have not tested it with another coil and there had not had time to do another. I also work with the coil Minelab Musketeer, but you have to change the values of the capacitors of TX-RX, 220nF and 68nF for, according to the scheme presented Ivconic.

I make this coil with balsa wood, with the data mentioned verotopasera for the SMW.
Fine tuning is done with the loop seen in the photo.
Data DD coils 27-28:
TX - 75 coils, wire of 0.45 mm, 200 mm in diameter.
RX - 160 coils, wire of 0.27 mm, 200 mm in diameter.

I made the top panel and use hand-made antenna in addition to changing the values of capacitors other change needed is a

Hello Verotopasera
TX home made for my coil = 220 nf
RX = 68 nf

how to add LED "LOW BAT''indicator for low battery voltage

here what it serves and where it connects

and where it connects

Look on Fisher 1265/66 schematic.
It is a switch for maximum sensitivity as i recall.
I took the whole stage from Fisher 1265/66 , at the time i did that version.

Hello everyone

I just finished this detector works from the last weld. I have a serious problem. I detect a € 2 coin to a maximum of 10 cm and a metallic plate of 10 x 10 to 20 cm and bigger problem, if I just touch the potentiometer R 16 or 3 thread of connection (GEB), I have a strong signal in the speaker as if an object is detected. Where is the problem?

Greetings

Hi Freddy67
a percentage of a large mistake in the coil.
Coil is 28cm DD,
TX= 65-75 windings, 0.45mm wire,
RX= 160-175 windings, 0.22-0.27mm wire...
best time
