Pack de dues sondes travesseres B175 D/T Medium-High 20°

CHIRP (Compressed High-Intensity Radiated Pulse) technology allows these B175 transducers to scan a wide range of frequencies instead of emitting on a single fixed frequency. This provides several major advantages:

Better target separation: It allows clearer distinction between individual fish or objects close to each other.Superior image clarity: Seafloor and underwater structure images are sharper and more detailed.Improved detection: The ability to detect fish and structures is enhanced, even in challenging conditions.

The Medium-High (MH) designation for the frequency band of these B175 depth sounders indicates that they operate within an intermediate frequency range, typically between 85 and 135 kHz. This band is particularly effective because it offers an excellent balance between:

Depth penetration: Sufficient for detecting fish at various depths.Detail resolution: Allows for good identification of structures and fish schools.It is optimized for sport fishing and fish finding in varied water columns.

Including two B175 D/T Medium-High through-hull transducers in this pack provides several key benefits:

Extended coverage: Delivers a wider underwater view, ideal for large vessels.Signal redundancy: Enhances reliability, allowing one transducer to take over if the other fails.Improved side vision: Useful for sport fishing applications where detailed side views of the water column are required.Turbulence compensation: Helps maintain a clear signal even in turbulent water conditions, particularly on fast boats or in choppy seas.

This setup is especially recommended for vessels over 12 meters or for applications requiring high-resolution side imaging.

Note: Installation requires two hull penetrations and compatible NMEA 2000 or dedicated sonar interfaces.

D/T functions mean that each transducer can measure and transmit two essential types of data simultaneously:

Depth (D): It provides accurate information on the distance between the boat's hull and the seabed, crucial for navigation and fishing.Temperature (T): It measures the water temperature at the transducer's location, a key data point for understanding fish movements and oceanographic conditions.These combined data points offer comprehensive monitoring of marine conditions.

These through-hull transducers feature a 20-degree tilt angle and are specifically optimized for hulls with a deadrise angle (or hull V-angle at the transducer location) between 16 and 24 degrees. This predefined angle ensures the transducer's acoustic beam is emitted and received perpendicular to the water surface, maximizing depth and temperature reading performance and accuracy.

The B175 D/T Medium-High through-hull transducers are primarily designed for installation on fiberglass and wood hulls. For metal hulls (aluminum or steel), installation requires specific precautions to prevent galvanic corrosion. This may include using plastic housings or isolation kits to separate the transducer body from the metal hull.

These B175 D/T Medium-High through-hull transducers are fully compatible with the following Raymarine CHIRP fishfinder modules:

Raymarine CP470Raymarine CP570These modules are required to process and interpret the high-performance CHIRP data provided by the transducers.

No, these B175 transducers cannot be connected directly to Raymarine Axiom or Element multifunction displays. They are designed to connect to an external Raymarine CHIRP sounder module, such as the CP470 or CP570. This sounder module then connects to your Axiom or Element multifunction display, enabling the display of depth and temperature data with full CHIRP technology performance.
