i just got an se this spring and pinpointing was a big problem , here;s some advice i recieved, if you have the DD coil,, draw an imaginary line down the center of your coil from front to back ( picture it as a windshield wiper), it is hot in the center from front to back, your target can be anywhere along that 10 inch line. try this , once you center the target( get the highest pitch), slowly draw the coil back twords you , keeping the high pitch centered on the ( windshield wiper)< ( the imaginary line) until the target drops off ,.. the target will be immediatly in front of your coil and dead center on the line ( windshield wiper ) I did this and 26 times out of 26 targets i was right on . 1 barber dime , 7 wheaties ,(oldest 1912) a crotal bell, an old toy truck, a very old ,very cool key, and 11 memorials and 4 dimes , it really worked for me and changed my whole attitude about the new detector ,
