OK so I think that I might have a problem with my 1199 (w/7.65 firmware).
When i switch frequency's from 455 to 800khz, my screen (right SI) goes way out of wack, like when you crank the sharpness all the way up. 455 khz everything looks good, switch to 800, and cant distinguish a thing.
I just noticed this this weekend.
My settings
Lake depth ~ 15-feet
Boat speed = 3-5 mph
Chart speed = 4
Sensitivity = 12
Contrast = 12
Sharpness = off
SI Range = 65-ft
Color = Amber-1
Is this a TD issue or is my 1199 on the fritz.
I will try to go out this afternoon and grab a few screen shots.....didnt have my phone or extra SD card with me yesterday.
Thanks for your responses
