Garmin Airmar SS502 Stainless Steel Depth & Temp 600W, 50/200kHz Transducer - 8 Pin

Discover Superior Underwater Performance with the SS502 Transducer

Engineered for marine enthusiasts who demand precision and durability, this stainless steel thru-hull transducer stands out in challenging marine environments. Its impact-resistant design thrives on planing hull powerboats and displacement vessels alike, delivering reliable depth readings and water temperature data even in rough conditions. Whether you're navigating shallow bays or probing deep offshore waters, its dual-frequency capability ensures crystal-clear sonar returns tailored to your needs.

Crafted from robust 316 stainless steel, it resists corrosion from saltwater exposure, making it a long-term investment for serious boaters. The stem mount allows for a clean, low-profile installation that minimizes drag, optimizing your vessel's hydrodynamics without compromising signal quality.

Key Features That Set It Apart

• Dual-Frequency Operation: Switch seamlessly between 50 kHz for deep-water bottom tracking—reaching impressive depths with wide coverage—and 200 kHz for sharp, detailed imaging in shallower zones, perfect for structure hunting or wreck identification.
• High-Power Output: 600W RMS power punches through thermoclines and murky water, providing consistent performance where lesser units falter.
• Integrated Temperature Sensor: Real-time water temp readings help you locate baitfish schools or monitor conditions for optimal trolling speeds.
• 8-Pin Connectivity: Plug-and-play with a wide array of compatible marine electronics, ensuring quick setup and hassle-free operation.
• Narrow Beam Precision: The 200 kHz element's focused beam reveals fine details like fish size, bottom composition, and subtle contours that broader beams miss.

Why Boaters Trust This Transducer for Real-World Results

In my experience working with marine electronics, transducers like this one excel where others wear out. The stainless steel construction shrugs off repeated impacts from debris or docking mishaps, while the high-performance fairing—strongly recommended for all setups—channels water flow smoothly over the face, eliminating air bubbles and turbulence that plague subpar installations.

For offshore anglers, the 50 kHz mode locks onto distant structure with ease, often spotting wrecks or drop-offs before they appear on charts. Inland lake fishers appreciate the 200 kHz detail for pinpointing brush piles or schooling crappie. Pair it with advanced CHIRP capabilities on modern sounders, and you'll unlock even richer data layers, from bait balls to individual game fish arches.

Unlike plastic alternatives that crack under UV or flex in heavy seas, this unit's rigidity maintains beam integrity, ensuring your sonar screen stays alive with actionable intel trip after trip.

Installation Insights for Peak Performance

Mounting a thru-hull transducer correctly is crucial—position it forward of the prop and keel, at least 1/4 hull below the waterline at rest. Dead-rise angles up to 24 degrees are no issue, but always bed it with marine sealant for a watertight seal. Pro tip: Align the transducer face vertically using a mounting pole; misalignment can skew readings by 20% or more.

For high-speed planing hulls, that optional fairing isn't just nice—it's essential. It streamlines flow, boosting high-speed accuracy and reducing noise. Test in various speeds and depths post-install to fine-tune your gains.

Compatibility and Versatility Across Hull Types

This versatile performer integrates smoothly with popular chartplotter brands, supporting everything from basic fishfinders to multifunction displays. It's ideal for fiberglass, wood, or metal hulls, adapting to V-hulls, deep-Vs, and multihulls. Saltwater pros love its toughness; freshwater users rave about the temp sensor's role in ice fishing or bass tournaments.

Maintenance Tips to Maximize Longevity

Keep it performing like new with simple care: Rinse with fresh water after every saltwater outing to flush salt crystals. Inspect the face annually for marine growth— a soft brush and eco-friendly cleaner do the trick. Avoid high-pressure washers that could etch the ceramic element. Stored ashore? Cover it to shield from UV degradation.
