Through the years I have owned several [size=small](more than eight)[/size] Compadres, both brand new or from a former owner. I don't care to own one again, especially used as that's were I had the most frustrations with that model. Why, because the Compadre has only one knob and all too often people have opened them up to try and get more or better performance from them, adjusting all the trimmer, even not knowing what the specific trimmer is supposed to do. Most of the time their 'interior art work' resulted in one messed-up performing Compadre with rearranged trimmer settings ... then they couldn't get it back to where it was so they traded it off or sold it.
I would say about six of the Compadres I had came my were in perfect-looking condition, new or 'as-new', but with messed up settings I had to deal with. So Yes, we know the Compadre was/is a well-intended low-end or entry-level detector, but it was shipped out with a fixed coil and internally set GB and other adjustments to be functional just as it came. If it lacked any external adjustments or features we would like to have, then it was better to just spend a little more and buy a model with the features and functions we really wanted.
Along comes the Mojave and it gives us the better features of the two former low-cost models. The Compadre's strong point, really, is the fact it has the full-range ED-180 Discrimination, with one single knob to adjust from All Metal Accept [size=small](to respond to iron targets)[/size] all the way up through the non-ferrous conductive range. That's the 'Simple' but very 'Functional' design of the Compadre that the Mojave also features.
Then there are the features of the Silver µMAX [size=small](microMAX)[/size] that provide an external Sensitivity control, as well as a coil cable connector to allow interchangeable coil capability. Two desired and important additions to the Compadre's broad range variable Discrimination. This, alone, make the Mojave the more versatile of both of those other detector models, and the Mojave adds one step more. It has the very useful or 'Functional' 2-position set Ground Balance toggle switch. That makes it better than the Silver µMAX and Compadre as well.
I liked what I saw in the new Mojave when first introduced, and after getting mine over a year ago I have had ample opportunity to work it afield, and even compare with the other Tesoro's, which left me pleased to have my Mojave in my Regular-Use Detector Team. I have tried the 6" and 8" Concentric coils, but left the standard 'Precision' 7" Concentric mounted as it works very well. I've hunted many tot lots with it and dealt with the metal structures and obstacles but was able to find tiny-sized jewelry. Like using other workable detectors, you just need to keep the Discrimination adjusted low enough to accept those lower-conductive targets and you'll find them.
