Garmin GT30-THP

“I upgraded to the Garmin GT56UHD and the clarity is unbelievable. You can literally see fish moving around structure. Hard Rig Marine helped me pick the right setup and it’s been spot on since day one.”
Michael R. — Cairns, QLD -
“I’m not a tech person, but the team made it super easy to install my GT54UHD transducer. Works perfectly with my ECHOMAP — I’ve never had sonar this clear in the estuary before!”
Jenny L. — Mandurah, WA -
“The Airmar B175M changed my whole deep drop setup. Way better definition and stability compared to my old transducer. You get what you pay for — and these guys know their stuff.”
Ben T. — Newcastle, NSW
GARMIN GT30-THP: ClearVü™ & SideVü™ Thru-Hull Pair (Up to 25° Deadrise)
The Garmin GT30-THP is a high-performance **thru-hull transducer pair** (Port and Starboard) designed for permanent installation on vessels with deadrise from **5 degrees to 25 degrees**. This pair features two stainless steel stem transducers that deliver **500 W per element** of scanning power across **CHIRP ClearVü™ and SideVü™ sonar**. It provides clear definition of objects and structure below and to each side of the boat, achieving superior SideVü range up to **500 feet** and ClearVü depth up to **750 feet**. It is optimized for pairing with black box sonar modules like the GCV™ 10.
THRU-HULL PAIR FOR MAXIMUM CLARITY
Installing a dedicated Port/Starboard transducer pair eliminates hull shadow interference, ensuring optimized performance for SideVü and stable returns, particularly on deep-V hulls.
KEY SONAR & INSTALLATION FEATURES
- Optimized Scanning: Provides dedicated **CHIRP 455 kHz and 800 kHz** scanning frequencies for clear definition of structure.
- Wide Deadrise Support: Includes fairing blocks and hardware specifically designed to compensate for hull deadrise angles between **5 and 25 degrees**.
- Total Power: 500 W per element, with a total potential power of 1,500 W.
- No Traditional Sonar: This is a dedicated scanning transducer kit and **does not** include traditional CHIRP functionality.
CONNECTIVITY AND DURABILITY
The GT30-THP uses durable stainless steel stems and simplifies the connection process via an included Y-cable.
- **12-Pin Connection:** The included Y-cable allows both transducers to consolidate and connect to a **single 12-pin port** on your Chartplotter or Black Box.
- **Durability:** Stainless steel stems provide long-term protection against corrosion.
Inverell Boating Centre Expert Note:
The GT30-THP is the premier permanent installation choice for maximizing scanning resolution on deep-V hulls (5° to 25° deadrise). It is a **scanning-only solution**—ideal when paired with a separate high-power Traditional CHIRP transducer (e.g., a GSD module or a Garmin single-frequency unit) for comprehensive coverage. **Professional installation is essential.**
