Delta Pulse

[mohandes]

To kt315 the smart man who modify delta pulse successfully , i have question

what is the best for gold detecting ( jar filled with golden coins ) delta pulse of TM808 2 BOX METAL detector ?

is that true delta pulse or PI machine is not sensitive to gold like VLF metal detector?

i am trying to find this detector too , good depth good disc ,but yet not found
i am sure exist that detector we need but cannot find it, it is secret

if you know where an jar filled golden coins you do not need in a metal detector. you need in good shovel. show me the place and I will find you the jar filled gold coins
without Delta Pulse.

Hi koko22! KT315 is right, In my DP?, I used the of Bulgarian PCB a six pot not seven, i think the problem of your DP is not the supply voltage of all IC but try to measure if the supply voltage is present, second check the surrounding components of NE556 and LF357 for bad components or loss contact and fault pcb trace, third follow KT315 advice use o-scope for signal tracing...

hi, nowhere, no places. may be only a level on output of D6A is half of a source. if reference level is -E. mainly you have to use o-scope.
my opinion you do not get one side PCB smaller than turkish one side layout.

hi kt315
where are the places to measure DP by Voltmeter,and is there Other PCB one Sid for DP

hi

In a reply # 2232

[kt315]

any your comments suggestions on the placement? what to add or to change?

Thanks for Reply saromines ramil

The problem still exists if possible Instructs me to Measurement places in this photo
If possible, explain to me

where????????

thanks both guru

ok i make dp2 first(becuase i have not correct 2box pcb)

Hello, Mr. 315, I was producing DELTA PULSE, 40CM diameter coil, detecting a Coca-Cola cans in the air is only 70CM, 1MX1M coil job insecurity, so turn to you, it should be much inductance, resistance of the coil should as much, but I'd like to improve it with you, and strive to the maximum depth of the probe, such as replacing a better op amp, improve the supply voltage, filtering, peak detection, etc., but I electronic Technology Co., you can not help thinking, I change how improvements can help me draw a good circuit schematic diagram assembled according to me, thank you wasted your valuable time

on 40CM coil the depth on cola can is VERY LOW! ONLY 70CM! NOT SUCH I WANT TO GET 5 METER! hahahaha

DP sees some pieses of steel easily on 3.5 and more meters at bottom of lakes. but to say what sizes of the pieces is not be possible because its are hard for lifting.
in our wood DP with 1x1 m coil sees too lots of the targets in ground. very sensitive to metall at surface. so disc in DP (meaning the size) is not good
vs Deepers 10DD. the Deepers' pinch-off works more effective. but tuning on ground in Deepers is not so good, it has a feature to slightly float.

any one know about the max depth in soil by 1m*1m coil(more 3.5meters or no?)(maybe Mr kt315 know!!!)
regards

Once we here did some DP testings.
I remember one result we achieved with exactly 1x1m coil.
Piece of steel (machine of old truck, ~70x60x50cm) was buried at 3 meters in soil.
Delta Pulse (120pps) with coil 1x1m easily detected it at such depth, with strong and clear audio response, completely no doubts in clear detection.
Even more; coil was risen some 50-70cm from the soil surface and it still produce nice, strong and clear detection on mentioned object in soil.
So, practically we may say it was 3.5 meters detection.
That's what i remember good from that testing.

sorry, the schematic is sophisticated for your knowledge level in electronics... i am very doubt you can bring DP to an end... i still noticed you absoliutely do not wish hear people what they say... as you are blind or deaf... i say you leave LRLs' matter you ask me send pages from a book. i send you precession magnetometer book with very good detailed info - you ignore that and continue ignore all. you are the blank dead wall for all suggestions from people.

any way ,thanks
just tell me for depth please ?
you are blind or deaf , maybe ( i am not sure yet )
i say you leave LRLs' matter you ask me send pages from a book, but never i request this to you , you mistake me another people here
you ignore that and continue ignore all. you are the blank dead wall for all suggestions from people, i dont understand your mean.
cheers
