After wondering why so many people have stability problems with the F75 i made the www.fisherf75.com page with tips and tricks.
Last week i a got a call from Ralph at Sun Ray Electronics, who brought other good information to my attention about the F75 and chattering.
I have to say that i never used notch on the F75 before (just disc) but after playing with notch and disc i was able to reproduce what Ralph talked about.
Here is some examples what can happen if you use notch and disc:
1. If you set DISC to 0 and use Notch to cancel out target group 1 to 7 you still have accepted 0 and that causes the detector to be unstable.
2. If you have DISC set anywhere from 1 to 7 and up and you go to notch and select any number from 1 to 7 you have NOT notched out the numbers, you have notched them back in (accepted them), because Notch does the opposite from the current disc setting. That will cause the detector to be unstable again, because accepted numbers from 0 to 5 run a higher preamp gain.
3. If you think you have messed up your Disc/Notch settings do a factory reset by turning the detector off and then push the trigger forward and press menu button while turning the detector back on.
I hope that will help some guys not to have to send the detector in for repair for something that is not broken.
Thanks Ralph for the input,
Andy,NM
