Garmin GT41-THP THRU-HULL Pair Downvu/Sidevu 12-Pin
Garmin GT41-THP THRU-HULL Pair Downvu/Sidevu 12-Pin — Product description
Unlock Superior Fishfinding with Garmin GT41-THP Thru-Hull Transducers
Imagine gliding through choppy waters, spotting fish hiding near structure or schools darting off to the sides— all with razor-sharp clarity. The Garmin GT41-THP thru-hull transducer pair delivers that edge for serious anglers and boaters. Mounted directly through your hull, these stainless steel units cut through rough conditions to provide DownVü and SideVü scanning sonar alongside powerful traditional sonar. Optimized for boats with hull deadrises up to 25 degrees, they excel in delivering reliable performance whether you're trolling offshore or navigating inland waters.
What sets this pair apart? Dual transducers—one for port, one for starboard—ensure balanced coverage without compromising signal strength. The built-in temperature sensor keeps you informed on water conditions that influence fish behavior, helping you adapt your strategy on the fly.
Key Features and Performance Highlights
- DownVü/SideVü Scanning Sonar: CHIRP technology at 260/455 kHz paints detailed, photo-like images of the bottom, wrecks, and fish directly below and up to 750 feet to each side. Perfect for structure fishing in lakes or bays.
- Traditional CHIRP Sonar: 50/200 kHz frequencies punch through to 1,500 feet in saltwater, ideal for deep-water pursuits where every detail matters.
- Robust Power Output: 500W per DownVü/SideVü element (1,500W total) and 600W traditional—handles turbulent wakes and heavy seas without losing resolution.
- Stainless Steel Construction: Corrosion-resistant stems withstand harsh marine environments, ensuring longevity even in saltwater exposure.
- Fast-Response Temp Sensor: Tracks subtle water temperature shifts to pinpoint thermoclines where baitfish congregate.
Boaters report transforming their setups with this pair, turning vague sonar returns into actionable intel. In real-world use, it shines during low-light conditions or murky waters, revealing bait balls and predators that traditional sonar might miss.

Easy Installation for Lasting Results
Installing the GT41-THP pair is straightforward for DIY-savvy boat owners. Drill through the hull (following safety guidelines), secure with the included stainless steel stems, fairing blocks, and isolation hardware to minimize turbulence. The Y-cable simplifies wiring to your 12-pin Garmin display. Pro tip: Align transducers parallel to the waterline for optimal beam spread, and bed them in marine sealant for a watertight fit. Fairings reduce drag, maintaining hull speed while enhancing sonar accuracy in high-speed scenarios.
Users with fiberglass or wood hulls appreciate the vibration-dampening bushings, which keep readings steady even at planing speeds.

Frequently Asked Questions
What boats is the Garmin GT41-THP best suited for?
It's designed for vessels with hull deadrises of 25 degrees or less, such as many fiberglass planing hulls common in fishing boats and cruisers. Check your hull angle for a perfect match.
How does DownVü/SideVü differ from traditional sonar?
DownVü gives downward-facing, photo-like images for bottom detail, while SideVü scans horizontally up to 750 feet per side—great for spotting fish off the beam that cone-shaped traditional sonar might overlook.
What's the maximum depth for this transducer pair?
DownVü reaches 1,000 feet straight down, SideVü up to 750 feet left/right, and traditional sonar to 1,500 feet in saltwater—ample for offshore adventures.
Does it work in rough water conditions?
Yes, the high power ratings and thru-hull design maintain clear images through wakes, waves, and boat traffic, outperforming transom-mount options in turbulent seas.
Why choose a transducer pair over a single unit?
The port/starboard pair provides symmetrical coverage, eliminating blind spots and improving side-scan resolution across your full beam width.
Is professional installation required?
Many install it themselves using the detailed instructions and hardware provided, but consult a marine technician if you're unsure about hull drilling or wiring.
Garmin GT41-THP Stainless Steel Thru-Hull Pair
