Hi I have a question Gpx is a multi frequency device right? In order to make same coil work with different frequencies you should change the coil itself resonant frequency for example by changing the capacitor connected to coil. How it's getting done in gpx? Are they using different capacitors or other ways?
The whole detector and coil pulse width difference is totally inefficient and is not optimised to the coil, in enhance mode there at pulses of 6 us and others over 200 us, just make sure the coil resonance is above all the different tx frequencies.
@@DetectorMods you mean that the coil only need to matches the highest frequency? In that case the lower frequencies must be a division of higher frequency? For example 2khz, 4khz, 8khz and so on

No, the whole putting of energy into the coil is done by brute force and ignorance.
@@DetectorMods that kinda explain why gpx using too much battery
@@drghz3783 I have an idea, well, you are onto it as well.
