I leave mine on 200/83 most of the time...

This will give you the widest range for picking up fish in the outer reaches of the 83kHz 60degree cone ..

And give the best detail of structure in the 200kHz 20degree cone...

Also to make the structure really "pop out" on the 2d sonar view... Set Switchfire to "Max mode" and then adjust sensitivity to a level that shows some surface clutter but not too high to cause extra clutter in the water column...( I generally run my sensitivity up until some widely scattered dots (clutter) start showing up in the water column)...
