OPERATIONAL QUESTIONS & ANSWERS
Where Should The Gain Control Be Set?
For ice fishing - the gain control should be set so the bait you are
fishing with is shown in green color on the dial. This color should be
set while the lure or bait is at the normal fishing depth. As the bait is
raised toward the surface the colors will turn to orange and possibly
red, just below the surface. This happens because as the bait is raised
towards the surface the signal strength from the bait gets stronger,
resulting in color change.
For open water fishing - set the gain control so as to get a strong
bottom echo along with a second echo. You may need to switch to a
deeper range to see the second echo. The leading edge of the bottom
echo will show a solid Red band, then bleeding into the orange color,
then the trailing edge of the bottom will bleed from orange into the
green color. Good bottom echoes, most of the time, will show all three
colors, starting with Red, Orange, into Green.
Why Can't I See My Bait While Ice Fishing, or like I
can while ice fishing?
For Ice Fishing - In order to see your bait it must be in the center
of the cone and you must have your gain turned up high enough to
see it.
For open water, with the position of the transducer mounted to
the boat, it is hard to get your bait there, and with the motion of the
water it makes it difficult to keep it there. If all conditions are right
you will be able to see your bait.
