Any DIY PI/VLF MD that can detect up to 2-5 meters depth?

[kt315]

i see you want to waste your resource just on cigarretes. do not see a perspective to answer.

Hi kt315

Can you share the dp rev5 latest schematic?

[kt315]

latest

pleasure

[ramin]

Thank you anatolij

I see The changes are c27 c29 and r46 (with rev3 schematic)
is there any other change??

[kt315]

r45 and r46 were in old circuit. i deleted them because nobody uses a headphone they were for. no need.
also, i had noticed people have a problem to find out the resistor with low value 2.2Ohm. now this problem disappeared
c27 an c29. modern polar capacitors have less sizes vs old ones so set 1000uF x 16V.

reporting you smallest changes in DP board had (HAD) done and soon i will order new pcb batch revision 5.0.
i promise you that EVERYONE will get this board with 2-5 meters of the depth on cola can/banka.

Dream on. Not even in air.
But you can shoot and upload some videos to convince us. Hahaha.



And to you bhatu - I doubt you still will read this because your last contact here was 09-06-2019:

You better forget even your 2 meters depth because anything below already just 70cm is very hard to
reach, dig and find for a single person and its hard to deal with the needed 1 meter coils.
Some of my finds were already 1meter deep - a concrete-fundament of a cut down power-line-mast.
I smashed the blueish cement with a 10kg sledgehammer to get the steelbar out - no way! *laugh*

Working with a 1 meter coil also means to find first 100 not so deep junk objects!
I wish you good luck to clear them. *laugh*

Best you bury first something 1 meter deep in your garden and then test it!

My recent Pulse Star II diy with 44cm coil; cola can at 70-80cm.
Not bad at all.
Deus can do same distance with 22cm coil (in air), but PSII can go up to 2 meters (in soil) on larger objects, while Deus is stuck to max. 90cm even at largest objects.
Apples and pears again, right! lol
Delta Pulse can do similar, but is a bit inert and slower response than PS II.
PSII is somewhat advanced and lot much easier to handle. Faster and agile.
Overall all those are quite alright machines, if used for what those are purposed.
But to reach real 2 meters in soil... that's hard!
Target must be MASSIVE and mostly of iron.

this is not mine problem to dig 2 meters depth

In my opinion this change causes more current to speaker
This may increses the sound of deep target

What is your opinion?

[kt315]

my opinion learn all documentation i gave. look all files. current in speaker is small

This depth of 2-5 meters for cola can is fraud. After you buy the board you will never find the original chips. Also you will always fail to find correct values for components. The detector will not perform and the designer will start to insult you every time you ask questions about low depth. This claim about depth is scam. Better stay away.

I read all the posts on delta pulse thread from first to last
Now i am building dp

[Vadim18]

Why not? If we connect two DP in series we can reach even 6 meters at least!

Hi anatolij

For r23 to r26 i dont have access to 0.1% telorance resistor
Can i use from 1% telorance?
