Detailed FAQ Section

What does the GT54 transducer include?

The GT54-TM transducer is a premium sonar accessory included with the Garmin ECHOMAP UHD2 63sv. It supports traditional CHIRP, ClearVü, and SideVü sonar frequencies, offering a complete view of the water column and structure beneath and to the sides of your boat. The transducer is easy to mount on the transom or trolling motor and is durable enough for freshwater and light saltwater use.

This multi-frequency transducer provides near-photographic views down to 800 feet, depending on conditions. It’s a favorite among anglers targeting fish-holding structures or mapping new waters.

Can I use this unit in saltwater?

Yes, the ECHOMAP UHD2 63sv can be used in saltwater; however, the preloaded GN+ maps are focused on U.S. lakes and rivers. For coastal or offshore use, you’ll need to purchase compatible BlueChart g3 coastal maps. Additionally, rinse the unit and transducer with fresh water after each saltwater outing to prevent corrosion.

Ensure all NMEA connectors are sealed and install a corrosion-resistant mounting bracket if you plan to use it in brackish or marine conditions frequently.
