Better for gold? Please clarify that statement. If you are looking for small pieces of natural gold, this won't help much IMO. This is the pinpointer I use, it works well, for metal detecting. If the target is really small, like a grain of rice (picker), these pinpointers won't find it easily. They find coins and objects of that size really well, but struggle on the tiny targets. You have to be right on top of the small target or it won't register.
Beware of cheap prices. Garrett does not let the dealers sell below a certain mark. This preserves the value for the dealer. If a dealer sold them too cheaply, then other dealers might not want to sell them, because they don't make enough profit, so the market becomes lopsided. This is bad for almost everyone involved.
Cheap price could also indicate a fake. Google: Caveat emptor.
Sorry to ramble on, I am getting old.
Best of luck to you sir!
