Humminbird 710273-1 XI 9 1521 Ice Transducer

My buddys Markum causes this to have significant interference.

As described

Completely faulty ducer. Had to call humminbird and get a new one sent out. On back order wont get a working unit for 3 plus weeks.

Perfect ducer for mega imaging units

Works great with the helic models!

Works good exactly what I wanted

Works perfect for converting helix 7 to ice!

Just as what I expected, with my Helix 5 chirp G2, can see my baits falling and fish approaching.

Works great on my Helix 7

nice add. for ice fishing
