Digital Depth Source (Advanced, Down Imaging® Models With Optional-Purchase Transducers Only [688Ci Hd Di]) - Humminbird 688ci HD DI Operation Manual

Digital Depth Source specifies the beams that will be used to provide the
depth for the digital depth readouts (see Views and Setup Menu Tab: Select
Readouts for more information). It is important to set this menu option based
on the transducer that is connected to the control head, as follows:
• If a Down Imaging® transducer is connected to the control head, select
Auto. Depending on the depth, Auto will automatically choose the 2D
conical beams or the Down Imaging® beams to display depth in the
digital readout window. Auto is the default setting.
• If an accessory transducer is connected to the control head, select 2D
Element. For example, if you connect an ice transducer to your Down
Imaging® unit, change the digital depth source to 2D Element in order
to display depth in the digital readout window. The 2D Element setting
should not be used with a Down Imaging® transducer.
NOTE: Visit our Web site at humminbird.com to determine which accessory
transducers are compatible with your Humminbird® Fishing System, or Contact our
Customer Resource Center.
NOTE: When Digital Depth Source is set to 2D Element, the DI setting will be
removed from the DI Pings menu. When DI Pings is set to DI, the 2D Element
setting will be removed from the Digital Depth Source menu. See DI Pings for
more information.
