7. The display shows many black dots at high speeds and high
sensitivity settings.
What you are seeing on-screen is interference, normally caused by cavita-
tion, or air bubbles in the vicinity of the transducer. Often the propeller is
the cause, and adequate separation between the transducer and the
propeller is necessary.
8. The bottom reading disappears during a hard turn.
This is normal as the transducer comes out of the water, and will correct
itself when the turn is complete.
9. The screen begins to fade out. Images on the screen are not as sharp
and clear as normal.
Check your battery to see that it’s fully charged - the
100ID
will not operate on less
than 10 VDC.
