Just a side note on the bliss disriminate, It is best on discriminating Iron and makes a broken signal or interupted sound on foils it will break up on them as well , so you can tell foil I was just out at a parkand was getting brocken signals that somwhat sounded good they turned out to be the broken off tabs from the ring pulls but the ring pull part sounded good but this way you will not miss gold , now in the UK whear some coins are a thin as a aluminum can they dont want to disq that out so the detector is kinda set up to really deal with Iron and really junk foils if you have cleaned up the 1st 8" of an old lot and want the 8" to 12" dime size targets the bliss will nail them, and quarters at 14" set your gain at 2.5 and a threshold of 6 and DD8 and DL at 4 you will be suprized how much deep silver you will pull out I am currently hunting a farm feild and i love the way it breaks up on Iron but when you hit a non Iron target it gives a dens uniterupted signal very nice I am not diggin alll the iron and wearing me self out
