Detailed description

Probušna sonda Garmin GT17M-THF 20 stupnjeva osmišljena je za pouzdane i stabilne performanse sonara CHIRP, posebno prilagođena brodovima s kutom dna (deadrise) između 17 i 24 stupnja. Izrađena od nehrđajućeg čelika, ova sonda osigurava povećanu trajnost i proširenu kompatibilnost s različitim materijalima trupa, uključujući stakloplastiku, drvo, kompozite, aluminij i čelik.

Ugradnja i kompatibilnost materijala trupa

Ugradnja sonde GT17M-THF zahtijeva posebnu pažnju pri odabiru materijala trupa. Za trupe od aluminija ili čelika obavezna je upotreba uključene komponenata za galvansku izolaciju kako bi se spriječila galvanska korozija i prodori vode oko sonde. Ovaj zahtjev naglašava razmišljanje tvrtke Garmin o sigurnoj i trajnoj integraciji, za razliku od jednostavnijih sondi koje možda neće pružiti ovaj bitan zaštitni mehanizam na metalnim trupovima. Preporučuje se ugradnja od strane kvalificiranog pomorskog tehničara kako bi se osigurale optimalne performanse i spriječila eventualna oštećenja.

Optimizacija performansi i pozicioniranje

Model GT17M-THF 20 stupnjeva razlikuje se od verzija s 0 ili 12 stupnjeva po svojoj sposobnosti precizne kompenzacije specifičnog kuta dna, osiguravajući da je pretvornik pravilno orijentiran prema dnu za maksimalno otkrivanje. Za trupe od stakloplastike potreban je otvor promjera 98 mm, dok metalni trupovi zahtijevaju otvor od 101 mm. Sonda se mora ugraditi u području čiste vode, bez turbulencija uzrokovanih brodskim vijcima, kobilicama, usisnim otvorima ili drugim uređajima. Optimalno pozicioniranje je ključno: ispred motora za vanbrodske motore, daleko od brodskog vijka za unutarnje motore, ili između motora za dvomotorne sustave. Nakon ugradnje potrebno je ažuriranje softvera karte Garmin kako bi se osigurala kompatibilnost i maksimalne performanse. Redovito održavanje s protupriraslim bojama na bazi vode i čišćenje bez agresivnih otapala produljit će vijek trajanja sonde.

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

The Garmin GT17M-THF 20-degree transducer is a high-quality through-hull transducer 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 watertightness—a critical feature often overlooked in less specialized equipment.

This model is specifically calibrated for deadrise angles of 17 to 24 degrees, making it a precise choice for hulls with this geometry. Installation must comply with Garmin guidelines, including the use of marine sealant and proper orientation (arrow pointing toward the keel), to fully leverage its capabilities. While installation requires hull drilling (98 mm for fiberglass, 101 mm for metal) and 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 water flow zone. The requirement for chartplotter software updates 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 deliver 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 enhanced durability and is compatible with various hull materials.

With which hull material types 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 measure the deadrise angle precisely 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 the 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 close to the engine(s).On inboard boats, mount it forward and away from the propeller and propeller shaft.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 special precautions required when installing the GT17M-THF 20-degree depth sounder on a metal hull?

Yes, when installing the GT17M-THF 20-degree 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 boot 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-degree depth sounder. For update instructions, refer to your chartplotter's user manual.
