after scaning all night with the GT i disided to bring out the gold bug , Part of me was thinking na it will not pull any silver but i just wanted to use it anyway and i was going over the same spot i scaned with the GT and low and behold i got a 70 and i thought great the 1st non iron target tonight , well down about 6" and that was a good signal out came the 1st lead slug from this feild i was suprized the GT missed this as the feild is not trashy at all but i went right over this with the 15" WOT coil the gold bug really barked on it and some iron as well , not that i dont like the GT but i like the GB its fun to use .
