2.1.3 - Installing the StrataBox Transducer
General Transducer
The StrataBox is equipped with a single lightweight, Line-in-Cone transducer that is designed for
portable, over-the-side mount applications. It may also be used in permanent installations but will need to
be mounted in a water filled seachest in those installations. Before installing the transducer, the installer
should read and understand the appropriate section below to insure that all of the installation issues are
considered.
Selecting a Location for the Transducer
The location of the transducer is very important for maintaining reliable bottom tracking and optimum
subbottom performance of the equipment. Avoid installing transducers in locations where the transducer
will be subjected to turbulent water, air bubbles, or vibration. The best clear water location on most
vessels meeting these criteria is approximately 1/3 the length of the vessel, aft from the bow.
For many portable applications and some permanent applications it is not practical to mount the
transducer in the forward section of the vessel. For these applications the transducer can be located in the
aft third of the vessel; away from and forward of shafts and propellers, clear of hull openings, sea chests,
outlets or protuberances. It is preferable to mount the transducer on the side of the hull where the
propeller blades are normally moving downwards. The upward motion of the propeller can generate
pressure waves, which push air bubbles up against the hull. By mounting the transducer on the downward
side, the hull will tend to protect the transducer from this effect.
