I am looking for my first metal detector, the only place I can start is an old dam that is drying up. I went up there a few times to do some fishing and allready found two gold rings, and figured that may be there are more. The dry parts of the Dam are mostly rocks and desertlike around. I would really appreciate if someone could help me out with some tips on what kind of metal detector I could start with. I have seen in some sites the Garret ace 350, and the price fits my budget but dont know if it is the right one for the terrain. I have heard that you can detect better on even ground, so I dont know if the ace 350 will be able to detect over rocks and be able to detect gold pieces.
