Trying to figure out 3030 display. User manual says horizontal is conductivity and vertical is ferrous so what is the number in the display preceding depth indication

excellent !Aluminum is another “highly conductive item”, just like a coin. This is where the BASICS of metal detecting come into play to try and determine if a coin is present, or it’s a bigger piece of aluminum. Watch the ENTIRE video.
Great video. The only thing I would add is with a 9" or smaller coil an object the size of a screwcap or larger will run the entire length of the EW DD coil while all coins smaller than a half will only run about 2" on each side of the NS rod of the DD. Since we are using an 11" in a trashy area, I'm assuming we are using disc coin mode along with manual transmission. This is when I wish we had a 9" coil. would be a little easier for detecting bottle caps and you could increase the gain a bit to make up the 1 or 2" depth loss. Of course a can or screw cap will mask most coins so just removing them is sometime worth it. ptThings like aluminum SCREW CAPS are a really hard deal, you’re digging them. They are the same conductive range, size and shape of a coin. It’s like a machine trying to differentiate between a pull tab and certain gold items...it can’t, so we have to use certain methods we know of, and accept the result of the rest. The more you “coin hunt”, the more obvious it will be that the target is a coin... or not.
Yes! Well put LT. I knew it wasn’t an “obvious coin signal” and perhaps I shouldn’t have called it that but many would chase that. Just knowing what a coin should do at various depths is critical, IF a person is going to dig in a disciplined and targeted way. If the argument of “what if it were this” were to come up, then that is NOT “disciplined coin hunting”! It doesn’t make chasing stuff like that piece of aluminum in the video “wrong”, it just makes digging it with the hopes it’s a COIN wrong.Great video.
