1.5.2

Remarks on installation

• Turn off the engine and anchor the boat while installing the equipment.

1.5.3 Mounting location
Keep the following points in mind when selecting a mounting location:
• The mounting location should be where the hull is of single-hull thickness and is
void of air or flotation materials other than solid fiberglass between the transducer
face and the water.
• Do not place the transducer over hull struts or ribs which run under the hull.
• Avoid a location where the rising angle of the hull exceeds 15°, to minimize the
effect of the boat's rolling.
• You will finalize the mounting location through some trial and error. The procedure
for this is shown later.
