Hello room, Just wanted some insight on the mine lab x-Terra 505. I want to know about its ground balancing and do you think it will work along a creek or river for gold nuggets? Iv seen one site that list it as a good choice for prospecting. My question is do you think it has the same, less, or more ground control than the garret gold scorpion? Or can you compare it the any other cheap gold detectors on the market today? I would like the 705 but I go to college, and don't really have the funds. Also what about the first detector for a person like me... Thanks Jess
