Oh and I find 2d very helpful early in the spring when I'm cruising back in the creeks looking for suspended crappie. 2d covers a wider area than DI and can be helpful when searching. I also use 2d when running from spot to spot. I've found lots of brush on the ends of points running 20+ mph with a well tuned 2d.

But yeah to get the most detail and see fish I use DI.
