that is lightweight (3lbs or less), has a visual readout of some kind, nothing fancy, + or minus VDI numbers would be nice or just some bar graph, or needle meter, two different tones would be nice for iron and non-iron. Doesn't even need discrimination per se. And, can get about 6-7" in bad ground. I need it for my wife and she likes some kind of visual like what's on the MXT, but she likes the lightness of the Tesoro Cibola. I've been told that the ACE 250 doesn't fair too well in our slightly bad Alabama dirt. Any suggestions?
