Wondering if there is any other detectors that display the concetration of iron/black sand in percentage or some other number scale when searching besides MXT and GMT.

are you talking about a GROUND reading, or a TARGET reading ?

The Fisher F-75 gives a magnetite reading (Fe3O4). It tells you whether there is a lot of iron/rust under the coil.

Upper right beside the battery level. Higher/more bars = more magnetite.

Charlie , I seen that in some videos only time I ever seen it registar was after they would ground balance . It looks like it stayed at how ever many bars it was ground balanced at . Does it change as the ground changes ?
thanks for your time

Yes. Also for old steel bottle-caps. At least in my local soil.

In fact, if you get a suspect hit pump the coil (do not squeeze the GB trigger) and see if the Fe3O4 scale jumps. That can be a tip-off it's a steel bottle cap.

Why would you want anything other than an MXT or GMT? Whites is the way to go. Plus you can't beat the zip zip. lol I wouldn't knock the gold bug. It in its own right is a fine cheapo detector. Maybe one of these days, if I work enough catalytic converter, I'll buy me a Goldbug2. ha ha ha. I have been having problem with my GMT and the first generation coil. I can't crank it up without it blowing my darn ear drums. Thanks again Dallas. :) I knew I should have gotten the darn tm808. Oh well, maybe one day I will get me one. :hello::notworthy:
