Garmin Ultra High-Definition Scanning Sonar

Garmin has announced its introduction of a new Ultra High-Definition scanning sonar, which uses a higher frequency range to deliver super-clear images and detail of structure and fish below and around the boat at greater depths. The new system includes Ultra High-Definition ClearVü and Ultra High-Definition SideVü sonar with frequencies ranging from .8 to 1.2 MHz. ClearVü image clarity lets anglers detect fish and bottom features to 200 feet below the boat.

The Ultra High-Definition scanning sonar is available as a stand-alone system that’s compatible with all of Garmin’s current GPSMAP and select ECHOMAP Plus multi-function displays.

Scanning sonar is redefined with Ultra High-Definition as it delivers greater resolution by putting more power on the targets with a higher frequency range than before. To see what’s below the boat, Ultra High-Definition ClearVü scans with a downward-facing element that provides clear images at depths of up to 200 feet. For a detailed look at what’s around the boat, Ultra-High Definition SideVü shows clear images of structure and fish on both sides of the boat. Imagery from the Ultra High-Definition system can be shared seamlessly across multiple networked displays so anglers can easily see the information they need at a glance from different locations on the boat based on preference or the fishing situation. Using the included extra network expander on the GCV 20 sonar black box, Panoptix all-seeing sonar can also be distributed to multiple networked displays.

It’s compatible with the GPSMAP 8400/8600, GPSMAP 7400/7600, GPSMAP 10×2/12×2, GPSMAP 12×2/12x2xsv Touch and GPSMAP 7×2/9×2 series chartplotters, and the 7″ and 9″ ECHOMAP Plus combo series.


Ultra High-Definition system w/ networkable GCV 20 sonar black box, GT34UHD transducer and both transom and trolling motor mounts: $600

GT34UHD-TH (through-hull): $800 (single transducer)

GT34UHD-THP (through-hull): $1,250 (2 transducers)
