How to install the transducer

Example: Medium sized transducer without
clamping ring

The illustration below shows a transducer blister designed for a
medium sized transducers. The same blister design principles
apply. Note that the transducer is mounted without a clamping
ring, which makes it necessary to use a different mounting ring
design.

Note that the transducer cable must be provided with a cable loop
inside the blister. Observe the vertical forward edge of the blister.
This will guide the water to each side of the blister.
