Wesmar SS395 Installation & Operation Manual page 10

When operating in split screen, SONAR settings
are used when scanning horizontal. When the
transducer moves to profile the PROFILER set-
tings will be used.
RANGE
When profiling the bottom select a range equal to
twice the depth. This will give full bottom coverage
across the screen.
PULSE
A long transmit pulse, 100% will deliver more
power into the water then a short pulse. A short
pulse has superior range resolution then a long
pulse. When profiling for fish just off the bottom
a short pulse should be selected. As the pulse
length is shortened, near and far gains will need
to be increased.
SECTOR
Profile has its own sector sizes with the center mark
straight down.
TVG
Time Variable Gain offsets propagation losses
as sound energy moves through the water. These
losses are compensated by the TVG setting. Losses
are different with different frequencies.
Adjustment:
160kHz set TVG to 300, span 200 to 600
110kHz set TVG to 500, span 400 to 800
60kHz set TVG to 700, span 600 to 1000
SPEED
Speed will change the scanning rate of the trans-
ducer as it sweeps over the bottom. For good bot-
tom detail use speed 1.
ENHANCE
Enhance is one of three filters. Enhance will help
in target detection of fish and objects on the bottom
small in size.
FILTER
Filter is the second of three filters. Filter is used to
reduce clutter; however, too much filter will lower
