In this video I explain how I personally identify iron using the VCO tones on the Nexus MP V3. It takes time and practice, the machine has many small quirks that need to be studied and perfected. My Metal Detecting Blog otherworldlypo...
looks like an interesting machine with great iron id "built in". I do some similar things with the Legend in that when you run Pitch audio--signals have to climb in to give a clean repeatable tone. slowed down (also low bias) the unmasking that this gives is remarkable. a high tone that can't be pinned down is pretty much universal I call this an "emenating" response in that it's a reaction between the rion and the ground. great explanations in that these simple coil and usdio basics that tell you F from NF are skills that not many bother with but totally essential to becoming really accurarate. I was taught to look for "sets" of signal characteristics. and to ask "where is this target?" to prompt this kind of broad based examination. its alwmost comical to watch some trying to id iron by ear or otherwise and failing (YOuTube) --simple basics win every time. good luck, clive
Done some more testing myself with the pull tab and gold conundrum, and found out the resistivity of the pull tab is in front of the gold so when you eliminate the gold on discrimination, the pull tab still rings out, hence impossible to knock pull tabs out and still get gold, I did it with my Tesoro but it still holds for any detector.
