I've always wondered, do the tone, vdi, and notch ID all run separate of each other? Basically our F75's have 3 methods of ID, the tone, the notch, and the VDI which is great unless they are all connected such as a high VDI will automatically register a high tone, which will automatically register in high coin ID on the notch bar so basically what one tells you, the others fall in line automatically. If you guys get what I'm saying haha. It seems like this is the case because I don't recall getting say a medium tone, a high VDI, and a High notch etc. So it doesn't matter which method you use, the tone, VDI, or Notch, they are all saying the same thing. I could be wrong though but it would be much better if each id system used a separate method of analyzing a target so you get 3 true opinions and not one opinion displayed in 3 methods
