Red signals are much larger fish, or fish that are in the center of the
sonar cone, almost directly below the transducer. They return the
strongest echoes.
Signals that are yellow and some other color result from mid-sized fish
that are in a transition zone between the center and outer edges of the
sonar cone. They represent medium-strong echoes.
As a fish moves through part of the signal cone, the signal may change
from black to blue to green or yellow then back again. The signals may
appear to move up slightly and then back down, even if the fish doesn't
actually change depth. This is caused by the relative distance from the
transducer to the fish as it passes by the transducer.
Signal band thickness
Simply put, smaller fish return smaller echoes that result in thinner
and fainter signal bands. A thin signal can also indicate a fish located
toward the outer edge of the signal cone. As fish size increases, the ech-
oes grow stronger and the signal band grows wider. Signal width also
increases as a fish approaches the center of the sonar cone.
Ice Flasher Options
Split Zoom Display Mode
When ice fishing season arrives, you're often searching for fish that are
hugging the warmer water at the bottom of the lake. When walleye or
perch are holding right on the bottom, your M68C IceMachine can sepa-
rate those fish from the bottom with a remarkable Split Zoom display
mode.
In this mode, the right half of the flasher screen operates normally with
the surface at the 12 o'clock position and the bottom of the depth range
at the 6 o'clock position. The left half of the flasher zooms in on the six
feet just above the bottom, with the bottom at the 6 o'clock position and
6 feet
above the bottom at the 12 o'clock position.
