5. Remove the transducer from the water. Use one of the methods below to test
the depth readings with the transducer at the desired in-hull location selected
in Step 1.
A.
If the hull surface is not smooth, sand it with 30 grit sandpaper until a
smooth surface is obtained. Partially fill a thin plastic bag with water,
place the transducer inside and close it tightly with a tie wrap. Wet the
surface of the hull and press the transducer face against the hull through
the bag. Proceed to # 6.
B.
If the transducer will be located in an area in the hull that holds water,
place the transducer against the hull and allow bilge water to cover the
surface where the transducer touches the hull. Proceed to # 6.
C.
If the hull surface is not smooth, sand it with 30 grit sandpaper until a
smooth surface is obtained. Coat the face of the transducer with
petroleum jelly and press it against the hull with a twisting motion. Use
duct tape to hold it in place. Proceed to # 6.

One of the easiest ways to
temporarily secure the transducer
in hull is by following 5-B and
wrapping the cable around the
transducer as pictured.
6. If “---” readings appear or the readings are noticeably different from the
depth displayed when the transducer was hung over the side of the boat, you
will need to find another location. If the readings are similar mark the spot in
the hull and proceed to # 7.
7. Temporarily anchor the transducer on the marked spot using duct tape.
8. Remove the vessel from its mooring and operate it at idle speeds while
getting to know the functions and performance of the depth sounder.
9.
Gradually increase the boat speed and observe the depth readings
(make
sure you stay in water between 2.5 and 200 feet deep).
10. If “---” readings appear:
•
Put the vessel in a slow turn. If “---” disappears when turning, the
transducer’s position probably needs adjustment because it is in aerated
water.
•
If “---” does not disappear while turning, relocate the transducer using any
one of the methods in # 5 and repeat #5 thru #10.
•
If following 5-B, make sure that your “---” readings are not caused by the
bilge water flowing away from the transducer face while turning,
accelerating or decelerating.
