Hi I have a schematic for XR71 but is the same with Delta Pulse with litle differences. Gemini who built both detectors can tell us if it is the same so to give the schematic to forum without 50$.
The XR71 shematic in pdf file is existence in internet and it have some errors and donot work well,but i have the original XR71 files in protel99SE and it works very well.It can detects a cola at 1.25m stable and maximum deapth is 5meters for large object with 1mx1m coil loop.
The difference between delta pulse and xr71 is the operating frequency and the type of one transistor. The unregister fried why dont tell us the errors in pdf file? In this forum we share everythink who we Know. If anyone wanted money then what to say Carl, Reg, KT315 or the guru Erric Foster.
I am in agreement with you, I don't care of sharing the little that I know with the personnel of the forum, because no I win anything with that, I could buy the best detector of the market but I don't want, because my largest pleasure is to try to build one.
He/she excuses for my bad English...
