Rickie is 100% correct I just couldn't find a screen shot where I was over BP for a longtime. GPS speed on my example was .2mph (chart speed 3), but I had slowly drifted over the BP. The 2D is history "right to left" so as Rickie stated it will fill the screen from the top of BP to the bottom depth if you can stay over it long enough.

justatrollin, I have a 958 DI on the bow with latest software (7.660) installed. It does not have a jigging mode like my 999 SI on the console. I assume because it was built as a DI model and does not need to prioritize SI. Rickie may know fore sure what the answer to that is.

If you have your RTS Window (Real Time Sonar) "ON" and set to "Narrow" you will know the instant you are at the BP (remember) everything left of the rightside is History. The RTS Window is like the old Flasher.
