or even a "backup". I like to think of it as having a few "extras". Seriously, I do have several detectors, just as mechanics have more than one set of wrenches. Different tools for different jobs. Depending on how you hunt, where you hunt and what you are hunting for, having an "extra" detector isn't a bad thing. I've had as many as a dozen, at any one time. Currently, I have an XLPro with the 350 Snooper coil that I really enjoy using in nasty-trashy areas. At 6.59 kHz, that 3.5 inch coil separates with the best of them. Now, if Minelab ever comes out with a small DD coil at 3 kHz, I might have to retire that XLPro. I also have an Advantage for those times when I simply want to "beep and dig". Nothing responds any faster, runs any quieter, or hunts any deeper than my Advantage. The Advantage and TS800 coil is an excellent combination for combing an old bean field. For extreme target separation that requires a slow sweep, I have an MXT equipped with the Sierra HotFoot coil. If you are unfamiliar with that coil, it is a 2-inch wide X 9-inch long DD coil. As with the 350 Snooper on my XLPro, it ain't a depth monster. But the super narrow target "window" serves a purpose for me and the type of detecting I do. With all things considered, however, my X-70 and 6-inch DD coil combination is the one I "go to" a vast majority of the time. JMHO HH Randy
