Yes, I had a short in my coil from the factory. Used it once never was right. Set it in the closet forgot about it. Well took it out today and set out to fix it. Well I did. Had a short in the plug. One of the solder points were touching the inside of the metal plug. I wrapped the joints with electrical tape and walla. Ground balances perfect, gets targets at 6 inches or more. I am happy. Headed out today for a park hunt. Gonna get it all on film. Episode 2, Diggin' the South. Check meout on YouTube. Zaxfire69 Diggin' the south
