Thank you friend 😊 I know that other people has the same problem whit this detector and I hope to help to solve it 😉 BTW TX-850 is very good detector I like it

@@HoBByTV_The_King_Detectors Yes, this is a nice gesture. Thank you

@@HoBByTV_The_King_Detectors To prawda Dziekuje za Twoja pracę

Thanks 😄

heavily mineralized soil such as granite

I find this is better to do with a silver coin ring.. the ring would clip out in the ring orientation because the vdi is higer than 100 and only be visible on its side because it's less conductive from the side.. so what you do is you tune the ring face into range at 95.. it will still be miles away from reacting to graphite.. ❤❤❤❤

Yes all metal

I guess the direction is different for everyone, just get a ferrite and try it in one direction, if it doesn't work, turn it to the other side until it stops beeping and you're done. PS when it comes on the detector is set for heavy soil so you just turn it on and start turning the trimpot until it stops beeping and the device is set correctly.

I don't know about grade, but granite can also be used.The mineralization numbers on the display for graphite is 84 and for granite 82-83

@HoBByTV_The_King_Detectors big thanks for post I used a clamp on ferrite to calibrate my tx850 definitely works 💪
