130 - 210 kHz

Follow the precautions below for optimal

product performance and to reduce the risk of

property damage, personal injury, and/or death.

WARNING: Always install the two set screws with

marine sealant applied to the threads. This will hold

the hull nut firmly in place. Failure to do so may allow

the hull nut to become loose.

WARNING: Always wear safety goggles and a dust

mask when installing.

WARNING: Immediately check for leaks when the

boat is placed in the water. Do not leave the boat

unchecked for more than three hours. Even a small

leak may allow considerable water to accumulate.

WARNING: Stainless steel housing in a metal hull—

Be sure the washer contacts the hull. Do not tighten

the hull nut with the washer against the isolation

bushing, as the housing will not be firmly installed. If

necessary, sand the isolation bushing until the washer

rests against the hull.

CAUTION: CHIRP transducer—Do not install in the

engine compartment or other hot place. The

transducer may fail if it overheats.

CAUTION: CHIRP transducer—Always operate the

transducer in water. Operating in air will allow the

transducer to overheat resulting in failure.

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.

CAUTION: Never install a metal transducer on a

vessel with a positive ground system.

CAUTION: Never pull, carry, or hold the transducer by

its cable; this may sever internal connections.

CAUTION: Stainless steel housing in a metal hull—

Stainless steel housing must be isolated from a metal

hull to prevent electrolytic corrosion. Use the isolation

bushing supplied.

CAUTION: Never use solvents. Cleaners, fuel, sealants,

paint, and other products may contain solvents that can

damage plastic parts, especially the transducer’s face.

IMPORTANT: For optimal performance, apply marine

sealant to the entire inside surface of the spacer. This

will fill the gap between the spacer and the sidewall of

the transducer preventing vibration.

IMPORTANT: Read the instructions completely

before proceeding with the installation. These

instructions supersede any other instructions in your

instrument manual if they differ.

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.

Match Tilt Angle of Transducer to Deadrise

Be sure your transducer model matches the deadrise angle of

your hull at the selected mounting location. The tilt angle is printed

on the top of the transducer (see Figure 1). To measure the

deadrise angle of your hull at the selected mounting location, use

an angle finder or a digital level (see Figure 2).

• 0° transducer for deadrise angles from 0° to 7°

• 12° transducer for deadrise angles from 8° to 15°

• 20° transducer for deadrise angles from 16° to 24°
