Hi all
i would like to know what is the deepest MD that we can build it , for example, is here any Md that can detect 0.5*0.5 target about 3-4 meter underground?!
if yes, please upload the schematic but if no, so what is deepest Md that its schematic is exist.

best regards
mehdi

oh, not any reply?!!!

I think this has been asked and answered in the past. PI tends to have the best raw depth. Which PI design is the best? Don't know, but most of them can be tweaked to go deep with a large enough coil.

Reply to your question isn’t easy !!! , there is some parameters which reduced detector detection
Under soil. But my suggestion is PI with large square coil 1X1 meter but 2x2 meter is better.
About deeper PI detectors, superscan by Eric foster, delta pulse and sniffer XR71 seem together. But there are other good and versatile PI detector is hammerhead by Carl, you canFined detector all data easily here. if you like more complex detector ,
miner3 with microcontroller facilities .

Other thing I remember now , aban said about his PI detector with name siemens (It is with microcontroller ) .

He said deep is 10 meter!!!! . I remember he decided exchange siemens detector circuit
With other deepest detector . Ask from him, maybe help you. Also I think aban was the first
Guy , bring all data about sniffer xr71 to this forum .

Hi carl
thanks, but which pi?my clon avr cant detect more than 1.3 meter , my surf pi with improvement to go deeper with 0.5 meter coil cant detect more than 1.6 meter, my delta pulse with 1 meter coil only can detect at 2.1 meter ( target is 0.5 meter iron sheet and test is in air at all test)
btw, thank you very much for your reply

Hi dear aft
do you have the superscan schematic and other information about it?

all the best

aft,
please sent abans eamail to me with PM or to my email [email protected]

Mehdi , please search superscan pi , you can find thread by rospy.

thanks a lot aft, but i can not see any schematic there!!

you have DP... increase strobe impulse to 1000 us. decrease pps to 25 hz or low. change mos-fet on more powerfull one. change battery on more effective one. use 1 meter ramka coil and more. try... you have all for the success...

HI

THANKS FOR YOUR REPONSE.

CAN YOU SEND ME THE REFERENCE OF MOSFET more powerfull

THANK YOU

0.5 * 0.5?
Is this Millimeters, Centimeters, Inches or Feet?

Anything LESS that FEET at 3 to 4 Meters Deep, and your DREAMING.
