Here are my settings and some more information I found on the SwitchFire modes.

My HB 777c2 Settings

Quick Menu or the first menu:

Sensitivity = 10 (so far this has been the best for me)
Chart Speed = 5 (I change this with the speed of the boat if trolling)


Sonar Menu:

Beam Select = 220kHz
Surface Clutter = 5
Switch Fire = Clear Mode (I have played with this some, I think there’s a rule of thumb this is for shallow water, I maybe wrong, I fish 25 ft or less most of the time )
Fish ID = Off
RTS Window = Narrow
Bottom View = Structure ID
Zoom Width = Wide
83kHz Sensitivity = 0
Noise Filter = High 3

Hope this helps. If ya'll find out I'm doing this wrong let me know. Like I said I just play with it till I get it like I like it, don't know for sure it's right or wrong :D
