Hello treasure hunters. I am a collector of Indian artifacts. In one of the fields I look we have started to find copper artifacts from the Old Copper Culture. While surface collecting we have found a copper celt, 2 spear points and an awl. A couple of years back I talked with a few copper collectors and they recommended the 1266X. I got one but only used it a few times. I found a copper awl along with hundreds of nails and other junk. I know I need to spend more time to learn how to use it properly but another friend has a Whites with a "needle" that shows the strength of the signal. He says copper will pin the needle and all iron will barely make it move. I think I need something that will show the "ID" of the item. The Coinstrike shows on the screen +'s and -'s. If I go to an area with lots of iron junk and a few larger copper items will I be able to tell the difference somewhat easily? Or should I maybe be looking at a CZ-3D? From what I've heard the C$ is a tough unit to learn but it seems to be the best. Can anyone with a little more experience give me some advice?
