Yesterday I was detecting and my Fisher f75 suddenly(has happened twice before) went into overload mode. Other times it went away, but this time it hasn't stopped. I changed the batteries, unplugged the coil, reset it. Everything I know to try to fix the problem. Only when I set the sensitivity below 30 it stops. Obviously something is wrong, but I was just wondering if it was a bad coil or possibly internal? And wondering if this has happened to any other F75 users and if you were able to fix the problem on your own.
