The Minelab GPX 4500 is the latest detector from Minelab specifically designed to find gold nuggets. It has a lot of features that previous GP and SD units do not have and from all reports runs with a very stable threshold which is important. Also, Minelab has improved the discrimination circuitry to the point that it is actually useful.
A lot of finding gold nuggets comes down to belief. Belief in the detector you are using is a big part of that equation. If you aren't finding gold with a GPX4500, it's not because of the detector!
