In ClearVü mode, it delivers precise definition of structures beneath the boat, facilitating the identification of promising fishing areas. Its beam widths are 24°\/13° for traditional sonar and 2.0°x51° at 260 kHz and 1.4°x29° at 455 kHz for ClearVü, enabling detailed coverage.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and Marine Performance\u003c\/h3\u003e\n\u003cp\u003e\n    With its stainless steel construction, the GT23M-TH transducer is suited for demanding marine environments. Its transom-mount design, paired with a fairing block, allows installation on hulls with a deadrise angle up to 25°, ensuring optimal beam orientation for stable sonar performance even in rough conditions. This transom-mount configuration is generally preferred over transducers mounted on the transom board for its robustness and better hydrodynamic performance during high-speed navigation or in rough seas.

The ClearVü Ultra High Definition mode uses a CHIRP range of 760–880 kHz (nominally 800 kHz) with 500 W power, providing a maximum depth of 200 feet. Its 0.76° x 46° beam at 800 kHz, featuring a downward-facing element, concentrates more power on targets for precise detection below the boat.

It is recommended for hulls with a deadrise angle up to 5° for direct installation but can be installed on angles up to 25° using a fairing block. This versatility sets it apart from in-hull transducers, which are limited to solid fiberglass hulls and typically do not provide temperature data. Installation requires hull penetration and the use of included anti-rotation bolts, ensuring a stable and durable mount. A Garmin display software update is required when installing this device to ensure optimal performance.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"","offer_id":55860638712148,"sku":"010-12776-10","price":592.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_5c649ecf-f134-49c0-a8c5-46553594faad.jpg?v=1779195531"}],"url":"https:\/\/skysat.fr\/en-tr\/collections\/thru-hull-transducers.oembed?page=2","provider":"Skysat","version":"1.0","type":"link"}
