The 24k is a small gold specialist, excellent for finding small gold at shallow depths, you don't have to go far past one gram for the TDI to start performing well. The question is at what point does one beat the other. Mineralization, coils used, gold size are the main factors. TDI is a more versatile machine, goldfields, beaches or coin relic hunting. The 24k will see gold the TDI cannot, that gold will be small, in mullock heaps, crevices, mostly shallow. The 24k is not for ocean beaches or high salt ground.

Much more small bits of gold than the larger nuggets, total weights may be low but there is the fun factor finding the specks. On the goldfields the 24k would compliment a PI machine very nicely, hence my interest. The GMX Sport would be ideal for both general prospecting, fresh water jewellery coin hunting in swim holes, crevicing rivers and creeks. Western Victoria has been hit very hard by electronic prospectors, Eastern Victoria is worth exploring, it is mountainous and wet, most gold is alluvial but with smaller bits and smaller nuggets also. Perfect hunting ground for the GMX Sport. That's my plan for it anyway..
