I've done some detecting in the past with several types of detectors from really cheap one's I can't remember the name of to old White's lunchbox detectors and recent Garrett budget models. For the first time I'm getting really interested in the hobby and I need a detector. Currently I don't have one. Since my budget is low and I've heard great things about the Compadre, I've been thinking about buying one. However, I'm not sure if I should go ahead and save a little more and get the Silver µMax. The only real difference I can see between the two are the presence of a sensitivity knob on the Silver µMax. Other than that and the fact that the the coil is removable on the Silver µMax they seem nearly identical. Is the sensitivity feature worth the extra $95? I also know the operating frequency is slightly higher on the Compadre. I mean if I'm going to ever upgrade from the Compadre, I would just move up to the Vaquero. I also want to note that I prefer to buy new. Thanks in advance!
