Frequently Asked Questions
What are the advantages of dual-frequency CHIRP over single frequency transducers?
Dual-frequency CHIRP provides both deep-water penetration (low frequency) and high-resolution detail (high frequency) in one transducer. The 42-75kHz range excels at deep water and large fish detection, while 130-210kHz delivers superior target separation and structure detail.
What hull types and deadrise angles are compatible with this transducer?
The B265LH is designed for fiberglass and wood hulls with deadrise angles from 0° to 20°. A fairing block is included to ensure proper acoustic alignment and optimal performance across this range of hull configurations.
How accurate is the integrated temperature sensor?
The B265LH features a highly sensitive water temperature sensor that provides accurate temperature readings essential for locating thermoclines, understanding fish behavior patterns, and optimizing fishing strategies based on water temperature preferences of target species.
Which Raymarine sonar modules are compatible with this transducer?
The B265LH is compatible with Raymarine CP450C, CP470, and CP570 CHIRP sonar modules. The 33-foot cable includes the proper connector for direct connection to these professional sonar systems.
Why choose bronze construction over plastic for a thru-hull transducer?
Bronze construction provides superior corrosion resistance in saltwater, excellent thermal stability for consistent acoustic performance, and enhanced durability against underwater impacts. Bronze maintains its acoustic properties over time and resists the electrolysis issues common with lesser materials.
What is the maximum power handling capability of this transducer?
The B265LH handles up to 1,000 watts of power, providing maximum performance for deep-water applications and enhanced target detection. The 8 internal ceramic elements efficiently handle this power level for professional-grade sonar performance.
