Discover the precision and reliability that serious boaters demand with this low-profile plastic thru-hull depth transducer. Designed for seamless integration into wood or fiberglass hulls, it delivers accurate depth readings even in challenging marine conditions. Whether you're navigating shallow coastal waters or tracking bottom structure during offshore adventures, this transducer stands out for its rugged construction and straightforward performance.

Engineered for Superior Depth Detection

Crafted with a sleek low-profile design, this transducer minimizes drag and reduces vulnerability to underwater obstacles, making it ideal for vessels operating in rough seas or debris-filled waters. Its dual-frequency capability—operating at 50 kHz and 200 kHz—provides versatility: the wider 45-degree beam at 50 kHz excels for broad coverage in deep water, while the narrower 12-degree beam at 200 kHz sharpens focus for detailed shallow-water scans. Supporting hull deadrises from 0 to 8 degrees, it ensures optimal beam projection without extensive adjustments.

Backed by a power rating of 600 watts, it punches through thermoclines and suspended particulates, offering clear, dependable data to your compatible Raymarine echo sounder. The included 30-foot cable with connector simplifies routing through tight bilge spaces, getting you on the water faster.

Real-World Performance and Durability

Boaters praise its ability to maintain consistent readings across varying speeds and sea states. In tournaments or long-range cruises, it helps spot wrecks, ledges, and bait schools by delivering noise-free returns. The plastic housing withstands corrosion from saltwater exposure, and its thru-hull mounting creates a flush, hydrodynamic profile that won't snag lines or foul gear.

• Versatile Beam Options: Switch between wide-area scanning and pinpoint precision on the fly.
• Robust Build: Engineered to endure impacts, UV degradation, and extreme temperatures.
• Easy Integration: Pairs effortlessly with legacy and select modern sounder modules for hassle-free upgrades.

Installation Insights for Peak Results

Mounting this transducer is straightforward but rewards attention to detail. Select a location forward of the propellers, at least one-third of the hull length from the stern, to avoid turbulence. Fair the housing to match your hull's deadrise using marine sealant for a watertight bond. For fiberglass hulls, drill a precise hole and bed it in place; wood hulls may require additional sealing around the thru-hull fitting. Test at idle and planing speeds to fine-tune the angle—aim for the beam to strike the seabed perpendicularly at your typical cruising velocity.

Pro tip: In colder climates, consider anti-freeze flushing lines if winterizing, though the plastic construction resists cracking better than metals. Regular hull cleaning prevents marine growth from attenuating signals.

Why It Excels for Everyday Boating

Unlike bulkier alternatives, its low silhouette hugs the hull, preserving your boat's lines and performance. Cruisers appreciate the fuel efficiency gains from reduced resistance, while anglers value the reliable bottom lock for marking hot spots. It's a workhorse that quietly enhances safety by alerting to sudden depth changes, giving you confidence from dock to horizon.
