Output
(1) Pulse(High)(Low)
Pulse(High):
Selects the high frequency “transmit ON time” pulse length.
Pulse(Low):
Selects the low frequency “transmit ON time” pulse length.
By changing the transmission pulse length, the Sounder effectively changes its detectable depth
and image resolution.
Setting range:
1 (ultra narrow), 2 (narrow), 3 (medium), 4 (long).
1 (ultra narrow):
High resolution of fish schools but detectable depth is very shallow.
2 (narrow):
Good resolution of fish schools but detectable depth is relatively shallow.
3 (medium):
A good balance between detection resolution and detectable depth.
4 (long):
Deep detection ability but fish school resolution is not so good.
