    “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!”

    “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.”

    GARMIN GT23M-TH: Mid-Band CHIRP & ClearVü™ Thru-Hull Transducer (600W/500W)

    The Garmin GT23M-TH is a dedicated, high-power **thru-hull transducer** designed for permanent installation on coastal and offshore vessels. Featuring a durable stainless steel stem, it delivers **600 W Mid-Band CHIRP Traditional Sonar** and **500 W CHIRP ClearVü™ scanning sonar**. This unit is optimized for rough sea conditions and provides reliable, deep-water traditional sonar down to **1,800 feet** and clear structure definition down to **1,000 feet**.


    THRU-HULL DURABILITY & DEEPWATER POWER

    The GT23M-TH ensures superior performance and stability at speed, while the Mid-Band CHIRP (80–160 kHz) is excellent for deep-water tracking and noise reduction.

    KEY SONAR & INSTALLATION FEATURES

    • High-Power Traditional Sonar: 600 W Mid-Band CHIRP for depth capability up to **1,800 feet**.
    • CHIRP ClearVü™ Scanning: 500 W scanning power (260/455 kHz) for clear structure definition down to **1,000 feet**.
    • Deadrise Compatibility: Includes installation hardware designed for hulls with deadrise angles up to **25 degrees**.
    • Durable Construction: Stainless steel stem for maximum protection and durability beneath the waterline.

    CONNECTIVITY AND INTEGRATION

    The GT23M-TH uses the reliable 8-pin connection and includes a long cable for integration on larger vessels.

    • **8-Pin Connector:** Uses the 8-pin connector for simultaneous output of Traditional and ClearVü sonar signals.
    • **Cable Length:** Includes a robust **30-foot cable** for flexible routing.

    Inverell Boating Centre Expert Note:

    The GT23M-TH is the ideal transducer for customers upgrading their vessel with a permanent, high-power solution. The 600W traditional sonar paired with 500W ClearVü ensures excellent coverage for mid-range depths. Due to the requirement for hull penetration and compensation, **professional marine installation is highly recommended**.

    • “I run dual Garmin units and the thru-hull transducer from Hard Rig gives me crystal bottom lock even at 25 knots. Couldn’t be happier with the setup and advice.”

      Shaun K. — Townsville, QLD

    • “I was worried about installing a thru-hull model, but the support from Hard Rig was awesome. The Airmar B60 works flawlessly on my fibreglass hull — depth readings are spot on.”

      Emily P. — Hobart, TAS

    • “Just fitted a GT15M-TM to my tinnie and I’m blown away by the detail. Picks up structure I never knew was there. Shipping was fast and everything came ready to install.”
