19.15 Transducer settings menu
Setting Options
[Transducer]
Allows selection of Sonar transducer.
List of available transducers.
[Display depth as]
Determines the position from where depth
readings are taken from.
• Below keel
• Below waterline
• Below transducer
[Speed transducer]
Allows selection of Speed transducer.
List of available transducers.
[Calibrate speed]
Allows you to enter an offset between actual
measured speed and the current speed
displayed by your transducer.
Offset value.
[Enable temperature sensor]
Enables and disables the selected
transducer’s temperature sensor.
• On
• Off
[Calibrate temp]
Allows you to enter an offset between
actual measured water temperature and
the current temperature displayed by your
transducer.
Offset value.
19.16 Sounder settings menu
Setting Options
[Sounder name]
Allows you to rename your sonar module.
Onscreen keyboard.
[Ping enable]
Enables and disables transducer ping.
• On
• Off
Setting Options
[Ping rate limit]
Allows you to restrict the transducer’s
maximum ping rate to suit current
conditions.
• 1 to 100
[Power mode]
Adjusts the transducer’s signal strength. In
[Auto] the sonar module will automatically
determine the optimal power based on
current depth, speed and bottom signal. In
[Manual] you can adjust the power to the
desired level.
• 1 to 100
[Ping rate]
Hyper ping should be used at speeds of up
to 40 knots in shallower waters (6 metres
or less). When the depth reaches 6 metres
or above the ping rate will automatically
reduce to normal until depth conditions are
met.
• Normal
• Hyper
[Dual channel ping mode]
On sonar modules that offer simultaneous
dual channel operation, such as the CP570,
The ping mode can be changed.
[Auto] the Fishfinder app will select the best
mode chosen based on range settings.
[Independent pings] maximizes ping rate
but may introduce interference.
[Simultaneous pings] reduced ping rate and
reduces chance of interference.
• Auto
• Independent pings
• Simultaneous pings
[Tune frequency]
Enables manual tuning of non-CHIRP single
frequency sonar channels.
The adjustment range is determined by the
transducer/sonar module.
• Supported frequencies
