SI-TEX Transducers

SI-TEX transducers send and receive the sonar signal your SI-TEX sounder reads, in thru-hull, transom-mount, bronze and Lexan housings. Match the model and frequency to your specific sounder. Choosing a SI-TEX Transducer Start with your sounder model. SI-TEX transducers are listed for specific units such as the CVS and SDD series, and a transducer must match the sounder it plugs into. Check the model fitment note in the listing before you order. Next choose a mount style. Thru-hull transducers give the cleanest signal and best deep-water performance but need a hole through the hull, with bronze for fiberglass and wood and Lexan for metal hulls.

Choosing a SI-TEX Transducer

Start with your sounder model. SI-TEX transducers are listed for specific units such as the CVS and SDD series, and a transducer must match the sounder it plugs into. Check the model fitment note in the listing before you order.

Next choose a mount style. Thru-hull transducers give the cleanest signal and best deep-water performance but need a hole through the hull, with bronze for fiberglass and wood and Lexan for metal hulls. Transom-mount models bolt to the back of the boat and suit trailer boats and smaller hulls. Frequency matters too, with 50 kHz reaching deeper and 200 kHz showing more detail in shallow water. Pick a dual-frequency model if you fish both.

Frequently Asked Questions

How do I know which SI-TEX transducer fits my sounder?

Each transducer is listed for specific SI-TEX units like the CVS and SDD series. Match the listed fitment to your sounder model before ordering.

Thru-hull or transom mount?

Thru-hull gives the best deep-water signal but needs a hull penetration. Transom mount bolts on the back and suits trailer boats and smaller hulls.

What does 50/200 kHz mean?

It is a dual-frequency transducer. The 50 kHz signal reaches deeper water while 200 kHz shows finer detail in the shallows.
