B275LH-W Bronze Thru-Hull - Low & High Wide Frequency Get more coverage under the boat with the wide beam CHIRP product line. Offering a high frequency range of 150-250 kHz and a constant 25° beam width, these transducers are truly broadband at its best. In addition to improving the performance of CHIRP-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency CHIRP transducers. A unique property of the high frequency transducers is that the beambwidth is a constant 25° angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with the narrow beam transducers, the wide beam format also creates crisper and larger return images on the display. We've got you covered! Features: * Depth and Temperature * 42-65kHz L Frequency * 150-250kHz H Frequency * Bronze * 1kW * Wide 25° Beam * Requires extension cable A80327
