Detailed description

Skersinė Garmin GT17M-THF 20° sonda skirta užtikrinti patikimą ir stabilų CHIRP sonaro veikimą, specialiai pritaikyta laivams su varangos (deadrise) kampu tarp 17 ir 24 laipsnių. Pagaminta iš nerūdijančiojo plieno, ši sonda užtikrina ilgaamžiškumą ir suderinamumą su įvairiais korpuso medžiagomis, įskaitant stiklaplastikį, medį, kompozitus, aliuminį ir plieną.

Įrengimo ir korpuso medžiagų suderinamumas

GT17M-THF sonda reikalauja ypatingo dėmesio įrengiant ją į korpusą. Aliuminio ar plieno korpusams būtina naudoti įtrauktus galvaninės izoliacijos komponentus, siekiant užkirsti kelią galvaninei korozijai ir vandens įsiskverbimui aplink sondą. Šis reikalavimas atskleidžia Garmin sumanų dizainą, skirtą saugiam ir ilgaamžiškam integruotam įrengimui, priešingai nei paprastesnės sondos, kurios gali neteikti šio esminio apsaugos lygio metaliniuose korpusuose. Rekomenduojama, kad įrengimą atliktų kvalifikuotas jūrinis technikas, siekiant užtikrinti optimalų veikimą ir išvengti bet kokių pažeidimų.

Veikimo optimizavimas ir pozicionavimas

GT17M-THF 20° modelis skiriasi nuo 0° ar 12° versijų tuo, kad tiksliai kompensuoja specifinį varangos kampą, užtikrindamas, kad transduktoriaus elementas būtų teisingai orientuotas į dugną, siekiant maksimalaus aptikimo. Stiklaplastikio korpusams reikalingas 98 mm skylės diametras, o metaliniams korpusams – 101 mm. Sonda turi būti įrengta vietoje, kurioje vanduo yra švarus, be sūkurių, sukeliamų propelerių, kilio, vandens įsiurbimo angų ar kitų įrenginių. Optimalus pozicionavimas yra esminis: prie variklio priekio – išoriniams varikliams, toli nuo propelerio – vidiniams varikliams, arba tarp variklių – dvigubų variklių atveju. Po įrengimo būtina atlikti Garmin žemėlapio įrenginio programinės įrangos atnaujinimą, kad būtų užtikrintas suderinamumas ir maksimalus veikimas. Reguliarus priežiūra naudojant vandenyje besilaikančią antifoulingo dažų dangą ir be agresyvių tirpiklių valymas pailgins sondos eksploatacijos trukmę.

« Technical analysis of the Garmin GT17M-THF 20° through-hull transducer »

The Garmin GT17M-TH 20° transducer is a high-quality through-hull solution for demanding marine applications. Its stainless steel construction provides superior robustness, essential for reliability in marine environments, especially when compared to less impact- and wear-resistant plastic models. The inclusion of galvanic isolation components for metal hulls (aluminum, steel) is a major technical advantage, ensuring effective protection against corrosion and long-lasting waterproofing—a critical feature often overlooked in less specialized equipment.

This model is specifically calibrated for deadrise angles of 17° to 24°, making it a precise choice for hulls with this geometry. Installation must comply with Garmin guidelines, including the use of marine sealant and correct orientation (arrow pointing toward the keel), to fully utilize its capabilities. While installation requires hull drilling (98 mm for fiberglass, 101 mm for metal) and demands some expertise, the benefit in terms of undisturbed CHIRP sonar signal is significant compared to transom-mount transducers. Signal quality, crucial for identifying structures and fish, is directly tied to installation in a laminar flow zone. The requirement for a chartplotter software update underscores this transducer’s system integration, ensuring compatibility and optimal performance within the Garmin ecosystem.

Frequently asked questions

Need help? Contact us

What is the Garmin GT17M-THF 20-degree through-hull transducer and what is it used for?

The Garmin GT17M-THF 20-degree through-hull transducer is a transducer designed to provide reliable and stable CHIRP sonar performance. It is specifically suited for vessels with a deadrise angle between 17 and 24 degrees. Made of stainless steel, it ensures increased durability and is compatible with various hull materials.

With which hull materials is the Garmin GT17M-THF 20° transducer compatible?

The GT17M-THF 20° transducer is compatible with fiberglass, wood, composite, aluminum, and steel hulls. For aluminum or steel hulls, it is mandatory to use the included galvanic isolation components to prevent galvanic corrosion and water ingress around the transducer.

What is the ideal deadrise angle for installing the GT17M-THF transducer at 20 degrees?

For optimal performance, the GT17M-THF 20-degree transducer is designed for vessels with a deadrise angle between 17 and 24 degrees at the installation point. It is critical to precisely measure the deadrise angle at the chosen location before drilling holes in the hull.

Does the GT17M-THF 20-degree transducer require professional installation?

Yes, installation of the GT17M-THF 20-degree transducer by a qualified marine installer is strongly recommended to ensure optimal performance and avoid any risk of injury, damage to the device, or damage to the vessel. Incorrect installation may result in damage or injury.

Which tools are required to install the Garmin GT17M-THF 20° transducer?

The main tools required for installation include:

A drill with a 3 mm (1/8 in) bitA hole saw of 98 mm (3 7/8 in) for fiberglass hulls or 101 mm (4 in) for metal hullsA 4.5 mm (3/16 in) Allen keyAn adjustable wrench suitable for nuts up to 108 mm (4 1/4 in)Marine sealant (flexible, fast-curing type, for below the waterline)Sandpaper and masking tapeAdditional elements may be required depending on hull type.

How to choose the best mounting location for the GT17M-THF 20° transducer on my boat?

For optimal performance, the transducer must be mounted in an area with clean, non-turbulent water flow. Consider the following:

On outboard and stern-drive boats, mount it forward and near the engine(s).On inboard boats, mount it forward and away from the propeller and propeller shaft.On stepped-hull boats, mount it forward of the first step.Avoid mounting it behind frames, struts, fittings, water intakes or discharges, or anything that could create air bubbles or turbulence.The transducer must be parallel to the bow-to-stern axis of your vessel.

Are specific precautions required when installing the GT17M-THF 20° depth sounder on a metal hull?

Yes, when installing the GT17M-THF 20° depth sounder on an aluminum or steel hull, it is mandatory to use the included galvanic isolation components. Failure to install them could lead to galvanic corrosion and potential water ingress around the transducer. Ensure the hull isolation gasket is flush with the inner hull surface.

Do I need to update the software on my Garmin chartplotter after installing this depth sounder?

Yes, you must update the software on your Garmin chartplotter when installing the GT17M-THF 20° depth sounder. For update instructions, refer to your chartplotter's user manual.
