455 kHz Sensitivity

(Advanced: with QuadraBeam PLUS™ transducer)

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 455 kHz 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 our Customer Resource Center at 1-800-633-1468.

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 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)
