I just purchased a clearanced BH 3300 from Radio Shack on Sunday, June 18, 2006 for $111.97. I have never used a metal detector before and by reading some input from this sight I figured this might not be a bad detector to get my feet wet.
I have a question about manual ground balancing in the pinpoint mode on the BH 3300. It says to find and area that does not have any metal and raise the coil into the air with the ground balance knob set on preset (fully counter clockwise) and the machine in the pinpoint mode and bring the coil back to the ground. When I do this I get a fairly loud humming sound within 1" of the ground. Then when I raise the coil back into the air and turn the preset knob clockwise 1/16 of a turn and return the coil towards the ground the humming noise seems to start when the coil is 1.5-2" off the ground than the previous setting and it seems to get louder and louder with each change in ground balance setting.
Also, I am having problems when scanning the ground in all metal mode, when I hear a high pitch tone that indicates an item towards the $1 (right side of the scale) and I rescan the area where I received the first sounding, I can not find the place that emits the same tone in a lot of instances.
Any suggestion greatly welcomed.
