Gday, Ive got a 4500, and Im not really very experienced with it, although, Im confident that Im setting up pretty right.
The ground up here is pretty hot.
I know at least 4 2300 owners, who all find gold regularly in the same general area that i work. 2 of them are also pretty inexperienced users.
I got the 4500 keeping in mind I intend to use it in area,s other than the Pine creek Area, QLD , WA and other area,s.
Most of the gold found in the area Ive been working is shallow, and sub gram to 2 gram with the occasional bigger piece.
From what I can see is this, NO other machine comes close to the 2300 for finding small gold in hot ground, the 7000 would be the next closest followed by the 5000.
The 2300 is one of the easiest, if not the easiest machine to set up and get out there finding gold.
I would recommend you get the 2300. Again, I got the 4500 with versatility in mind, but I know that the blokes who use the 2300 rarely if ever do a trip with when it all falls in place, and Im not completely goldless, but those 2300,s are freaks.
