thanks, i moved to fb group

will try to add the mods step by step

hope i find good translator for arab to german or english

do you test a frame coil 1x1m or something bigger like original 25-30cm coil
which are the datas
maybe 10turns of 0,8mm wire with a dia of 1m (round shape)

which modifications on pcb, a variable wire damping resistor perhaps

Hi Bernard Use Google Chrome Translate to translate for you from Arabic to German I didn't make it, but now I'm making electronic components

I have to say that this circuit does very well on the beach, I was able to find coins at over 10 inches deep. I move slowly over the sand and listen carefully for small increase in the "click click" sound. I was surprised at how well it worked, it is very stable at the beach where there is little interference. My coil is not shielded. I set the threshold for just about 1 click per second, there I have best results.

Good video

after assembling working detector its time for some mods
but i am not sure which direction, deep hunter for big objects or medium hunter for coins and smaller stuff

Hi Watanabe, thanks for the answer, thats interesting that the circuit does not give false beep at the end of a coil swing
its a shame that you fell into the sea.
I have a lucas lab PCB that I am pretty sure I bought from Silverdog, maybe if there is enough interest he might do a short run of PCB's ?

Hello 6666, I am curious if you ever built out your Lucas Lab PCB for this detector?
Cheers

Hi no I have not built the Lucas Lab PCB, maybe one day

hello everyone
i wanna build polones (the polish pi) and i'm just confused with coils , i can't find any exact information on the forum
i want to make a 30cm and a 60cm coil and i don't know what diameter enameled wire to wind the coils
can i use 0.5mm for both?
or like... 0.5mm for 30cm and 0.75mm for 60cm?
this is my first PI by the way

thank you in advance guys

hi
for 30cm :
0.5mm wir 18turns 317uH


for 60cm :
0.5mm wir 12turns 329uH
0.8mm wir 12turns 304uH

hi
for 30cm :
0.5mm wir 18turns 317uH


for 60cm :
0.5mm wir 12turns 329uH
0.8mm wir 12turns 304uH

thanks a lot man, i appreciate it
for 60cm which one (0.5 or 0.80) do you think gives more depth?
