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.
6.0.3

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. See Par. 6.1.
6.0.4 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.
6.0.5

Fairing Block

Used when a hull is over 10-15 degrees this type of transducer should be used.
· What makes this transducer different from a Low Profile transducer is that it is used with
a fairing block.
· The Fairing block is used to compensate the dead rise of the hull. The fairing block
