3. Tape the transducer to a pole with the cable side up. Hold it over
the side of the boat with the active face submerged in the water
(see Figure 2-12 ). Keep the active face of the transducer parallel
to the surface of the water.
4. Observe the Fishfinder’s performance and depth reading.
Figure 2-12: Establishing a Performance Baseline
Testing the Mounting Location
While the boat is moving around the same site (and depth of water),
test the transducer at your selected mounting location inside the hull.
Use one of the methods below:
1. This method is recommended if the sensor will be located near the
stern and the boat has a minimum deadrise angle.
i.
Clean away any large build-up of dirt and/or grease using
detergent or a weak solvent such as alcohol.
ii. Place the sensor against the hull and allow bilge water to cover
the surface where they touch (see Figure 2-13 A).
WARNING:
Always wear safety goggles and a dust mask.
2. This method can be used at all hull locations.
i. If the hull surface is not smooth, grind it with a disc sander.
ii. Partially fill a thin plastic bag with water, place the sensor
inside the bag and close it tightly with a twist-tie.
iii. Wet the surface of the hull and press the sensor face against it
through the bag (see Figure 2-13 B).
