Fish Detection Settings Menu - Raymarine LIGHTHOUSE 4 Operation Instructions Manual

Setting
[AHRS stabilization]
The AHRS built in to the RealVision™ 3D
transducer is used to stabilize the sonar
image onscreen based on your vessel's
detected movements.
[Reverse Port/Starboard]
When a RV100 transducer is hull/step
mounted the transducer can be installed
with the cable orientated towards either
the bow or the stern of the vessel. On
installations where the transducer cable is
orientated towards the stern of the vessel
then the [Reverse Port/Starboard] control
must be enabled.
[Interference rejection]
Removes interference caused by other
transducers on your vessel or from vessels
equipped with transducers close by.
[2nd echo rejection]
The control helps to remove false target
returns or false bottom that can be caused
by signal reflection.

Setting
[Dual-channel ping mode.]
On Axiom® Pro and Axiom® 2 Pro displays,
when using multiple transducers at the
same time you can balance the ping rate vs
interference between the two transducers
using the [Dual-channel ping mode.] option
By default Independent ping is selected, if
you experience interference then you can
'lock' the transducers to ping at the same
rate.
Locking to the transducer with the fastest
ping rate should give the best results.
[Reset sounder]
Resets the sonar module to factory default
settings.
[Reset trip]
In installations that include a speed
transducer connected via the sonar
module a trip log is automatically recorded.
Selecting this option resets the sonar
module's trip log.
