Regards to all
I made TGSL a year ago with the DD probe 26 cm (

) and doing well. 1E = 25 cm in the air.
I would like to do more of this detector DD probe 38cm or similar size but I have no data to.
I wonder how much of the thread that the thickness of the wire, which inductance and the resistance of Rx and Tx.
Sorry for bad english
Thank you in advance for your answers.

  You want the same inductance, Wire size and Resistance of the first coil.   Your just going to use less wingdings for the large coil.   Use a coil calculator to see how many winding your  looking for.

Thanks for your reply
I tried a couple of calculators or even one not working properly and I get different results or not getting.

Posted on: April 29, 2016, 07:19:14 am
I've made a dd probe (38cm).
The data are as follows:
TX 34 laps 0.50mm wire 1,067yH 3.4 ohm
RX128 circle 0.25mm wire 14,878yH 40.9 ohm
Coil nulled perfectly !!
The detector works well but we have to increase the depth of 38-30cm for 1 euro.  Cry
I am very disappointed and I'm sorry because I lost time and I got the result.
How can we increase the depth of the detector. There are many modifications that are not too helpful percent detector without them working just fine, but no one has tried to increase the depth of detection, which is a weak point of the detector.
If someone has an idea how to make a mod to increase the depth of some of the shows since I have plenty of free time for experiments.
ocemo I get depth if we do a mod oscillator and how to modify it.?
Thanks for your answers
