I used it kind of before but not correctly and now that i know how to use it i should kick my self in arse for not learning it before.I checked almost all targets today and it was about 98 % correct didn't stay out long went to park but one thing for sure i pulled more nickels today than i have in a while.Before when i used it i just kind of re triggered over target after i pinpointed to see a few dc numbers it was OK but the way you are suppose to do it works well really helps. Thanks Gene and Larry
