The TM260 comes with a rugged stainless-steel mounting bracket that is easy to install and has a streamlined shape. The performance of Airmar's "1 kW, 260 family" of transducers is legendary. The combination of power and sensitivity has made this the high-performing transducer of choice with conventional fishfinders. Operating at 50 and 200 kHz, the narrow, 6° beam at 200 kHz provides excellent target resolution and crisp images of fish holding tight to wrecks and reefs. The 50 kHz is excellent at deep-water detection, and the wide, 19° beam yields broad coverage under the boat.

Discover Superior Depth and Temperature Sensing

Upgrade your boating experience with this reliable plastic transom mount transducer designed for precise depth readings and accurate water temperature monitoring. Ideal for anglers and recreational boaters who demand clear underwater visibility without the hassle of through-hull installations, it delivers consistent performance across various water conditions.

Whether you're chasing trophy fish in deep offshore waters or navigating shallow coastal areas, this unit stands out for its rugged build and high-power output, ensuring you never miss a structure or thermocline.

Standout Features for Everyday Boating

• Dual-Frequency Operation: Seamlessly switch between wider coverage at lower frequencies for broad scans and sharper details at higher ones for pinpoint accuracy.
• High-Power Handling: Built to push through challenging environments, offering reliable signals even in deeper waters or choppy seas.
• Integrated Temperature Sensor: Track water temp changes in real-time to identify baitfish hotspots and productive fishing zones.
• Flexible Mounting: Adapts to transom angles from gentle slopes to steeper inclines, making it versatile for different hull designs.
• Plastic Construction: Corrosion-resistant and lightweight, perfect for long-term exposure to saltwater without compromising durability.

Real-World Performance That Delivers

In practical use, this transducer excels at separating bottom details from bait schools, thanks to its optimized beam patterns. The wider beam sweeps larger areas efficiently during trolling or searching, while the narrower beam hones in on wrecks and drop-offs with exceptional clarity. Boaters report crisp readings down to significant depths, even when running at higher speeds, minimizing signal loss from air bubbles or debris.

For temperature tracking, it provides quick response times, helping you adjust lures or baits based on subtle shifts that influence fish behavior. It's a game-changer for live-lining or jigging, where knowing the exact conditions below the surface gives you the edge.

Effortless Installation for Quick Setup

Mounting is straightforward on most outboard or sterndrive boats. Position it just off the transom's deadrise, ensuring the trailing edge sits slightly lower to avoid cavitation. Use marine-grade sealant around screw holes for a watertight fit, and route the cable away from engine interference to prevent noise. Most setups take under an hour, getting you back on the water fast.

Pro tip: Pair it with a compatible display unit for instant plug-and-play integration, and always test in shallow water before heading out to calibrate your system.

Seamless Integration with Your Gear

This 8-pin model connects effortlessly to a range of marine electronics, supporting high-definition sonar views and CHIRP capabilities when matched right. It's a solid match for mid-to-high-end units focused on fishing features, enhancing your screen with vivid fish arches and contour maps.

Keep It Performing Like New

Routine care extends its lifespan: Rinse with fresh water after saltwater trips, inspect the face for marine growth, and store it dry during off-seasons. Avoid high-pressure washes directly on the ceramic element to prevent micro-cracks. With proper upkeep, expect years of trouble-free service.
