Garmin B619 12° Bronze Thru Hull Transducer - 8-Pin

Discover Superior Performance with the Garmin B619 Bronze Thru-Hull Transducer

Upgrade your boating experience with this robust 12° tilted element thru-hull transducer designed for precision and reliability on the water. Crafted from durable bronze, it delivers crystal-clear depth readings and temperature data, even at higher speeds, making it a go-to choice for serious anglers and cruisers alike. Its low-profile design hugs the hull closely, reducing drag while maximizing sonar accuracy across a range of boat types.

Engineered for Optimal Sonar Coverage

The tilted ceramic element compensates for hull deadrise angles between 8° and 16°, ensuring a vertical beam that captures detailed echoes without the need for additional fairings. Operating at dual frequencies of 77 kHz and 200 kHz, it offers versatile beam widths—45° on low frequency for wide-area scanning and 15° on high for pinpoint targeting. With a 500-watt power rating, you can probe depths up to 900 feet, ideal for offshore adventures or deep-water fishing.

• Dual-Frequency Operation: 77/200 kHz for broad and focused coverage
• Impressive Depth Capability: Reliable readings to 900 feet
• Power Output: 500 watts for strong signal penetration
• Beam Widths: 45°/15° (-3dB) for varied scanning needs
• Cable Specs: 30-foot length with right-angle exit for clean routing and protection
• Mounting Flexibility: Thru-hull with 2-inch shaft, includes rubber washer for uneven surfaces

Why Boaters Trust This Bronze Design

Bronze construction stands up to saltwater corrosion, thriving in fiberglass or wooden hulls on powerboats and sailboats up to 30 feet. The nearly flush mount protrudes just 5mm beyond the hull, minimizing turbulence that could distort readings at speed. Anglers appreciate the integrated temperature sensor for spotting thermoclines, while cruisers value consistent performance from coastal runs to open water. Paired with compatible Garmin chartplotters and sounders via its 8-pin connector, it unlocks sharper fish arches and bottom contours for safer navigation and bigger catches.

Streamlined Installation for DIY Enthusiasts

Setting up is straightforward with included instructions and hardware. Drill a precise hole matching the 2-inch shaft, secure with the hull nut, and route the cable through existing conduits. The 12° built-in tilt handles moderate deadrise angles out of the box—no extra adjustments needed. For best results, fair the hull surface if possible, apply marine sealant around the thru-hull, and test in shallow water before heading out. This setup complies with ABYC H-27 standards, giving you peace of mind on every trip.

Real-World Applications and Tips

Whether chasing trophy fish in deep channels or monitoring water temps for optimal trolling speeds, this transducer shines. On sailboats, its drag-free profile won't slow you down during heel, and powerboat owners love how it maintains lock at planing speeds. Pro tip: Pair it with Garmin's LiveScope or traditional CHIRP for enhanced clarity, and regularly inspect the face for marine growth to keep signals crisp. Boat size up to 30 feet? This is your match.
