[QUOTE="Goldpick, post: 93522, member: 1695"] You can discriminate out metal beer bottle caps, but in the process you also risk discriminating out $1 coins and pennies, hence I only have crown caps knocked out, and not the screwcaps. The way I can ID targets by size is usually by looking at the ferrous/conductivity figures, and then cross check them with the depth reading. If you have a very good conductor with low ferrous reading, and the depth is very shallow, most of the times it a large piece of aluminium junk, get the same figure deep, chances are it is a silver pre-dec, both might read 00:28. Plus you can also check in VCO pinpoint mode to get an idea of the physical size of the target, anything with a broad but high conductivity signal is usually a flattened can or the top section. That last hunt I did had a lot of smaller aluminium pull tabs and ring pulls due to having jewellery accepted in the discrimination pattern I think the CTX can actually display the target size, but not 100% sure on that.
