Hi, is the only differences between the Vaquero and the Lobo SuperTraq about $220 and also the Vaquero has a Manual GB and concentric coil and the Lobo ST has Auto GB and a Widescan coil. Otherwise is the depth about the same ? The Lobo ST seems to be the better choice between the two to me because of the Auto GB ? (A concentric coil can easily be put on the Lobo ST for coin hunting.) What do you think ?
