I just picked up a NOS 5.75" coil for the Golden uMax and I am impressed. What a Hot little coil as it will hit silver dimes at 8" with a perfect soft modulated High tone. The Golden is picky with coils as many don't match up with it but the 5.75" does nicely. Took it out yesterday and dug a Wheatie at about 7.5" easy with a perfect soft modulated High tone. I could run Sens. wide open without any chatter at all. These are great little coils for sure.
