Dual Beam Ice Transducer
(optional-purchase XI 9 20 Ice Transducer only)
Your Fishing System supports the optional-
purchase XI 9 20 Ice Transducer which
provides selectable dual-frequency sonar
with a wide area of coverage. Selectable
dual-frequency gives you the option of two
beams, and both beams will cover the
bottom and provide high definition. The
20° center beam provides the highest
definition, while the 60° beam provides
wider coverage. Depth capability is
affected by such factors as bottom
hardness and water conditions. Whether
fishing in shallow or very deep water,
selectable dual-frequency is ideal for a
variety of conditions.
