That's actually a good comparison shot from the DI image of the same structure ...

Some suggestions ... :

*Lower Range in manual is good ... But set it closer to 2-3ft below actual water depth ... This will make less displayed bottom on the display ...and structure in the water column will display bigger ...(this works in the DI image also) ...

*Crank the Chart Speed up in 2d ... (This is a global setting which will have to be slowed back down for DI/SI) ...

*Switchfire Clear mode and raise Sensitivity until there is just a little clutter on the screen ...

And try the other palette choices to see if one of the others looks better to your eyes ...

Another trick that's a little less handy is to set the "Transducer Select" menu to "Dual Beam" to get the maximum amount of ping dedication to the 2d transmitter ...
