Upgrade your fishing setup with the Garmin GT36-TM and GT15M-IH transducer bundle, designed for serious coastal and offshore anglers chasing bigger catches. This powerful combo delivers CHIRP traditional sonar alongside Ultra High-Definition ClearVü and SideVü scanning sonars, painting a vivid picture of the underwater world. Imagine spotting crisp fish arches with pinpoint separation, revealing bait schools, wrecks, and drop-offs in stunning detail—whether they're directly beneath your boat or lurking off to the sides.

Why This Transducer Bundle Stands Out for Anglers

The GT36-TM transom-mount transducer brings unmatched versatility to your Garmin fishfinder or chartplotter. Its advanced scanning tech captures crystal-clear images up to 400 feet for ClearVü and 500 feet for SideVü, operating across optimized CHIRP frequencies like 445 kHz, 800 kHz, and 1,000 kHz. Narrow beamwidths—such as 0.52° x 52°, 0.64° x 35°, and 1.1° x 52°—ensure exceptional target resolution, helping you distinguish between individual fish and structure even in murky water.

Paired with the GT15M-IH in-hull transducer, this bundle provides reliable mid-band CHIRP traditional sonar for consistent bottom tracking and depth readings, even at high speeds during trolling or running offshore. Both units are tailored for fiberglass hulls, with the GT15M-IH handling deadrises from 0° to 25°. The included Y-cable makes dual-transducer integration seamless, so you get the best of both worlds without compromising performance.

Key Performance Specs at a Glance

• Power Output: 500 watts for strong signal penetration
• Cable Length: 25 feet on GT36-TM for flexible routing
• Transom Compatibility: Works on angles from 0° to 70°
• Depth and Temperature Sensing: Accurate readings for navigation and fishing
• Connectors: 12-pin for GT36-TM, 8-pin for GT15M-IH, plus Y-cable adapter

Real-World Benefits for Your Fishing Adventures

Picture this: You're drifting over a reef, and SideVü sonar lights up schools hugging the structure 100 feet to starboard—targets you'd miss with standard sonar. ClearVü's photo-like views slice through the water column, showing baitfish suspending mid-water and predators ambushing from below. Anglers report fewer false readings and more hookups because superior target separation means confident decisions on lure placement or bait drops.

This bundle shines in varied conditions, maintaining lock on the bottom at speeds over 20 knots. For inshore jigging or deep-water bottom bouncing, the mid-band CHIRP from GT15M-IH delivers sharp arches and thermocline details. It's not just about seeing more; it's about fishing smarter, saving time scouting spots, and focusing on what matters—landing trophy fish.

Seamless Integration and Hull Fit

Ideal for center-console boats, walkarounds, or sportfishers with fiberglass hulls. Mount the GT36-TM securely on the transom for scanning sonar prowess, while the GT15M-IH tucks inside the hull for clean aesthetics and protection from trailering dings. Pro tip: Position the in-hull unit in a flat spot amidships for optimal performance, avoiding aerated water near the keel. The bundle's Y-cable simplifies wiring to your Garmin display, powering both transducers through a single port.

What's Included in the Bundle

• GT36-TM transducer (12-pin connector)
• GT15M-IH in-hull transducer (8-pin connector)
• Y-cable (adapts 12-pin and 8-pin to single 12-pin sounder connection)
