Jap thank you

I will compare my implementation, that of # 105 and # 107 and the sheme make the best until the Lmeter

I think it's pretty cool and stable.

My coil works better without foil. When I put tinfoil lose one two inches.

Hi bravodenisu
nice project,coil,,, its PI,NOT VLF?
Whats name?
best time

i dont have BC327 and 2N3906 PNP transistor. which type of resistor can i replace it?
best reguard.
MNW.

[Freddy67]

Hi
Any pnp transistor can operate. Search on Google.
3906 is not in the final scheme and it is not resistance but transistor. I think before making such an arrangement should at least know a little components.

Actually not. The best cheap choice for T1 and T3 is BC327 because of very low Rbb at about 30ohm. Fun part is that the so called "low noise" BJTs tend to have much larger Rbb and will not perform well here.

With BC327 you may expect noise down to 1nV/sqrt(Hz), which is not bad at all. It is the key feature of this rig, so cherish it

plz...... I want component side of this pcb.........give me........plz.......

Hi kkyawhtet

See # 438. It is in any case advisable to read the full article

Best time

Yeah! thanks U.. Freddy ..but I do not understand this article......... I wanna http://www.geotech1.com/forums/attac...1&d=1236545978 ( This photo of component side ) Plz........

Hi kkyawhtet

The right diagram is # 107 page 5. The detector is also called Cesar Caezar ... I attach the pcb Jpeg.

Errata and question

[salih]

hello 2 all
is the Detector can detect gold nuggets
I want reagent experience but do not have Tr:MPS13 and LF347 I hope you help me. what I do

[Geo]

There is no difference. The PCB can be powered both with 2x9V 18V or 12V with 8 AA batteries of 1.5 V. The coil is, I repeat to Teknetics T2, SEF Butterfly 12x10.No there's more.

Hi.
Who wire did you use for coil shielding???

Hi.

I have not done the coil SMW. I've used an original Teknetics T2 coil. SEF 12X10.
