I ve been detecting with my equanox 600 for 14 months .One of my favorite sites is an army training camp which i detected many times .I recently decided to buy the 6 inch coil as i read its better for areas with lots of scrub,tree branches etc .On my last hunt i went over an area i detected a few times before but this time i was able to go under branches etc more easily with the 6 inch coil .After digging out the usual bullets and casings i had a strong signal and 6 inch down up came a gold gilt peace medal circa 1945 .Needless to say I was thrilled as this was my best find to date .
