Installation and choosing accessories

Match transducer, frekvenser, stik, skroghældning og display. Et kompatibelt stik alene sikrer ikke alle funktioner.

Installation og kompatibilitet

Kontrollér transducertype, stik, frekvens, effekt, skrogmateriale, deadrise og monteringsform. Placeringen skal give transduceren så rent vandflow som muligt og passe til den kompatible Garmin-enhed.

💡 Mit råd før bestilling

Jeg anbefaler, at model, strøm, stik og monteringsforhold bliver kontrolleret, før Garmin GT21-TH bestilles. Du er velkommen til at sende billeder og modelnumre, så hjælper jeg med vurderingen.

Full product description

Garmin GT21-TH – developed for life on board

With the Garmin GT21-TH, you get sonar or transducer equipment for displaying depth, bottom, fish, and structure under the boat. It is an obvious choice when the equipment needs to function as a well-integrated part of the boat's overall installation, and you want to ensure compatibility, mounting, and practical use on board.

⚡ Advantages in practice

  • Match the pin count on the sonar port of your sounder
  • 77/200 kHz sonar transmits a single ping at either 77 or 200 kHz
  • 260/455 kHz ClearVü is ideal for deeper water, 1000' max depth scanning sonar
  • Can provide a more detailed image of bottom conditions and underwater objects depending on the technology chosen.
  • Can be included in a compatible Garmin sonar system together with a plotter or black box.
  • The correct choice depends on connector type, frequency, power, hull, and the desired mounting method.

⛵ Suitable for

  • Fishing, depth measurement, and a better understanding of bottom conditions
  • New Garmin sonar installations and upgrades
  • Boat owners who want help with transducer, frequency, connector, and mounting

📦 Contents of the package

  • Hull mounts: These are attached to the rear (transom) of a boat hull. Alternatively, you can use the included equipment to install on a trolling motor.

🔧 Installation and compatibility

Check transducer type, connector, frequency, power, hull material, deadrise, and mounting method. The placement must provide the transducer with as clean a water flow as possible and match the compatible Garmin device.
