Garmin GT30-THP SS Thru-Hull Pair DownVü/SideVü Scanning Transducer w/Temp f/Hull Deadrises 5°-25°

The Garmin GT30-THP SS Thru-Hull Pair DownVü/SideVü Scanning Transducer with Temperature capability is purpose-built for anglers and boaters who demand the most detailed underwater intelligence available. This stainless steel thru-hull transducer pair delivers dual-frequency sonar imaging that transforms how you read structure, locate fish, and navigate your fishing grounds.

The GT30-THP SS features Garmin's advanced DownVü and SideVü imaging technologies, which paint high-resolution sonar pictures of the water column directly below and to the sides of your boat. DownVü works like a downward-facing camera, revealing bottom contour, vegetation, and fish suspended at any depth, while SideVü extends your sonar awareness laterally. The thru-hull design integrates seamlessly into your hull with deadrise angles from 5° to 25°, accommodating most modern fiberglass boats.

Professional and serious recreational anglers benefit most from this system, particularly those fishing larger water bodies where conventional sonar may fall short. Built in stainless steel, this transducer resists saltwater corrosion and handles years of constant operation, while integrated temperature sensing provides real-time water data for seasonal pattern fishing.
