The F 75 is said to run 2 separate circuits 1 - audio 1 - TID circuit.
Now i know we have heard and read , go by tone first and numbers second and this is true 99% of the time .
Many a time i have a jumpy number but good audio and make a nice find.
Only on a very few targets has the reverse happened with bad audio but a solid number
Hunting in the winter a few years back with a friend, i passed a target that was real scratchy to hear but had a stable TID . I had my bud sweep it with his tone only
machine using a smaller DD coil than mine , said it was a no dig target.
I had to chip through the frozen ground to pop out a Indian head penny. Rescanning the hole showed plenty of iron at this old site , no surprise there
Not sure why the machine did what it did and have only seen this a few times.
Have you seen this happen to you . Thanks Mike .
