This is similar to how I use SI while spider riggin...

I'm inspecting details with the 800kHz while I spider rig from waypoint to waypoint...(and my waypoints are close together)...

I only use 455kHz when I'm in unfamiliar water looking for new structure all the way to the edges of the screen...

Then I drop waypoints on those new structure marks...re-position the boat closer...and scan the new structure with the 800kHz so I can see the details of the new structure...
