With 15 inch coil if there isnt any power lines or tower it will be no problem except weiht of coil is this right ?and how much depth it could be on a matel on air nerly

Aprox 50 cm for 1e coin size. In air. Maybe u can get more, but u will get into instability, chatering. 50 is enough, trust me.
Even if u wanna search for WW2 panzer tank, buried 2 meters in ground.

Lock at this vertion it was done in radiosoker fourm it seems perfect Https://www.youtube.com/watch?v=xXyIXFg2pKE

This is copy of Ultimate 13" coil from Detech.

10" is a good all round size. Normally fine near power lines

6" is better if there is iron about.


I have only been on one site that interference was a problem. Next to a electric railway line. Affected both coils. Been on another site were there was underground power lines. Was still detectable with the 10" but had to turn the sense down a bit.


I have tried adjusting the Rx capacitor. You can get more depth as in many YouTube videos air tests are fantastic. However it looses a lot in the ground and more unstable.

It is ok for 10 inch coil, but i mean 15" or bigger. Its terrible to work with this coil under power lines, towers...

https://youtu.be/pAkpdHhfOQg... Hello fellow today tried my IDX to the field. good expectations for the moment, seems little depth, 30 sm. ground 1 €. Nervous behavior up sensitivity

I mean, bigger coil is less imune to electromagnetic interferences. Cell phone towers, power sources, etc.

There is 2 vr insted a resister in down the board and one disconnect about ic lf347 and some change with resister value

Cdi i cant understand (less imune to IME)can u explain please ! coala say about T2 what do u mean of it is it another version or tresh 2

I mean that one in this site http://radioskot.ru/forum/14-2780-1

I saw this board long time ago, if u look better at pcb, there are no major change's. Most diffirence is visible from right - down corner (U4). I have last one pcb file from Eduardo which is posted here. Can attach here if u interested.

Not md4u i mean that in radiosoket by dexxter and so im folowing in post 1245 another a few days and it will be done

[Koala]

Not been following the md4u thread. Just had a quick look and the board in first post is the one I made.


translators aren't so good on that site. Translates the words but somehow the meaning gets lost.

Is there any defrence with a coby in a ru fourm

Thanx coala for replay with regards
