Unlock Crystal-Clear Views Beneath and Beside Your Boat

Imagine gliding across freshwater lakes at speed, yet still pinpointing schools of walleye hiding in submerged timber or bass cruising along drop-offs. This Garmin transducer bundle combines the best of traditional CHIRP sonar with advanced scanning capabilities, delivering fish arches that pop and structure images so detailed, you'll feel like you're diving with your catch. Tailored for serious freshwater anglers on fiberglass hulls, it eliminates guesswork and amps up your success rate on every outing.

The secret lies in its dual-transducer setup: one mounted inside the hull for unwavering performance at high speeds, the other on the transom for ultra-detailed side and down scans. No more blurry returns or lost signals— just reliable, high-definition intel that keeps you ahead of the fish.

GT30-TM Transom Mount: Your Window to SideVü and ClearVü Scanning

The GT30-TM shines when you need to scout wide areas without disturbing the water. Its CHIRP ClearVü sweeps straight down with photo-like clarity, revealing bottom composition, weed edges, and suspended baitfish. Switch to SideVü, and it paints a panoramic view up to hundreds of feet port and starboard—perfect for locating humps, points, or schools before they vanish.

With dual frequencies at 455 kHz and 800 kHz, it balances coverage and resolution. Anglers love how it cuts through thermoclines and cluttered bottoms, making it a game-changer for tournament pros targeting structure-oriented species like crappie or pike.

• Exceptional target separation for distinguishing individual fish in tight pods.
• Handles transom angles up to 70 degrees, fitting most modern bass boats.
• Tracks temperature swings to dial in lure choices on changing days.

GT8HW-IH In-Hull Mount: High-Speed Traditional Sonar That Delivers

For those pushing 40+ mph, the GT8HW-IH in-hull design keeps readings steady without drag or cavitation issues. Its high-wide CHIRP beam (145-230 kHz) covers massive swaths underwater, locking onto bottom contours and fish even in rough chop.

Installed seamlessly through a hull fitting on shallow deadrises (0-6 degrees), it thrives on planing hulls where external mounts falter. Expect consistent depth locks to 800 feet in freshwater, helping you navigate deep reservoirs or Great Lakes tribs with confidence.

• Wider beamwidth for broader searches during trolling or drifting.
• Minimal signal loss through fiberglass—proven on thousands of setups.
• Complements scanning sonar by filling in traditional 2D views for precise jigging depths.

The Ultimate Pairing for Speed and Detail

Together, these transducers create a complete sonar suite via the included Y-cable adapter. Run high-wide traditional from the in-hull for navigation and bottom tracking at full throttle, then flip to transom-mounted scanning for dialed-in presentations. This bundle excels on walleye runs, bass tournaments, or musky hunts where every detail counts.

Freshwater-focused frequencies ignore saltwater clutter, while 500W power punches through mud lines and heavy cover. Real anglers report doubling hookups by spotting fish others miss, turning average days into limits.

Seamless Setup on Fiberglass Hulls

Designed for deadrises from flat to slight V (0-6 degrees), installation preserves hull integrity and performance. The in-hull model uses a simple thru-hull fitting with sealant, while transom mount hardware secures firmly against vibration. Both 20-foot cables reach modern consoles easily.

Pro tip: Pair with Garmin's Quickdraw Contours to build custom maps on the fly, storing hotspots for future trips. It's all about low-maintenance reliability that lets you focus on fishing.
