You didn't make a mistake. I have been using detectors since 1970. I have owned the Relco, Whites; Fisher; King Cobra; Teknetics; Garrett; Minelab to name a few. Right now I have both the Minelab Explorer II and the Tejon. When my Explorer I conked out last year I quickly bought a Tejon from Dixie Metal Detectors. The price was right and it was highly recommended by the owner. I took the Tejon back to my Civil war site and found over 100 minnies; eight half dimes and dimes, all pre 1864; knapsack hooks; spoons; buttons, to name a few. The depth was incredible and ease of use fantastic. The dual discriminators work fine, better than a meter. I just set the main discriminator on iron, and the second higher, (forgot the setting, sorry). When I get a target I flip the toggle forward and it goes into the second discriminator, if the target is still there I did it and it is good. When I replaced my Minelab late last Summer I was in a real hurry to get back to my site and hunt it and get all the deep targets. I was surprised when I didn't hardly find anything at all. The Tejon had cleaned the field out. Pluses are lightweight; very easy to learn; great depth; accurate discrimination; lifetime warranty and price. This detector is half the price and as good as the Minelab. Negative are poorly designed battery compartments; location of headphone jack (I'm a leftie and my the jack is on the bottom of the detector on left side), and that's it. Took the detector out today to one of my favorite Missouri spots, same field I wiped out last year and found one button; one .69 and one 1854 "o" dime in great condition. The dime was in an area littered with nails. I had hunted it many times and today caught the target and the coin. You will not be sorry for purchasing the Tejon. By the way, Travel channel had a show on metal detecting civil war sites this past week, the organizer of the three day hunt was using a Tejon, so that does say something.
