Revision 1.11
Figure 6 contains several examples of over-the-side mounts. For added
stability, it is recommended that lines connected to the flange be tied off
forward and aft.
The tilting aluminum deck plate design shown in Figure 6 is also shown
with the transducer fully deployed and in the stowed position. For added
support, it is advisable to secure the mounting pole at two points
whenever possible or tie a line or cable forward and aft from the flange.
ECHOSCAN transducers are normally delivered with 50 feet (or 15
meters) of cable. Proper routing of cables should be a priority
consideration when planning a new installation. Deck cable extenders of
variable lengths are available from Odom.
