[STC (Side Scan)],
[STC (Multi Sounder)]
STC reduces surface layer noise, to dis-
criminate surface fish from surface layer
noise. [0] is OFF and [10] reduces noise
approx. 5 m from the transducer. Too
high a setting may erase wanted fish
echoes.
[0] to [10]
[TX Pulse] The pulse length is automatically set ac-
cording to range. Use a short pulse for
better resolution and a long pulse when
detection range is important. To improve
resolution on the side scan display, etc.,
use [Short 1] or [Short 2].
• [Short 1] improves the detection reso-
lution, but the detection range is
shorter than with [Std] (pulse length is
1/4 of [Std]).
• [Short 2] raises the detection resolu-
tion, however detection range is
shorter (pulse length is about 1/2 of
[Std]) than [Std].
• [Std] is the standard pulse length, and
is suitable for general use.
• [Long] increases the detection range
but lowers the resolution (about 1/2
compared to the [Std] pulse length)
