The nox called the merc at 2 inches deep at 20 I had high tones set from 19 and up and nickels open at 12 to 13 the ctx called it iron except one sweep would give 12.43 more accurate ID than the 20 the nox called it but I don't think I would of hit it with the ctx it was a small window .The nox found the coin with every sweep at 20 there were nails with it had to bring down the ID because it could not separate it .
The other 2 silvers came in at 26 and 21 both had nails with them ctx called 12.43 on one and iron on the other however it was a very small window to get a ID and only one way again .
As far as nickels I am throwing in the towel the nox calls almost all tabs and a lot of caps 13s and 12s so I marked 10 solid 13s and 12s with the nox the ctx called them caps and pull-tabs one it called 12.13 which turned out to be a beaver tail which is one of the only things I dig or some tabs . Not like the nox which just loves to call everything nickels the only targets I marked were 12 to 13 maybe the 6 will work better don't know but I am done digging nickels with the 11 inch coil . It might find nickels deeper but not at a fairground unless I take up mining aluminum .
I will still dig nickel signals but not at a cap and tab infested area with no depth reading to tell me how deep they are . If I get back to the fairgrounds I may just mark the nickel hit's with poker chips and rescan them all with the ctx save some digging .I will be running park 2 next time to see what the nickels well do but park 1 is not a nickel magnet at all . sube
