so thus far, everyone seems to like DI on the bow and don't really use it much at the helm,
I was envisioning SI to find brush and DI to get a good look at it, see if it's worth fishing.
This is indeed, effectively using each sonar tool (2d/SI/DI/GPS) for what each is "best at"...
SI advantage is "findin stuff"..
DI advantage is "pickin it apart"...
2d advantage is "sittin on top of it"...
GPS advantage is "guidance to it"...
