your hand. While squeezing, if the zero gets smaller you need to
work on the transducer attachment. To solve the problem, especially
with a metal transducer arm, remove the transducer from the metal
arm. Then tape three layers of black electrical tape around the arm in
the flat section of the arm, then lay the transducer against the tape and
continue to tape it onto the flat section on the metal arm. The tape cre-
ates an insulation layer between the metal arm and the plastic hous-
ing of the transducer. This insulation layer eliminates any transmis-
sion vibrations caused when the unit transmits the signal to the water.
What Does the Bottom Light Mean?
Besides depth the bottom light can give you a lot of information.
The width and color content of the bottom signal can tell you what
type of bottom it is.
Ice fisherman can look for movement of color in the bottom sig-
nal. If you see a red line move through the orange or green part of the
bottom signal, it's probably a fish close to the bottom and away from
the center point.
Open water fisherman usually can't see this because the boat
moves too much. You can, however, see changes in the bottom type
as you move along. The more red in the signal, the harder the bottom.
The more green and orange in the softer the bottom
Why is the Bottom Indication so Wide?
While fishing in a depth of 30 feet, a normal width of a bottom
indication is from 5 to 12 feet wide. The width of the bottom is actu-
ally the summation of the radius of coverage on the bottom and is con-
trolled by the gain control. The bottom width and color adjust auto-
matically. The leading edge of the bottom light is the actual depth.
The color beyond is the area, within the cone of sound, that is around
the center point of the circle you are covering on the bottom.
