Review of Mars Goliaf 15" coil for Whites

[j.l]

I received new Goliaf 15" coil today and decided to try it at a hunted out park where finding any good signals is difficult. I used the coil on a MXT, standard Relic Mode, disc set at 2, gain +2, locked ground balance at 80. I dug all good 2 way signals, I was surprised at the sensitivity for a large coil, several very small targets although junk were found at 7", I managed to find small charm about half the size of a dime at 4".
