Hello BH, Been there done that many times, I did factory reset prob 5 times yesterday it never really helped. I want to love my new machine but at this point I think I would have been better off using the $900 to buy two or three used machines that would do cover every thing this machine is supposed to be able to do. I see all the positive comments on the internet about the 800 and I wonder if I am in the twilight zone LOL. Cause I have not seen what all the hype is about. It may be time for me to contact Minelab.
