Ah, but that isnt what Whites says. Though they do state that there are alot of harmonics involved, too many to analyze. However, they specifically stated that the DFX transmits 16 frequencies, not just the harmonics.

What about the DFX supposedly transmitting 16 freqencies and analyzing the strongest 2 of the 16 to give you the best information.
No, the DFX transmits 2 frequencies only. Everything else is harmonics.

Ah, but that isnt what Whites says. Though they do state that there are alot of harmonics involved, too many to analyze. However, they specifically stated that the DFX transmits 16 frequencies, not just harmonics. However, I will admit that their description of the method makes things, once I sat and thought about it, unclear as to means and method and why they would state that and then turn around and specify just the 2 frequencies being used. Are they simply trying to confuse the issue? I dont know. But if they are, why would it be necessary? Even with the 2 frequencies, its enough to make the DFX a very effective detector so why confuse the issue, which they have?
As to the SF having more more because of the power being split among the multiple frequencies, that can be adjusted by making more power available so that the same amount of power is available to the MF detector transmisions as is the SF detector.
Sure, that's possible. V3 includes a TX Boost that does that, at the expense of fast battery drain.

But isnt it true that most of those that do transmit MF do seem to have increased power supply requirements? I havent speciifically examined or analyzed the power supplies to see what the circuit requirements would be for each to last the specified amount of time but it does seem like the MF detectors power requirements are higher as well as them lasting shorter amount of times compared to SF detectors. The exceptions, of course would be the PI detectors, which are by their nature, another ball game entirely. Look at my detectorpro PI. Uses a 9volt. And lasts 30 or 40 hours. Then look at my Infinium LS and the power supply for it. Same type detector, though with differences. Main one is that the LS has additional circuits in order to provide the minimal target ID and discrimination. Hard to believe that those additions have such higher power requirements but that and the ground lock, I think, are the main differences between the two. Oh, let me not forget the single LED on the LS.
Maybe I am just missing something or just wandering in a circle. And maybe I am just being dumb as brick. Heck.
Thanks for responding Carl. I am really enjoying the mind fest. Its making me think and recover some of my old background. Stuff I havent thought about for years. Its clearing the cobwebs for sure. And If I am wrong, I dont mind one bit. I just enjoy the discussion. Hope its the same for you.
