With its 12-degree profiled element, this transducer fits hulls with a deadrise angle of 8 to 15 degrees, eliminating the need for an additional fairing block and simplifying installation.\n\u003c\/p\u003e\n\u003ch3\u003eLow-frequency CHIRP performance\u003c\/h3\u003e\n\u003cp\u003e\n    The \"L\" designation in B175L indicates operation at low frequency (Low CHIRP), typically in the 40 to 60 kHz range. This frequency range is particularly suited for deep-water detection, allowing significant depth penetration while maintaining effective target resolution. Unlike \"M\" (Medium CHIRP, 80-130 kHz) or \"H\" (High CHIRP, 130-210 kHz) transducers, which offer better target separation at shallower depths, the B175L excels in water column penetration and deep-sea floor detection. It differs from B175M or B175H models by providing reliable data for deep-sea fishing or exploration of deep structures.\n\u003c\/p\u003e\n\u003ch3\u003eDesign and integration\u003c\/h3\u003e\n\u003cp\u003e\n    Made of bronze, this through-hull transducer (BB TH for \"Bronze Through-Hull\") is robust and resistant to marine environments, suitable for fiberglass or wooden hulls. Its 12-degree profiled design ensures a vertically oriented beam even on an angled hull, optimizing detection performance. This model is an essential component for Raymarine CHIRP-compatible chartplotters and fishfinders, integrating seamlessly with Axiom, Element multifunction displays, or other units compatible with Raymarine’s CHIRP technology. For installations where through-hull mounting is not possible, alternatives such as transom-mount transducers (e.g., TM185L) exist, but the through-hull solution of the B175L offers superior hydrodynamic performance and enhanced sensor protection.\n\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":55863105552724,"sku":"A80045","price":1293.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main-square_4b3c3670-9bb7-42ae-8f83-db09dd07aef8.jpg?v=1779217343","url":"https:\/\/skysat.fr\/en-gb\/products\/raymarine-b175l-bronze-through-hull-transducer-12-degree-chirp-fishfinder","provider":"Skysat","version":"1.0","type":"link"}
