Through Hull

Through Hull transducers require that a hole is cut in the hull, so their installations is more involved. Due to their location, they are also more difficult to access for periodic cleaning. Installations on trailer boats must be planned very careful to ensure that they do not get damaged by the trailer rollers or supports.

To ensure best performace, care must be taken to keep the transducer facing squarely downwards into the water. This is accomplished by installing a fairing block or selecting one of the through hull models that offer the tilted element.

A fair amount of skill is required to achieve a proper through hull installation. If in doubt consult your local boat builder or shipwright to assist you.
