Well, I went out to the picnic area that I like to hunt yesterday afternoon. ( My specialty is getting gold... from soccer/baseball/football fields and picnic areas). As usual I start out with a barrage of pulltabs and chopped up pulltab pieces. What I am looking for is numbers that " stick out"..............from the common numbers reocuring..In this kind of hunting.... you have to get a "feel" for what the junk comes up at. In this case there were a lot of 5 to 8 ranges.... then quite a bit of 12 to 15 but very erractic. Some of the chopped tabs jumped from 9 to 28....... those were easy as they are screaming.......don't dig me!!! Then I got into an area of tight 7 to 8 and 4 to 7 readings and finally a couple of solid 11's and 12's..............these turned up to be folded over pulltabs parts. But in there ; was a fairly solid 9 to 11 reading.............good sound about 4 inches deep. In the Sum mode it locked in at 9 to 10. The confidence barks were more splashed ...probably due to the targets shape, as it is not round. I dig it an up comes an 14 K Eagle pendant with a small diamond weighing in at 5 grams!!! All of a sudden the 4 hours of hunting and 72 pieces of aluminum in my pouch are irrelevant!!! I go home a happy man. The Cortes is " without a doubt" the best jewelry unit in all my years of hunting, and I started in 1974!!! I've owned at least 30 different detectors..............and no I do not sell Tesoro !! To get the most out of the Cortes....I insist you do this; for 3 hunts..... you "will" be very surprised!!! Set the disc at the halfway point between "min" and "iron" . Set the sensitivity to "4" and sweep the coil at a good 3 inches above the surface. Do "not use" the standard coil....... it just won't work well using this technique. I prefer the 7 inch concentric or the 5.75...... recently, I passed this info to a friend who lives in Bakersfield, and he was shocked at how much better his Cortes operated. Even though I am in a medium to higher mineralized area...... I don't go for the widescan coils as I need the better disc abilities that the concentric coils can provide. . In this type of hunting I rarely dig gold deeper than 5 inches!!! Depth is not paramount here, what counts in this type of hunting is......Target ID...and super discrimination abilities. Cortes has it in spades. Enjoy the photo.
