PI gold detector with real ground balance

[anto22]

In this video: https://www.youtube.com/watch?v=9wcn5wEJ3HA I noticed the detector's tone goes higher at the endponts as the operator swings it left and right. It may indicate poor or no Earth Field balance.

Yes, that so. Probably the video was done with turned off ground balance.

Is your method of ground balance original or known?

What is the resistance coil ? With commander coil 11 inch consumption is very high output warms tremendously to be able to flex pcb ! ?
Uses 2 x microcontroller !
He sent me a friend part of the scheme device ??!!!

Pulse delay is not necessarily.Yes, it will work on the beach. Which beach you have mind, and did You have any experiences on that beach with other Pulse Induction detectors?

i know delay is preset but how many uS, on that beach i use a white's tdi.

[anto22]

I think that TDI has about 60 microseconds first simple

[anto22]

the coil is 300 uH standart commander coil mono or double D

[anto22]

I use 1 microcontroller only
The ground balance metod is very similar minelab

I believe it's actually 10us delay for the first sample.

No not at all, there is no problem with EF, that video is mine, the sound on the video has become a little unsynchronised as it has gone through 2 conversions to get on you tube, The original file is many megs is size, I converted it to WMV to reduce the size, but still took 20 minutes to upload and then you tube did its conversion, so the sound is a bit out of sync, you can wave the coil around as much as you like and no problem with EF, and you can wave a fridge magnet over the coil with no problems, this PULSE machine ground balances very well in all the testing I have done on Victorian gold fields so far, and its super easy to ground balance.

AND with the ground balance turned off its deadly on coins at the beach.

Excellent info 6666, thanks for the field testing and basic review.. Look forward to hearing more.

yes Tdi is 10 microsecond,
this detector ?

[Orbit]

yes Tdi is 10 microsecond,
this detector ?

Right you are interested in how it works or how made ?

[bernte_one]

interesting Project
could be the next kit i would buy

[Rom_1]

i just want to know the delay ?

This Pulse detector is it as good as a tdi set in 10us at the beach with gb off to gold jewelry hunting ?
