High performance gold detectors typically have Pulse Induction technology and are
optimised for detecting gold nuggets in mineralised ground. High performance treasure detectors typically have high resolution discrimination capability to identify, accept and reject different metals and the capability to work well in beach and salt water
conditions. However, all detectors will detect all metals, and many Minelab products are very well suited to All Purpose detecting.
The GPX-4500 (along with other detectors in the GPX Series) is a versatile high end
detector that is just as capable of finding deep relics as it is deep
The X-TERRA 705 Dual Pack is a great choice as a mid-level detector for all requirements. With specific Coin &Treasure and Gold search modes, it really is 2
