CH-250BB specifications

The Furuno CH-250BB is a state-of-the-art fish finder designed for both commercial and recreational fishing. This high-performance sounder is renowned for its advanced technology, offering users exceptional depth and accuracy in their fish-finding endeavors.

One of the standout features of the CH-250BB is its powerful 1 kW output, which enables it to deliver impressive results at depths of up to 1,500 meters (or about 4,900 feet). This depth capability benefits users targeting various fish species that inhabit deeper waters. Its dual-frequency operation allows for flexibility, as it can operate on both 28 kHz and 200 kHz frequencies. The lower frequency excels at deep-water applications, while the higher frequency provides superior resolution for shallow-water fishing.

The CH-250BB utilizes Furuno's advanced digital signal processing technology, which significantly enhances target detection and separation. This technology allows for better noise rejection and improved clarity, making it easier to distinguish between fish and other underwater structures. The user-friendly interface further complements its performance, featuring intuitive controls and customizable display options to cater to individual preferences.

Another notable characteristic of the CH-250BB is its robust construction, designed to withstand the rigors of marine environments. The waterproof and corrosion-resistant housing ensures reliable operation, even in challenging conditions. Additionally, the unit is equipped with an integrated transducer that delivers high-quality sonar performance and accurate readings.

Furuno’s proprietary echo sounder algorithms also play a crucial role in the CH-250BB's performance. These algorithms are finely tuned to provide accurate fish size estimates and depth readings, assisting fishermen in making informed decisions.

Moreover, the CH-250BB comes equipped with a variety of output options, including video output, allowing for seamless integration with other marine electronics. This feature adds to its versatility, making it an ideal choice for both serious anglers and commercial fishers.

In conclusion, the Furuno CH-250BB is a powerful and reliable fish finder that combines advanced technology, robust construction, and user-friendly design. Its impressive features, such as high output power, dual-frequency capability, and advanced signal processing, make it an essential tool for anyone serious about fishing. Whether navigating deep waters or exploring coastal regions, the CH-250BB is engineered to deliver exceptional performance and reliability on the water.
