Thanks! I am still learning to find gamefish on the SI/DI. This helps a lot.

Downscan / Sidecan frequency is high enough to pick out very small targets, that's why the ball of baitfish shows up as individual targets on downscan/sidescan.

Also with downscan you might miss gamefish feeding on baitfish but with 2D you'll see the blob and then some bigger arches around the blob those are gamefish.
