455 Khz Sensitivity (Advanced, With Quadrabeam Plus™ Transducer) - Humminbird 717 Operation Manual

531524-1_A - 717 & 727 Man_Eng.qxp
455 kHz Sensitivity adjusts the sensitivity of the 455 kHz beam. Increasing the
sensitivity will display additional weak returns and decreasing the sensitivity
will display fewer weak returns. A QuadraBeam PLUS™ transducer must be
attached to the Fishing System. The 455 kHz Sensitivity menu choice is
available when Transducer Select is set to QuadraBeam (see Sonar Menu Tab:
Transducer Select) and User Mode is set to Advanced (see Setup Menu Tab:
User Mode).
:
NOTE The 455kHz Sensitivity requires the purchase of the QuadraBeam PLUS™ transducer.
You can visit our website at www.humminbird.com to order this accessory online or contact

NOTE: 455 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 455 kHz
sonar returns in the Side Beam View. The 455 kHz sensitivity can be adjusted without affecting
the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window.
To change the 455 kHz Sensitivity setting:
1. Make sure you have selected QuadraBeam PLUS™ Transducer and
Advanced Mode and that the QuadraBeam PLUS™ transducer is
connected, then highlight 455 kHz Sensitivity on the Sonar Main Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz
Sensitivity. (-10 to +10, Default = 0)
