I run the C/J mode at factory presets with the trigger in the center position. This little 4X6 seems to be one of a hundred. this little sucker is hotter than a firecracker and i have no complaints. It doesn't have the depth of my super 12,but is a killer on the tot lots. I don't bother getting close to the poles. I have a detecting partner who is handicapped and i let him hit around the poles. I deliberately pass over a lot of dime and quarter hits so he and his Ace 250 can find them.In time,,,I am going to follow Monte's suggestion and get the 5.3 coil and explore with it. I don't get to detect much because i am a health care provider and i am usually house bound. Winter is coming,time to save for new headphones,lower rods and another coil LOL.......Tom
