Raymarine E26030 Thru-Hull Depth Transducer - Retractable
Raymarine E26030 Thru-Hull Depth Transducer - Retractable — Product description
Enhance your boating experience with the Raymarine thru-hull depth transducer designed for precision and reliability on the water. This retractable model mounts seamlessly through your hull, delivering accurate depth readings even in challenging conditions. Ideal for sailors and powerboaters who demand dependable sonar performance from their Raymarine instruments, it features a low-profile design that minimizes drag while offering the flexibility to retract the shaft for safe trailering or beaching.
Key Features and Performance
Crafted from durable plastic, this transducer operates at 200 kHz with a powerful 250-watt output and a focused 12-degree beam angle. The narrow beam provides crisp, targeted bottom detection, helping you navigate shallow waters, spot fish structure, or avoid underwater hazards with confidence. Its 2-foot retractable shaft protects the ceramic element during retraction, extending the unit's lifespan in rugged marine environments.
- Retractable design for easy protection and maintenance
- Low-profile housing reduces water resistance
- 45-foot cable with spade connectors for straightforward wiring
- Suited for aluminum and fiberglass hulls up to moderate speeds
Unlike fixed thru-hull options, the retractable mechanism lets you lift the transducer out of the water quickly, preventing damage from debris or when hauling your vessel.
Seamless Integration with Raymarine Instruments
This depth sensor pairs effortlessly with popular Raymarine displays, ensuring plug-and-play simplicity. Connect it to unlock real-time depth data overlaid on charts or standalone instruments.
- ST60+ series for compact, no-fuss installations
- ST290 for advanced ultra-precision systems
- ST70 instruments (requires separate Depth Pod for full compatibility)
- Works with ST40 and other ST60/290 variants via standard spade lugs
Whether upgrading an older setup or building a new one, this transducer maintains Raymarine's reputation for robust NMEA compatibility and reliable signal processing.
Installation Tips for Optimal Results
Installing a thru-hull transducer demands care to ensure peak performance. Start by selecting a hull location forward of the propeller and keel, in relatively flat water flow, typically 1/3 of the hull length from the bow. Drill a precise 2-inch hole, seal with marine-grade sealant, and bed the housing firmly against the hull interior.
- Clean and fair the hull exterior for flush mounting
- Route the 45-foot cable away from noise sources like engines or bilge pumps
- Secure the retraction mechanism for easy access
- Test in water before finalizing to calibrate beam alignment
For best accuracy, angle the transducer face parallel to the waterline when your boat is loaded and floating. This setup minimizes air entrainment and maximizes bottom-lock readings.
Long-Term Reliability and Care
Built to withstand saltwater exposure, this plastic transducer resists fouling better than some metal alternatives. Regular maintenance keeps it performing like new: Wipe the face monthly with a soft cloth and mild soap, inspect the O-rings on the retraction shaft annually, and retract during winter storage. In high-growth areas, apply a thin anti-fouling paint layer approved for transducers to maintain sensitivity.
Boaters report years of trouble-free service, praising its consistent depth updates in currents up to 10 knots and depths beyond 700 feet, depending on conditions.
Frequently Asked Questions
What hull types is this Raymarine depth transducer compatible with?
It works best with aluminum and fiberglass hulls. Avoid wood or steel hulls, as they can interfere with signal transmission.
Does the retractable feature make installation harder?
No, the design simplifies protection without complicating the install. The 2-inch hole size is standard, and retraction access is straightforward from inside the hull.
What is the beam angle and how does it affect readings?
The 12-degree beam offers precise, narrow coverage ideal for detailed bottom contouring and fish finding, rather than wide-area scanning.
Can I use this with newer Raymarine multifunction displays?
It's optimized for ST-series instruments. For Axiom or Element series, consider adapters or newer transducers for full integration.
How do I clean and maintain the transducer face?
Gently clean with fresh water and a soft brush after each trip. For stubborn growth, use a plastic scraper—never metal—to avoid scratching the ceramic.
What cable length is included and can it be extended?
A 45-foot cable comes standard with spade connectors. Extensions are possible using Raymarine-compatible marine cable to minimize signal loss.
Is this transducer suitable for high-speed boating?
It's rated for hull speeds up to 12 knots comfortably. At higher speeds, cavitation may affect accuracy; opt for flush-mount models for planing hulls.
