Garmin B744V 600W Triducer 50/200kHz - 8-Pin

Upgrade your boat's sonar system with a transducer that delivers crystal-clear underwater insights, whether you're chasing trophy fish in deep waters or navigating shallow coastal zones. This robust thru-hull model stands out by combining depth sounding, speed logging, and water temperature sensing into a single, streamlined package—eliminating the clutter of multiple sensors and simplifying your setup.

Superior Sonar Performance for Serious Boaters

Engineered for vessels with hull deadrises between 0 and 24 degrees, this transducer mounts seamlessly through the hull, providing reliable data even in choppy conditions. Its dual-frequency operation—50 kHz for wide-area scanning up to 1,200 feet and 200 kHz for precise, high-resolution imaging down to 800 feet—lets you adapt to any fishing or cruising scenario. The powerful 600-watt output ensures strong signal returns, cutting through thermoclines and minimizing interference from boat noise or aerated water.

Boaters rave about the accuracy of its speed-through-water readings, which help optimize fuel efficiency and plan safe passages. Paired with the included temperature probe, you'll track baitfish movements tied to thermal layers, giving you an edge on the water.

Built Tough for Marine Environments

Crafted from corrosion-resistant bronze, this unit thrives in saltwater exposure, shrugging off the harshest conditions year after year. The 39-foot cable offers ample reach for clean routing to your display unit, reducing signal loss and easing professional or DIY installs. Its streamlined fairing design minimizes drag, preserving your boat's speed and handling without compromising hydrodynamics.

• Wide Coverage: 45-degree beam at 50 kHz for searching large areas; tight 12-degree beam at 200 kHz for targeting structure and fish.
• Deep Water Capability: Probe depths from 800 to 1,200 feet, ideal for offshore adventures.
• All-in-One Design: Depth, speed, and temp in one thru-hull mount—no extra holes or wiring hassles.
• Versatile Fit: 2-inch shaft suits most hull thicknesses; supports deadrise angles common on planing hulls.

Streamlined Installation for Quick Results

Getting this transducer up and running doesn't require a marine yard overhaul. Start by selecting a flat hull section forward of the prop, away from strakes or intakes to avoid turbulence. Drill precisely, bed in sealant for a watertight seal, and fair the block to match your hull's curve. Route the 8-pin cable through existing conduits if possible, securing it against chafe. Detailed instructions guide you through calibration, ensuring speed and depth readings align perfectly with your GPS and chartplotter.

Pro tip: Test in shallow water post-install to verify bubble-free operation and fine-tune gain settings for your local conditions. This setup delivers immediate improvements in bottom tracking and fish arch definition.

Real-World Advantages Over Basic Transducers

Unlike flush-mount or transom alternatives, this thru-hull design sits lower in the water column, capturing cleaner signals unaffected by hull slap or prop wash. Anglers targeting wrecks or reefs appreciate the triducer's speed data for drift calculations, while cruisers rely on temp trends for weather insights. It's a step up from single-frequency units, offering flexibility without the complexity of networkable sensors.

For trailered boats, its durability means worry-free storage, and the bronze construction holds value for resale. Invest in precision that enhances every outing, from weekend spins to multi-day charters.
