    “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.”

    AIRMAR® B258: Deep-Water Traditional Thru-Hull Transducer (1 kW)

    The AIRMAR® B258 is a high-power, mid-range **thru-hull transducer** designed for serious deep-water sport fishing. This 8-pin unit features robust **1 kW Traditional Sonar** operating at **50/200 kHz** dual frequencies. It delivers reliable depth returns between **1,500 and 2,200 feet (457–670 meters)**, with a narrow beam optimized for excellent bottom definition and target separation in deep water. It supports a wide deadrise range, from **0 to 26 degrees**.


    1 KW POWER & NARROW BEAM FOCUS

    The B258 utilizes its powerful transmission to punch through deep water, providing focused returns for precise target identification.

    KEY SONAR & PERFORMANCE FEATURES

    • Deep Penetration: **1 kW power output** (50/200 kHz) for reliable depth tracking between **1,500 and 2,200 ft**.
    • Narrow Beam Focus: Features specialized beamwidths (14°x23° at 50 kHz, 3°x5° at 200 kHz) for superior bottom definition and target separation in deep columns.
    • Wide Deadrise Support: Thru-hull installation is configurable for deadrise angles up to **26 degrees**.
    • Housing: Durable construction performs well at high speeds.

    CONNECTIVITY AND INTEGRATION

    The B258 is a high-power, bronze thru-hull sensor compatible with a wide range of Garmin systems.

    • **8-Pin Connector:** Uses the 8-pin connector for power and traditional sonar data output.
    • **Cable Length:** Includes a robust **39-foot cable** for flexible routing.
    • **Compatibility Note:** Requires a compatible Garmin Chartplotter that supports 1 kW, 50/200 kHz traditional sonar.

    Inverell Boating Centre Expert Note:

    The AIRMAR B258 is a dedicated 1 kW Traditional Sonar unit (no scanning capability). This is a heavy-duty option focused on deep-water penetration (50 kHz) and accurate shallow-water detail (200 kHz). **It requires a fairing block** for deadrise correction and **professional installation is essential**.
