The dual-frequency PDT-WBL includes a single ceramic element delivering both 83 kHz with a 52° beam width, and 200 kHz with a 22° beam width. 83 kHz low-frequency operation offers a maximum operational depth of 300 m (1000 ft), while 200 kHz high-frequency provides higher-resolution fish arches and bottom detail in shallower water.
One sensor does it all. Able to measure both depth and temperature in a single package, the PDT-WBL simplifies installation and requires just one connection to your echosounder module or multifunction display.
The PDT-WBL is suitable for in-hull mounting in fiberglass hulls, or trolling-motor mounting with any hull type.
In-hull or “shoot-thru-hull” transducers don’t require a hole to be drilled in your boat’s hull for installation, and offer good high-speed performance and ease of maintenance, but reduced maximum depth and fishfinding performance versus thru-hull, transom, or other in-water installations.
Trolling motor-mounting is quick and easy, providing superior performance to in-hull (shoot-thru) installations while requiring no holes to be drilled in the hull or transom.
