Lowrance Structurescan HD LSS-2 Transducer.
Good working condition.
Was used on my boat but changed to a different unit as someone who cannot cast put a sinker thru my unit display.
Who shall remain nameless and onshore next time.
Cables can be joined once its pulled thru the hull.
( I have done this before very easy. Each cable has its own color. Better than drilling large holes ).
