Transducer installation
37
857-164688 / E
Large diameter transducers must be fitted with a horizontal
support bar. This bar can then be secured to the mounting ring
using threaded rods.
→ Refer to figure 6.
The transducer cable penetrates the hull in a stuffing tube. Leave
an adequate loop of the cable behind the transducer for easy
mounting or removal of the transducer.
Figure 7 Blister toe-in
towards the keel
Observe the horizontal and vertical distances (X and Y) between
the keel and the transducer blister. On a medium sized vessel,
the horizontal distance (X) should be approximately 1 meter.
The vertical distance (Y) must in general be as small as possible.
This is important to prevent the keel from shadowing the
transducer beam in shallow waters.
