Garmin Goes Deep with Ultra High-Definition Scanning Sonar
Garmin International says that its Ultra High-Definition scanning sonar uses a range of higher frequencies to deliver better images of fish and structure at greater depths. According to the manufacturer, the image detail level from this system is sharpened thanks to frequencies ranging from 0.8 to 1.2 MHz that reach down to 200 feet below the boat and put more sonar power on the targets and bottom structure.
The system includes Ultra High-Definition ClearVü and Ultra High-Definition SideVü sonar. The ClearVü version uses a downward-pointing transducer. The Ultra High-Definition SideVü offers a scrolling view of what’s passing to either side of the boat. Garmin says the system provides the greatest level of detail from its sonar systems to date, and that the new technology is compatible with the all GPSMAP and many ECHOMAP Plus multifunction displays.
The centerpiece of the Ultra High-Definition sonar system will be a GCV 20 sonar black box, and it will link to a GT34UHD transducer which will be available with both transom and trolling-motor mounts. The retail price is expected to be $599.99. The system will be compatible with the following Garmin systems:
- GPSMAP 8400/8600
- GPSMAP 7400/7600
- GPSMAP 10x2/12x2
- GPSMAP 12x2/12x2xsv Touch
- GPSMAP 7x2/9x2 series chartplotters
- 7-inch ECHOMAP Plus combo series
- 9-inch ECHOMAP Plus combo series
A through-hull transducer, the GT34UHD-TH, will also be available for a suggested retail price of $799.99 for a single transducer, while the GT34UHD-THP includes two transducers for $1,249.99. The GCV 20 will also allow the user to share data from Garmin’s Panoptix all-seeing sonar across multiple displays on the boat, by using the extra network expander.
