How Multiple CHIRP sonar settings provide clarity
Multiple CHIRP ranges from a single transducer: Because Lowrance fishfinders give you the option of using more than one CHIRP Sonar signal, it’s important to understand which one is right for your fishing situation.
High CHIRP frequency selection: Most frequently used for freshwater as well as more shallow coastal areas. It provides the greatest detail for tracking smaller objects, like your lure, or identifying game fish from bait fish, as well as game fish that are near structure or on the bottom.
Medium CHIRP frequency selection: Wide coverage makes this frequency best for covering large areas while searching for structure or fish. However, this option is not as detailed as High CHIRP and will not penetrate as deep as Low CHIRP.
Low CHIRP frequency selection: Provides the greatest depth performance, while marking fish targets throughout the entire water column.

I believe you got that wrong my friend...
The lower the frequency the wider the coverage area with of course better depth penetration and like you said less clarity/resolution/target separation....but really it's good enough.
I think you better reconsider telling everyone that the low frequency is not needed or necessary...if you ever tried using it, you probably wouldn't say it's unnecessary.... Try it out, I think you'll like it.
