Swat--
The reasons you aren't diggin nics is(well on my Tesoro Bandito anyway) they are in the same discrimination range as 14kt rings(small to medium in size-a large gold ring is different)wadded foil,some lead,and just below pulltabs. The other posters were correct in that they are the least dug coin--why??I got notta clue,maybe whores in Hell cost the Devil 5c!! Anyway to find nickles and 14k rings , as you increase discrimination look for a very sharp null (where the sound cuts off). Tabs,foil,and the like will be broken or scratchy right at the end.A nic or 14k will be there one minute, the next increase(in descrim) its gone.If you ain't findin nickles your passin up 14k rings.Plant a test garden with nics,foil,14k ring and a tab.Learn the slight differences then nics will start showin and so will your rings. There are variables to this, machine makes,soil moisture,close to trash, and of course if theres no nickles or 14k where your huntin....... it happens!!!LOL-----------resurector
BTW-check out my newest post-- I got both 5c & 14kt
