Got my GPX secondhand from some bloke in South Island, said it had about 35 hours use. I believe him it looked clean and with little use, he looked to be selling up everything and shifting, also threw in a soil scoop, bag and control box cover.
Sometimes when I twist my body, move, or for no reason at all, but usually if I squat down the noise (hum) jumps by a factor of 10! If I was over a strong target this could be painful. Luckily I also have my volume at minimal (2-4, RX Gain 11, audio normal, Audio Tone 45, stabiliser 10, signal 16, target vol 8, response normal)
It feels as if there is a loose connection somewhere, except I've not been able to reproduce the disturbance, despite much twirling, squatting, arm flailing, cord tugging, jiggling, kneeding.
The effect can happen on normal ground far from the city with not target in area.
I auto tune, air tune, and ground balance regularly, my plugs are clean & screwed in tightly. My battery is at full power & I've not had issues with it.
It is not a major annoyance and the noise often drops back to normal after a moment, and I'm getting used to it.
I do have my cellphone with me, which I could leave at home to see if this makes a difference.
Keys, cellphone etc are kept in pockets on my left shoulder far from detector ( I'm right handed), I'm also tall so coil is kept at a good distance.
I've a spare battery that I could try, another power lead & coil also.
Don't think I'm accidentally pressing the quick ground balance button by accident, or going close to large metal objects.
On one of my nightcrawler runs I could go out in only my black longjohns to totally eliminate any personal interference.
