Notes
Applications
• Bronze housing recommended for fiberglass or wood hulls. Never install a bronze housing in an aluminum hull, because electrolytic corrosion will occur.
• Stainless steel housing compatible with all hull materials. Recommended for metal hulls to prevent electrolytic corrosion provided the stainless steel housing is isolated from the metal hull.

Warning
CAUTION: Chirp transducer—Always operate the transducer in water. Operating in air will allow the transducer to overheat resulting in failure.

Alert
CAUTION: The arrow on the top of the transducer must point toward the keel or centerline of the boat. This will align the angle of the element inside the transducer with the deadrise angle of your hull.
