hello scs,

have seen that you have boar layout from relic hawk for sprint layout
would you please kindly share the (maybe upload as zip file)

many thanks

I think showed you enough how to make a good detector. I'm to here.

Ich denke, dass sie genug wie man einen guten Detektor zeigten machen. Ich bin bis hier.Fiele gruse!

This schematic is NOT for beginners!Work perfect with coil with good compensation receiver signal.

Hi to all which make this project,
I make Bulgarian version 'Coinseeker 2' 3-4 times and Musketar which is like Minelab RH....
SCS what means good compensation of receiver signal? What type of coil and preamplifier you use? Are you use standart DD coil and standart generator

[scs]

This detector is mod in RH-more sensitive in small pieces of metal.This detector work with receiver and transmitter coil in resonance.When the coil is made to seek a minimum receiver Signal no with elements C1,R1,R6 and C7.Fix coils with epoxy resin .With C1,R1-phase and R6 C7-amplitude make the received signal minimal.Is no problem use standard DD coil and standard generator.

You speak for C3 R4 and C4 R5?
What about the coil? if you use standatr dd27 Tx must to be about 48 turns/ 0.50-0,60 for 1mH and Rx must to be 180 turns/ 0.20-0.30 for 16mH. Capacitor of Rx must to be about 68nF what you make. Which type of shield you use

[scs]

DD coil 27 cm. diameter.R coil=T coil =120 turn 0.3mm.Frequency is not critical -5-12 khz.R coil and T coil must be in resonance by C 5 .Shield-aluminum foil or graphite.C3/R9-fase shift.

this is original Minelab coil I thing tx 1mH aluminium wire, rx 16mH Cu
What results you make with rx=tx = 8.2mH

[scs]

This is SIMILAR in Minelab detector,NOT COPY.Read more for coils and resonance.

5khz oscillator

[scs]

5khz oscillator-program oscilloscope.

20 ma? The Minelab oscillator only draws 10 - 11 ma and can be put into class C for 4 ma draw.
The IDX oscillator will run at 6 khz and draw significantly less too...

[scs]

20ма-yes,but amplitude is 35 volts...

[scs]

Beachcomber detector oscillator is great low frequency oscillator schematic.Very power and work very stable.

You mean this one?
