Equinox Is Multi Frequency? Or Isn't It? Is It Not? It Is! Isn't It?

Interesting thred...even though I understand virtually nothing you guys are saying I get the feeling that it feels good and I already know that my detector is fast and finds lots of stuff which is all I really need to know. Having been trained in a medical field all I can say is that those graphs...if they were an ECG would represent something that is about to die  :biggrin:

Equinox .. : Patent :US7432715 , US7579839....Minelab says in the patent that Tx emits from 2.5kHz-80khz - but the RX side receives frequencies from 5khz to 40khz and all over 40khz is filtered ...

A few days ago I made measurements and compared all Equinox programs on Old 1.5.0 and New 1.7.5. Firmware, So soon to publish it ...I have also scanned the frequency of 5,10,15,20,40kHz ....
 

With patents, the game is usually to "stake" as much territory as you can by making the claims as broad as can be successfully prosecuted. That is, while gadget may faithfully represent the patented invention reduced to practice, that does not mean that the gadget embodies the full extent of the patented invention and claims. Here, it seems as though the "multifrequency" claims of patent US7432715B2  would apply to use of two or more frequencies: "In one embodiment, the metal detector generates two or more frequencies sufficiently different of each other so that effective ground rejection and target discrimination/identification become possible (multiple frequency metal detector)."

For comparison, I take measurements from the Whites Spectra V3 Detector:

 Spectra V3: 3F -multi -TX normal..
