455 kHz Balance

(Advanced, with QuadraBeam™ Transducer)
455 kHz Balance 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™ transducer must be attached to the 700 Series™ Fishing
System. The 455 kHz Balance 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 Balance requires the purchase of the QuadraBeam™ 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 Balance 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 Balance setting:
1. Make sure you have selected QuadraBeam
then highlight 455kHz Balance on the Sonar Main Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz Balance.
