Description
Hyper Ping is a setting only available on
Traditional internal and Legacy sonar modules, for
use in shallow waters (depth range set to 6 meters
(20 feet) or less. In depths of over 6 meters (20
feet) the ping rate will revert to normal until depth
conditions are met.
When set to Hyper the display will provide an
accurate, undistorted image of the bottom at
speeds of up to 40 kts.
Provides a speed limiter; it is useful to adjust
the ping rate limit to suit local conditions. For
example, the ping rate may be too fast when there
is a hard bottom in shallow water.
Note: Ping Rate Limit is disabled if Ping Rate
is set to Hyper.
The sonar ping can be disabled. This is useful
when other equipment is being tested, or if
someone is diving beneath the boat. This setting
reverts to Enabled when the sonar module is
powered off.
Enables non-CHIRP channel frequencies to be
manually tuned.
Removes spikes caused by other
fishfinder-equipped vessels.
Note: Interference Rejection is disabled if
Ping Rate is set to Hyper.
Adjusts the ping rate in small increments,
according to the 2nd echo level. This results in
better sensitivity of the image.
Note: 2nd Echo IR is disabled if Ping Rate is
set to Hyper.
Restore all settings on the sonar module to factory
default. When performing a sonar Reset, it is
normal to briefly lose connection with the sonar
module.
Transducer selection is not affected by the Sonar
Reset operation.
Resets the Trip Counter of the sonar module
