Each transducer, featuring a robust bronze housing, integrates CHIRP technology across the low (40-60 kHz) and medium (80-130 kHz) frequency bands, offering versatility for deep-water and coastal detection. The B175LM transducer provides depth and temperature data essential for navigation and fishing.\n\u003c\/p\u003e\n\n\u003ch3\u003eCHIRP Performance and Adaptability\u003c\/h3\u003e\n\u003cp\u003e\n    With 1 kW power, the B175LM delivers superior target resolution and improved echo separation compared to conventional 600 W transducers such as the B75 series. The low band (40-60 kHz) is optimized for deep-water penetration, with a variable beam angle ranging from 24° to 16°. The medium band (80-130 kHz) ensures detailed fish and structure detection in intermediate depths, with a beam angle of 16° to 11°. Each transducer in the pack features a 20° tilted ceramic element, correcting hull angle for vessels with a deadrise between 16° and 24°, ensuring a precise vertical beam for optimal readings.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and Positioning\u003c\/h3\u003e\n\u003cp\u003e\n    This transducer pack integrates with Raymarine CHIRP depth sounder systems, including CP470 and CP570 modules, and multifunction displays from the Axiom and Element Pro ranges. Unlike a B75 transducer, which offers 600 W, the 1 kW B175LM is intended for applications requiring higher power and depth capability. The inclusion of two identical transducers in this pack (T70076) allows for advanced configurations, such as use with two separate sounder modules for extended coverage or redundancy, or for large vessels requiring multiple measurement points for comprehensive seabed mapping. Compared to transducers like the Airmar TM150M (600 W, transom-mount, medium frequency only) or the B260 (1 kW, fixed dual-frequency, non-CHIRP), the B175LM offers modern CHIRP technology with a discreet and high-performance through-hull installation.\n\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":55902180573524,"sku":"T70076","price":3562.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main-square_7bd0e9cd-9f82-4395-a9b3-5037c7b784d9.jpg?v=1779383722","url":"https:\/\/skysat.fr\/en-us\/products\/raymarine-pack-of-two-b175-d-t-low-medium-20-degree-through-hull-transducers","provider":"Skysat","version":"1.0","type":"link"}
