Hey guys, I am far far from being in most of yall leagues. I am a dumb, but persistant, man who enjoys making things with my own hands.
I need some help. I have a 11" DD coil housing that I need to make a coil to go into.
Here are some of the things I know that yall need to know.....
1) I am building a HammerHead PI from Geotech
(In case yall need some specific info)
2) I will be using 26 AWG, Teflon coated, 600V, stranded wire
3) I am needing to know how many turns (winds) do I need?
I need to go as deep as possible and still detect smaller nuggets.

I know things like the coils Uh makes a difference, but I dont even know what that means. I do know (I think)that we need to have a high UH, right?

Thank you for your help !!! God Bless Smile Smile Smile
