All of pcb is work in the first bage and bage 50 and this bage no error l know some one a view days made the first one and it work perfectly no error

[CDI]

someone could send me a pcb finished with all the corrections made in idx?

Look's like nobody read the theme. Everything what u need i posted on this page, it's not that hard to find i think... How u will make metal detector if u read nothing and lazy to search...

Thanks CDI, let me do more research and compare

Hi all,
I would like to build this one cos most of members says its better and easyer than tgsl, could someone attach all build reference, pcb bottom print,pcb placement, size, part list, coil winding spec,etc?
I already read most of the pages and collect the references but im afraid i pick the wrong source and create a fail.

Thanks

I dont think so... Coil is much harder to make than TGSL, pcb is easy.
Here is my files about IDX, u have there correct and latest lay file, coil specs, vdi , etc... good luck.

With no coil the effect i have is in sens pot and valume but threshold not respond is that normaly or i have some mistake in my board thanks again

In all metal mode and no coil. Does turning the threshold affect the beep

[basellafe]

Whay mi idx still beeping and no effect in tunnig if l say there is no bad value and good soldering does bad coil couse this making it still beeping ..thanks for help

he say to disconnect c of q3 but if i do it there is no more sound can some one tell me the correct of this step

Well, nice mini review. I guess the pcb is correct. Do u have Minelab addon board attached to Bandido or stock version oscilator?

Stock plus home made concentric. Works perfect except a bit touchy on ground balance. Get it wrong and you loose 50% depth on large silver


Run my IDX for over a year. Not a great difference between them. Quite fields the IDX might just have the edge. Turn the discrimination down to zero. Dig all faint signals and thumb up the discrimination on larger signals. Too much discrimination and small silver coins on there edge are almost undetectable

Prefer the audio on the Tesoro. Could just be me can't really quantify it but somehow appears shaper over things like coins.


Bandido looses less depth if enough discrimination is used to eliminate those square forged nails. No motion all metal mode is really useful. Size and shape of target plus iron has a long slow rise and fall to a target and non ferrous much shaper edge to the sound.


Both good. If you look over at the MD4U forum you will see the Eldorado is well developed.



As an example I had an iffy deep signal with my IDX someone with a Dues and 9" coil checked it. Also gave an iffy signal.

[CDI]

Its a pre decimal penny that's badly corroded 10" down with a bit of grass on top of that. (about half its original thickness) a bit of iron about 12" away

Both the Bandido with 5.75" coil and IDX with "10 will pick it up quite easy. However with the IDX set with the same discrimination as the Bandido it only gives a slight crack that would not be a dig signal.

If I was to start again I might chose to build the Eldorado. Just been asked to find a horseshoe. The bandido does not go to 0 discrimination. Not a big problem as the all metal mode is great especially the no motion

Thank's Koala for answer. U didn't tell how much inches is buried penny...
Can u please post lay file for Bandido that u maked?
Ofcourse in tgsl/bandido thread.

I tried the golfnut mod of supple the Tx supply via 12 volts


Peak to peak goes from 16V to 20V.

No noticeable depth increase. No easy to test as you don't get exactly the same each time you test. Slightly different threshold, ground balance, discrimination or ground conditions all affect the result. I would say within testing errors

I have a penny buried in my lawn. With enough discrimination to exclude small iron its an iffy signal with my IDX running both TX's

However its an easy target with my Bandido with 12 volts peak to peak and a smaller coil.

Ofcourse in tgsl/bandido thread.
