Dual Beam Ice Transducer
(optional-purchase XI 9 20 Ice Transducer only)
Your Fishfinder 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.
