Need Humminbird training recommendation

[Tazmnaz]

Just purchased a NOS Humminbird 777c2. Wish I could have afforded the new 3D imaging, but c'est la vie.
I am wondering if there is a recommended website or link to video interpretation, set up, etc. that will teach me how to get the most out my unit.
I remember reading somewhere a while back about someone who did a video that showed the sounder returns along side an Aquaview cam video to actually see what was on the 777 screen in real view but cannot find where I read that.
Any links or help would be appreciated. Since there is still ice out here, I have some time to get some knowledge before I hit the water.

Thanks

--Change User Mode to Advanced
Menu, Menu, right over to Setup, down to User Mode, change to Advanced. Exit out.
--Beam Select. 200 & 83. It's under the Sonar tab.
--Set the sensitivity on each beam. Under the Sonar tab. Set to max then back off as necessary.
--Set the Real Time Sonar Window to WIDE. Sonar tab. Pay attention to this column when fishing. It's educational.
--Turn Fish ID ON. Under the Sonar tab.
--Fish ID sensitivity. Adjust when fishing to match conditions of water. Too high gives false reading. Watch the RTS signal. If you have marks showing in the water column and the Fish ID is absent, it is too low.
--Turn Depth lines ON.
Menu, Menu, down to Depth lines, change to ON if it is OFF. Exit out
--Set manual depth. This depends upon where you fish, how deep it is, and time of year. Ordinarily you have some idea of the depth you will find the fish. The idea is to set the upper limit and lower limit so that the depth line divisions are convenient. 0-40 makes depth lines at 10,20 & 30. 30-110 makes depth lines at 50,70 & 90. I find this very useful.
--Bottom View. I like Structure ID. Whatever you prefer.
--Surface Clutter. Set on the water according to conditions at the time. Use it like the Noise Filter. Less is better as long as you don't have too much mess on the screen. When it gets too messy, use these and Sensitivity to clean it up.

Experiment all you want. If you get worried you messed it up. Go to SETUP and RESTORE DEFAULTS and it will set them all back to factory specs.

If you fish water deeper than 60 feet you MAY get better performance setting the frequency to 200 only. It seems to improve the ping speed.
