Coil for White`s classic

[Gervm]

If you are building White`s classic remember 4B or OMEGA coil. It works with classic very good and it is easy to make and tune it.

Also it work perfect with DD.
I made a 28cm DD coil and was very good!!!

[Gervm]

Yes, but Omega shows center of target better that more important for little coins etc.

Hello, gervm
First, thanks for your input
could explain how you make the coils, shield, and as the ring and results.
like everyone else does, or use different things, I am interested in your method because I see you have lots of experience.
Thank you and sorry for the language.

Hello, my name is Nocly and I want to thank for Carl to allow me to enter the forum, them comment that I am a pensioner who for reasons of health I must walk 3 hours per day, and found in this hobby the ideal form to walk and to entertain themselves, so in principle it arms a PI to me, design of the Gary friend to who shipment enormous gratefulness and special greeting, with I did my first (arms) finding many currencies but also much sweepings, so after months I decided to buy an equipment that discriminated, and acquired a B.H. to traker 4, with traker the things improved, but as I have some knowledge of electronics I abrí, it to try to improve it, but I was with technology SMD. I began my search in the Web. and it arrives at this forum, far but complete, even so I did not find anything my to traker. But a day being in the beach I was with another one " colleague who tapeworm an old White Classic 1 that did not work to him well and wanted to sell it, and as she saw that traker new era, enthusiasm and changes, other this to say it that I left winning, to it disarmament she repairs, it and now this turned into a 3 Classic .pero I go by but, and I would want to make a coil DD, or Omega, but my knowledge do not give for as much. In coils of the forum I found the contribution of Gervm, but due to the translation since I speak the Spanish, they are not clear to me the data, where it says DD 28 cm. To that it talks about, to the diameter of a coil, or to the diameter of the two superposed Where it says to 70 returns with wire 0,45mm and 220 do not say that, and either the diameter, later in TX does not say to 250 returns with wire 0.18 mm and 33nf but does not say the diameter, I understand if that talks about the Omega. If somebody can clarify this to me, very would be thanked for. Of my part if somebody wants the modifications that I did in my detector I raise, them the forum. Thanks and greetings.
