Furuno TM185HW High Wide CHIRP Transducer w/Temp Transom Mount
Furuno TM185HW High Wide CHIRP Transducer w/Temp Transom Mount — Product description
Discover the power of advanced sonar imaging on your boat with the Furuno TM185HW, a high-frequency wide-beam CHIRP transducer designed for anglers who demand crystal-clear underwater views. Mounted easily on your transom, this urethane-housed unit with a stainless steel bracket delivers exceptional performance in shallow to mid-depth waters, making it a favorite for inshore fishing enthusiasts chasing bass, redfish, or walleye.
Unlike traditional fixed-frequency transducers that can miss subtle details, the TM185HW's CHIRP technology sweeps across 150-250 kHz, painting a vivid picture of fish arches, structure, and bottom composition. Paired with its integrated temperature sensor, you'll gain valuable insights into water conditions that influence fish behavior, helping you make smarter decisions on the water.
Key Performance Highlights
- Superior Target Separation: The wide beam angle provides broader coverage, spotting schools of baitfish and game fish faster without sacrificing resolution.
- Robust Build for Harsh Conditions: Urethane housing resists impact and corrosion, while the stainless bracket ensures a secure transom fit on fiberglass or aluminum hulls.
- High-Power Output: Rated at 1kW, it punches through thermoclines and delivers reliable depth readings up to several hundred feet, ideal for coastal bays and lakes.
- Temp Monitoring: Built-in sensor tracks surface water temps accurately, helping you locate thermal edges where predators lurk.
- Versatile CHIRP Span: Adjustable frequency range lets you tune for specific scenarios—narrower for deeper precision or wider for maximum coverage.
Boat owners rave about how this transducer transforms their fish finder displays, turning fuzzy images into sharp, actionable intel that hooks more fish.
How CHIRP Wide-Beam Technology Elevates Your Fishing Game
CHIRP isn't just buzzword—it's a game-changer. Instead of a single pulse, it emits a continuous range of frequencies, compressing more data into every ping. The result? Fish show as distinct arches rather than blobs, and bottom hardness varies in shades of gray for easier structure identification.
With the TM185HW's wide beam, you cover more water per pass—perfect for trolling or drifting over flats. In real-world use, anglers report seeing bait balls at 100 feet that single-frequency units overlook, plus clearer separation between closely packed fish.
Ideal Applications
- Inshore and nearshore fishing from bass boats, center consoles, or pontoons.
- Tracking wrecks, reefs, and drop-offs in 50-300 feet.
- Everyday use with Furuno multifunction displays for seamless integration.
Effortless Transom Installation
Setting up the TM185HW is straightforward for DIYers. Position the bracket 1/3 from the transom's edge, drill pilot holes, and secure with included hardware. Run the cable through a hull gland to keep things tidy and watertight.
Pro Tips:
- Angle the transducer parallel to the waterline at speed for accurate tracking.
- Avoid air pockets by keeping the face clean and free of marine growth.
- Test in a tank or on a hose before launch to verify operation.
Most installs take under an hour, and the stainless bracket holds firm against vibration and waves.
Why TM185HW Stands Out from Narrower Models
Compared to medium or low-frequency options, the high-wide design excels where speed and coverage matter most. It's like upgrading from a flashlight to a spotlight—same power, but illuminating a wider path. Fish that hug the bottom or school horizontally pop on screen, giving you the edge in competitive tournaments or family outings.
Frequently Asked Questions
What makes the TM185HW's CHIRP different from standard sonar?
CHIRP sweeps a range of frequencies (150-250 kHz), delivering better fish separation, bottom detail, and noise rejection than fixed-frequency sonar.
What's the beam angle on the Furuno TM185HW?
It features a wide 25-degree beam at 200 kHz, providing excellent coverage for shallow-water fishing without losing too much focus.
Can I use this transducer in saltwater environments?
Yes, the urethane housing and stainless bracket are built tough for saltwater exposure, resisting corrosion and handling rough conditions.
How deep can the TM185HW detect fish?
It reliably images up to several hundred feet, optimized for inshore depths where high-frequency performance shines brightest.
Does the temperature sensor provide accurate readings?
Absolutely—the fast-response sensor delivers precise surface water temps, crucial for finding baitfish concentrations and predator zones.
Is installation DIY-friendly for beginners?
Yes, with the transom bracket and clear positioning guidelines, most boat owners complete it without professional help.
What boats work best with the TM185HW?
It's perfect for bass boats, bay vessels, and smaller offshore rigs needing wide coverage in mid-shallow waters.
