i used mylar cap for 1.5 nf c4,c5.,c6 . cheramic plate cap for C17 47pF and c13 15pf.

All other caps is poly ,,for me Wima 100nf MKS2 caps worked good here

new battery and gave it 12v today,,tested and play with it this eavning,,yes its stabil and sensitive

now we actually tested the dp capability and circuit stability, we have to modify the dp for more powerful dp. i made some modification on my dp it will be soon posted here all schematics for all us to study and to build a very powerful dp to be posted here. i owe all this from eugene52 and ideas of elbombaci,carl nc,goldigger 1950,cornelius they are the wiz of this projects.

have you tested your DP with 1*1 coil ?
it can detect big target .......4m or more ?
sorry for my bad englich and thanks

Test with detectorpro`s pulsecoil on deltapulse

Yes this coil is well fitted for deltapulse..
i am in shock over its performance,,can it be better Huh??

1m on a 33cl alu beer can

big coin 45 cm
and if i move any big iron obj in livingroom ,,exempel  grind to my fireplace (1m x  40cm) it is ca 3m.away .deltapulse start humming
man i love this detector

yes my 1x1 mtr square coil is tested in my targets. and it depends the size of the target. eg.alu beer can at 10ft(impossible) 50cmx50cmx50mm at 12ft (easily detected. it deflects half of the meter reading) note:ground buried metal objects.

coil:1x1mtr=8turns awg #24=not so sensitive
coil:1x1mtr=16 turns awg #24= very good result
coil:40cm=23turns awg #24=standard and yielded very good result.

you can try detecting larger metal eg 5ftx5ftx50mm metal buried underground at 20ft using 1x1mtr coil. delta pulse is deeper. using on small targets eg.gold nuggets it requires modification (smaller coil,frequency,sensitivity,faster pps and pwm)

to those who sucessfully made their Delta pulse, i just want to ask what what is your normal output voltage at TR6 and TR7 measured from ground, i cant tune my delta pulse, it is always beeping, even if i press reset button sound will fall a few seconds then beep again continously.  I used the single side pcb layout and my coil is 23turns, #24, 40cm diameter.
