This unit features a 20° tilted element to compensate for hull angles from 16° to 24°, ensuring a vertically oriented acoustic beam for optimal performance. It provides rapid-response depth and water temperature data via an 8-pin connector compatible with Garmin systems.\n\u003c\/p\u003e\n\u003ch3\u003eCHIRP technology and acoustic performance\u003c\/h3\u003e\n\u003cp\u003e\n    The embedded CHIRP technology enables the B75H to offer superior target separation and improved seabed detail resolution compared to fixed-tone transducers. Its high-frequency band (130-210 kHz) is particularly suited for detecting fish in complex structures or shallow waters, with a beam width ranging from 15° to 9°. The 600 W power allows reaching a maximum depth of 214 meters (700 feet), which is relevant for coastal and mid-depth fishing. The B75H differs from the B75L (low frequency) and B75M (mid frequency) models by focusing on high frequency, providing enhanced image resolution at the expense of very deep penetration.\n\u003c\/p\u003e\n\u003ch3\u003eDesign and installation\u003c\/h3\u003e\n\u003cp\u003e\n    The bronze housing of this transducer is specifically recommended for fiberglass or wooden hulls and must not be installed on metal hulls to avoid electrolytic corrosion. Its low-profile through-hull design is suitable for small and medium-sized boats, including center consoles, and aims to maintain stable display resolution even at high speeds. Installation requires a 70 mm (2-13\/16 inches) hole in the hull. Like other Airmar Tilted Element™ transducers (available in 0°, 12°, and 20°), selecting the tilt angle is critical to match the boat's keel angle, ensuring the B75H transducer transmits and receives signals directly beneath the vessel. The transducer also integrates Airmar’s Xducer ID® technology for automatic recognition by compatible devices.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"20 degrees","offer_id":55860599783764,"sku":"010-11634-22","price":795.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_844eb1d7-4993-4f1b-86d3-acfff1a9a537.jpg?v=1779194904","url":"https:\/\/skysat.fr\/en\/products\/garmin-airmar-b75h-through-hull-bronze-chirp-transducer-600w-20deg","provider":"Skysat","version":"1.0","type":"link"}
