2.3.1 Adjusting the Frequency of the Transducer
Different sonar frequencies reveal different levels of detail.
• Higher frequency pulses with narrower sonar beam coverage reveal more details, but
cannot penetrate deep water.
• Lower frequency pulses with wider beam coverage penetrate deeper but reveal less
detail.
Traditional sonar sends only one frequency at a time, resulting in restricted clarity and
resolution. More advanced CHIRP sonars transmit a sweeping range of frequencies,
providing better target separation and higher definition.
1 Press [MENU] > Sonar Setup > Frequency .
2 Use the main knob or the control pad to highlight a frequency.
3 Press [SELECT] to adjust the highlighted frequency.
