I think of my different settings as tools...just like a set of screwdrivers..(every screwdriver fits a different screw for a different task).....each of the different SI settings works well for certain things I want my unit to show me...and not so well for other things I want my unit to show me....

Frequency...I like the 800kHz for the clearer images...unless I want to see fish that are closer to the surface out to the sides and above the upper reach of the 800kHz 130° beam...then I use the 455kHz.

I like a medium Contrast (10-12) ....unless I'm using a different pallette than blue that needs a different Contrast setting...

I like "Sharpness" off...unless I want the fish to "pop out" on the screen....then I may raise the "Sharpness" accordingly...

I like a shorter "SI Range" (65-70ft left and right") to make structure look bigger...unless I'm looking for stakebeds in new water (I may set it out to 90-100ft just to cover more water)...

I like "SI Side" to "Both" (left and right)..unless I want to artificially make structure look bigger on the screen..(setting the SI Side to 1 side only...left or right... , in effect, "Zooms" that side's image)....

I use DI only for...well basically nothing... (because IMO the DI in the HB SI stinks)....I have all my DI views hidden...

I constantly change "SI Sensitivity" (in my "SI Enhance" popup menu)..this brightens and darkens the SI image as the image changes due to water depth, bottom composition, waterborne particles, etc......"SI Sensitivity" is my most frequently changed setting...
