Chapter 6: Using the Fishfinder

DSM Setup

Certain conditions, such as a hard bottom or other vessels equipped with a fishfinder,
may affect the DSM. The following DSM Setup controls enable you to change settings
to allow for this. As they are held in the DSM, they are applied system-wide.
MENU ITEM
DSM Reset...
Restore all settings on the DSM to factory default. When per-
forming a DSM Reset, it is normal to briefly loose connection
with the DSM.
Trip Counter Reset...
Resets the Trip Counter of the DSM.
SONAR Interference Rejection
Removes spikes caused by other fishfinder-equipped vessels
2nd Echo Interference Rejection
Minutely adjusts the ping rate according to the 2nd echo level.
Results in better sensitivity of the image.
Ping Rate Limit (per sec.)
Provides a speed limiter; it is useful to adjust the ping rate to
suit local conditions. For example, the ping rate may be too fast
when there is a hard bottom in shallow water.
Ping enable
The sonar ping is normally enabled. It can be disabled. This is
useful when other equipment is being tested, or if someone is
diving beneath the boat.
Any changes that you make to the set up are saved when you power off the digital
sounder module (DSM) except for the following:
