DID SOME TESTING ON 2D DI SI TODAY

SORRY NO PIC, I USE 3 TENNIS BALLS TIED TO BOUY IN 17 FOW,ONE AT 1 FT,ONE AT 2FT AND 3FT,TO SEE THE BOTTOM BALL I HAD TO BE RIGHT OVER IT,2 BALL ABOUT 5 FT TO ONE SIDE AND THIRD BALL ABOUT 8 FEET,SO RAISE THIRD BALL TO 6 FT AND AT 17 FT IT WOULD START TO BLEND IN WITH BOTTOM ON ALL UNITS.I HAVE ONE DUCER THAT I CAN PULL TRIGGER AND IT WILL TILT SO ON SPOTLOCK I TILTED IT AND COULD SEE 6 FT BALL TO 17 FT ON DI AND 2D.I THEN SET DUCER AT NORMAL FLAT LIKE SUPPOSE TO BE AND TURN DUCER AND COULD SEE 6 FOOT BALL UP TO AGAIN 17 FT WITH DI AND 2D WOULD SHOW AT TIME,NOT PERFECT LEVEL.THE MAIN THING WAS WHEN I GO OVER BALLS THE SI SET AT 50 FT ON BOTH SIDES VS DI SET AT 30 FT THAT THE BALL WAS 3 TIMES BIGGER,I HAD 998 SET ON FULL SCREEN AND 859 SET ON FULL SCREEN AND A LOWRANCE 7 ELITE AT FT, ALSO I NOTICE THAT AT .7 TO 1.4 SPEED THAT THE BALLS WERE ROUND WHEREAS AT BELOW THAT IT WAS OBLONG AND FASTER THAN THAT IT GOT SMALLER, ALSO IT WAS A SOFT BOTTOM.WANTED TO DO MORE TESTING BUT TOO HOT AND TROUBLE WITH BIG MOTOR,HOPE TO DO MORE BUT NEED TO WORK ON MOTOR

genec, what did you have your Chart speed set at?

ON SI,IT WAS ON 5,DON'T KNOW ON DI

genec, the chart speed is global, if you have it set to 5 it is the same for SI, DI. From my experience I know the higher the chart speed is above boat speed makes things look longer. You might try testing at a chart speed closer to boat speed. Maybe Greg (HB) will comment on this.

Nice report Genec, hope you get your big motor lined out. Rdjj is correct on the global chart speed, I think!

GUYS,DI IS A 859 UNIT,SI IS A 998 UNIT,JUST HAVE NOT LOOK YET TO SEE WHAT 859 DI WAS SET ON. ALSO ON THE FRONT UNIT I HAVE A LOWRANCE ELITE 7 THAT I CAN TURN IN A CIRCLE AND ALSO MAKE IT TILT SIDE WAYS

That changes the equation a lot genec. My brain did not catch that in the first post. Would be interested to see more testing.
