	If I understand correctly, you are asking which program is best?? Eugene tried a bunch last summer, so he can advise you. I settled on "Pad2pad,"  but I have not made any pcboards, with it, yet. Pad2pad is nice and simple, if you try it, you may like it. It is free. goldigger

Hello Everyone . I have been working with sprint layout and it takes too long , or maybe I am too slow . I would try Pad2Pad as Goldigger suggested !!!
I tried to correct a tiny little mistake last night , I had problems Editing with sprint lay-out 5.0 !! You can see the trace connection on the photo that must be removed !! Forum member "Electrosoft" notified me of the Delta [single-board version] error yesterday, Thank-you .

Update: The Delta-Pulse sprint lay-out [single-sided circuit board] file error has been corrected and was re-inserted back into the Delta/Sniffer zip project package FINAL !!

	Hello Genius i am using now the famous russian transistors KT315(npn) and KT361(pnp) good result i have a problem in manual mode it is hard to adjust the threshold ,can change  :-the diode STTH1210D to another? Hello Genius i am using now the famous russian transistors KT315(npn) and KT361(pnp) good result i have a problem in manual mode it is hard to adjust the threshold , we can change  the diode STTH1210D to another?

Hello raya . I am not the Genius on the Forum . When you are first testing the Delta Pulse you can take the STTH1220D out of the circuit . Use a smaller search coil to start , 11 inch diameter is just fine . KT type transistors are fine . DO NOT USE CHEAP DISC CAPACITORS , they have 20% tolerance and will drift and cause circuit instability !! Your number 1 choice of capacitor should be "Polyester Metallized Film" then second choice should be "Mylar" !! Your resisistors should be 1% tolerance unless otherwise stated . Try my suggestions first and always double check the schematic in relation to the pcb board component placement . The Delta Pulse is the best all around choice for anyone wanting to build their first PI Metal Detector project !! Keep us posted on your results .
HH.........Eugene

	Hello,i am new to the site and sorry but i am litlle comfuse for this project.... Exist a complete pack (pcb.shematics.parts list.comments) to download? The part list is the same for 1 or 2 side pcb ??

When you get your 15 posts and become a full member, the downloads section will be open to you. Until then, read and learn about the items you want to use and build.

Welcome to the forums from Australia!

	ok thanks..

You're very welcome. I suggest that you go to the New User Introduction section and introduce yourself. Describe what kind of hunting you like and what detectors you use. You'll be surprised by the number of people who are interested in hearing about your and your interests. That's what makes the forum here so interesting and valuable.

Now go on. Get over there and introduce yourself. There are hundreds of people here waiting.
