Engineered for serious shallow-water anglers, the Garmin GT30-THP Thru Hull Pair Scanning Transducer delivers crystal-clear CHIRP ClearVü and CHIRP SideVü scanning beneath and to the sides of your hull, helping you spot structure, targets, and moving fish with confidence.
-
Through-hull CHIRP scanning: ClearVü below the hull and SideVü to the sides for comprehensive underwater visibility.
-
Stainless steel stems: Durable construction with reliable alignment in demanding conditions.
-
Depth, speed, and temperature sensors: Built-in sensors provide real-time context for navigation and fishing decisions.
-
High power: 500 W per element (1,500 W total) for strong, crisp returns in shallow to mid-depth water.
-
Deep scanning capability: ClearVü up to 750 ft; SideVü up to 500 ft to each side.
-
CHIRP frequencies: 455 kHz (425–485 kHz) and 800 kHz (790–850 kHz) for enhanced target separation.
-
Beam patterns: ClearVü 1.4°x53° @ 455 kHz; 0.8°x30° @ 800 kHz; SideVü 1.1°x53° @ 455 kHz; 0.7°x30° @ 800 kHz.
-
Deadrise compatibility: Supports hull deadrises up to 25° for a wide range of boats.
-
GCV 10 integration: Designed to pair with Garmin GCV 10 scanning sonar module for a complete sonar solution.
-
What’s included: 12-pin port and starboard transducers with stainless steel stems, isolation bushings, fairing blocks, Y-cable, mounting hardware, and installation instructions.
-
Cable length: 5 ft + 30 ft Y-extension cable.
-
Number of pins: 12-pin.
The GT30-THP pair delivers a detailed, reliable view of the underwater world, enabling you to identify structure, schools, and individual fish with confidence in shallow and mid-depth water. Built-in depth, speed, and temperature sensors provide immediate context for smarter navigation and fishing decisions. With a robust thru-hull design, durable stems, and broad deadrise compatibility, this transducer setup suits a wide range of boats, and when paired with the GCV-10 module, offers a complete, high-performance scanning sonar solution.
