Detailed description

Prečna sonda Garmin GT17M-THF 20° je zasnovana za zagotavljanje zanesljivih in stabilnih sonarnih zmogljivosti CHIRP, posebno prilagojena plovilom z zakrivljenostjo dna (deadrise) med 17 in 24 stopinjami. Izdelana iz nerjavnega jekla, sonda zagotavlja povečano trajnost in razširjeno združljivost z različnimi materiali trupa, vključno s steklenim vlaknom, lesom, kompoziti, aluminijem in jeklom.

Namestitev in združljivost materialov trupa

Namestitev sonde GT17M-THF zahteva posebno pozornost glede materiala trupa. Za trupe iz aluminija ali jekla je uporaba vključenih komponent za galvansko izolacijo obvezna, da se prepreči galvanska korozija in vdor vode okoli sonde. Ta zahteva poudarja premišljeno zasnovo Garmin za varno in trajno integracijo, v nasprotju s preprostimi sondami, ki morda ne nudijo take bistvene zaščite na kovinskih trupih. Namestitev se priporoča izvedeti usposobljenem mornarskem strokovnjaku, da se zagotovi optimalna zmogljivost in prepreči morebitna škoda.

Optimizacija zmogljivosti in pozicioniranje

Model GT17M-THF 20° se od verzij 0° ali 12° razlikuje po sposobnosti natančnega kompenziranja specifičnega kota zakrivljenosti dna, kar zagotavlja, da je transduktor pravilno usmerjen proti dnu za maksimalno detekcijo. Za trupe iz steklenega vlakna je potrebna luknja premera 98 mm, medtem ko kovinski trupi zahtevajo luknjo premera 101 mm. Sondo je treba namestiti v območju čiste vode, brez turbulenc, ki jih ustvarjajo vijaki, kobilice, vdori vode ali druga oprema. Optimalno pozicioniranje je ključno: pred motorjem za motorje z zunanje nameščenim motorjem, daleč od vijaka za motorje z notranjim nameščenim motorjem ali med motorji za dvomotorna plovila. Po namestitvi je potrebna posodobitev programske opreme kartnega risala Garmin za zagotovitev združljivosti in maksimalnih zmogljivosti. Redno vzdrževanje z vodno protiobalno barvo in čiščenje brez agresivnih topil podaljšuje življenjsko dobo 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 integration of galvanic isolation components for metal hulls (aluminum, steel) is a major technical advantage, ensuring effective protection against corrosion and lasting watertightness—a critical point 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’s 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 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 20-degree transducer?

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 crucial 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 can lead to 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-degree transducer on my boat?

For optimal performance, the transducer must be mounted in an area of clean, non-turbulent water. 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, stringers, fittings, water intakes or discharges, or anything that could create air bubbles or turbulence.The transducer must be parallel to the fore-aft axis of your vessel.

Are special precautions required when installing the GT17M-THF 20-degree transducer on a metal hull?

Yes, when installing the GT17M-THF 20-degree transducer on an aluminum or steel hull, it is imperative to use the included galvanic isolation components. Failure to install them could lead to galvanic corrosion and potential water ingress around the transducer. You must also ensure the housing isolator 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.
