6.0.2Transducer Types

Since there are many different shapes and sizes of hulls, STANDARD HORIZON offers a range of Depth transducers to fit the vessels requirements.

6.0.3Low 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.

6.0.4Transom

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.

6.0.5Fairing 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 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.
