SWG 31 Copper Wire DD Coil

[paku]

ok , but i have Que to you:
can i use the TGSL coil(that you say in here)for Idx pro VDI ?????????????????
many thanks

TGSL coil And IDX coil Is Not Same You Will make Your TGSL coil Kong if U ar use to IDX

i get 6.58kh

hi
i want know , have differeny between 0.7mm and 0.5mm wire,for example i make 500mkh by them (0.7 and 0.5 wire ) , any one know?
regards

the difference is sensitive of signal to object

One would have lower DC resistance and thus higher "Q"

"Q" is reactance over DC resistance. A coil with the same inductance has the same reactance at a given frequency
so changing the resistance changes the "Q". Now generally a higher "Q" is desirable but in metal detecting we
want a lower "Q" for specific reasons. One is the transmitter will be less affected by loading to the ground. Another
is the receiver will be less "touchy".

Most MD manufactures use a smaller gauge wire for the receiver than the transmitter so the receiver is less touchy
and the transmitter uses less current...
