The tube should be unbroken and watertight from the transducer
to above the water line. From there, openings or a junction box
can be installed to facilitate drawing of the cable, or to add a
cable extension. However, the tube should act as a continuous
electrical screen all the way and be connected to the transceiver
chassis.
Tube dimensions:
• Minimum 35 mm inner diameter
• Minimum 6 mm wall thickness (4.5 mm if galvanised).
If two or more transducers are installed close to each other it is
possible to pull their cables in the same steel tube, provided the
tube diameter is increased accordingly. However, for easy
replacement it is recommended that each transducer has its own
steel tube.
