I am a big believer in knowing you detector, I currently run two of the best selling detectors on the market (DFX and Explorer SE) that holds there own against each other fairly well and while knowing both ok, I can still dance circles around them with my old Garrett ADS III that I've used since the early 80's. Knowing the machine is KEY, inside and out with every sound and creek it makes still brings new finds. Servicing the unit is also important. I just received mine back form East Texas Metal Detectors (BrokenDetectors.com) where they tore it down, cleaned and serviced it and sent it back good as new all for less than 80.00. True, the machine, if bought today would not be worth that, but the point is you have to know the detector to make the really good finds and while there is no doubt that I will surpass the ADS with the newer machines in the future, for now the Old Friend is still top dog in the relationship department (besides the wife), at least for the time being. So I guess the moral of the story is that the new technology is only as good as you know it.
