Thanks Morgan,
I will have a go at building this and let you know how I get on. |

Hi Morgan.
LOng time that i don´t speak to you, but on this time of the year, i had lots of things to do. So my time to experiment, has limeted to a few minutes or hours. I hope after i finish some work, i will be back 100% to conclude my pdk. About zahori antenna, you said that the external loop is not needed. So can you please let us know if the center antenna, plus the ring that i also have set up like the one on the picture you post, have the same dimensions? What did you gain with this mod? My mini zahori, have both antennas and the ring at the center. My expiencies are minimal with it. I had detected a saml aluminium foil about 1 meter distance. Also i got power lines from about a mile on the country side. Regards Nelson Quote:

Try the LRL near your TV,if without the Big antenna become more sensitive to TV screen radiation use with the small and SAMPLE only,if not,let stay like this. In my Mini Zahori it works 3 X more sensitive without the big antenna. |

very easy to build,i buy one nice and cheap wood box(in the chinese shopp) and cuted two discs in wood,inside is the antenna. The handle is in aluminium.Just take a few hours to build. |

Morgan the larger outside coil is still connected to ground or is it open?

As i told,after disconnect the large coil i get 3 times more power in the MINI ZAHORI(locating my TV screen),but maybe lose the LRL efect in the fields,i need to make more tests... The Zahori is the best LRL for the beginers,but i have the PDK´s for my TH,i´m not a beginner ;-) |

If I get any real indication I will improve on it, that's for sure.

i think Nelson build his LRL better than mine,becouse most of the times i can hear the radio with my Zahori,dont know why... |

Well,this happens when i disconnect the big loop,yes now its open.

hi morgan
I want to combine them bfo with Mini Zahori .Please help me to make this plan.How to incorporate it into what is antenna type, it will be like?Whether its sensitivity to small metals goes up? waiting for you |

Starting Box
Well I'm cutting out a 8x5x1 wooden box with my laser and will start on the circuit monday. It's the weekend here so it will have to wait. Morgan The BFO is like some vlf detector LRL I'm guessing. The BFO is set near or at the gold frequency and also is setup to detect the changes in the effect. Any way I'll test the unit and keep updates here.

40W. I use it for many different things. It's very easy to use. I draw out the design in auto-cad and the laser program cut to scale.

2 passes @ 20% power. About 20 seconds. That's the sides of the box that I will glue together to make the 8x5 frame.

40W laser is not a good thing to mess with
think about reflections it could have , can hurt... your eyes and make you blind if you don't use special glasses, forget about if you're not trained to use them at such (or bigger that that) power just my 50 cents regards Max

Morgan, Thanks for picture of your mini Zahori just a couple of questions. Could you show a picture of the front? I don’t quite understand why you need the front wooden disc covering the antenna, as I thought that the timber would dull the signal strength as this is a directional antenna? Also using metal bolts & nut would this have any affect on signal strength? I hope that this doesn’t sound too stupid but I just want to understand. Thanks |

Hi to all friends that make mini zahori...
did you really can detect buried gold by this device ? How can we calibrate mini zahori for detecting only gold or only silver ? Thanks...
