B164 12 degree

Dual Frequency
The dual-frequency B164 includes an array of three ceramic elements delivering both 50 kHz with a 22° port/starboard beam width (20° fore/aft), and 200 kHz with a 6° beam width. 50 kHz low-frequency operation offers a maximum operational depth of 900 m (3000 ft), while 200 kHz high-frequency provides higher-resolution fish arches and bottom detail in shallower water.

Depth/Temperature
One sensor does it all. Able to measure both depth and temperature in a single package, the B164 simplifies installation and requires just one connection to your echosounder module or multifunction display.

Deadrise Compensation
The B164 is also available in 12° and 20° fixed tilt versions to compensate for hull deadrises of 8-15° and 16-24° respectively. With ceramic elements tilted inside the housing to aim the beam straight down without a fairing block, these transducers are able to deliver more accurate depth readings and best cover the area directly beneath your boat.

Mounting
With bronze housing, the B164 is suitable for thru-hull mounting in fiberglass and wood hulls. Thru-hull mounting places the transducer in the water on the outside of your boat’s hull; a hole must be drilled for installation. This typically offers the best depth measurement and fishfinding performance.
