Sonar operation | HOOK X series

Ping speed

Controls the rate the transducer uses to send so-

nar waves into the water. Ping speed adjustments

can help reduce interference from other trans-

ducers. When using shing modes, ping speed

settings are optimized for the selected shing

conditions, so in most cases, adjustments are not

necessary.

Sonar options

Noise rejection

Uses advanced signal processing to monitor the

eects noise (boat pumps, water conditions,

engine ignition systems, etc.) has on your display,

and then lters out undesired signals.
