3.0.2 Transducer Types
Since there are many different shapes and sizes of hulls, STANDARD HORIZON offers a
range of Depth transducers to fit the vessels requirements.
3.0.3 Low Profile Thru-Hull
If the user is planning to mount a thru-hull transducer first he has to know the dead rise angle
where the transducer will be located on the boat. The "Dead Rise" is a nautical term that refers
to the angle of the hull where the transducer will be mounted (see picture below). Specific
transducers are designed to be installed on boats with different dead rises.

3.0.4 Transom
(
POWER
BOATS
ONLY
)
The back of a boat is called the transom this is where this transducer is mounted. This
transducer has a bracket that is screwed down onto the hull.
3.0.5 Fairing Block
Used when a hull is over 10-15 degrees.
·
The Fairing Block is used to compensate the dead rise of the hull. The Fairing Block
STANDARD HORIZON offers is made from hard plastic which fits around the
transducer.
·
To install the transducer and Fairing Block, the user measures the dead rise of the
hull and cuts the Fairing Block to that angle. One half of the Fairing Block mounts on
the inside while the other part of the Fairing Block mounts on the outside of the hull.
3.0.6 In-hull
This transducer is epoxyed to the inside of the hull that is not more than 1/2 inch thick and
is solid not cored.
