Hey guys , I'm new to this board although I've probably been reading for a year or so. Next summer I'm going to my home country of Ukraine and right near my town there is a site where in 1709 the battle of Poltava took place. All around this area is a WW2 battle field so I'm worried about mines and stuff like that. Ive been reading around and it looks like alot of people here use detectors in the 700+ dollar range. Will a 200 dollar detector like the garret ace 250 still find old coins from the 1700's ? I don't want to buy a detector ,but not find anything because it is all too deep... And if I find a mine how would I distinguish it or just have the detector ignore it ?
