Furuno TM275LHW Chirp Plastic TM Temp Xdcr
Furuno TM275LHW Chirp Plastic TM Temp Xdcr — Product description
Imagine gliding across the water at dawn, your sonar screen lighting up with crystal-clear images of fish schools darting just beyond the drop-off. That's the edge this transom-mount transducer delivers to serious anglers chasing everything from deep-water grouper to shallow-water snapper. Engineered for boats with hull deadrises up to 28 degrees, it combines low and high CHIRP frequencies in a rugged plastic housing with a urethane acoustic window, ensuring reliable performance even in choppy conditions.
Why Wide-Beam CHIRP Changes Your Fishing Game
Traditional transducers often leave gaps in coverage, missing fish off to the sides. This model's wide-beam design doubles the search area under your vessel compared to standard high-frequency options. The high band maintains a consistent 25-degree beamwidth across 150-250 kHz, painting a broader picture of the water column. Paired with the low band's sweeping 42-65 kHz (beamwidth from 25 to 16 degrees), you get unmatched versatility—spotting bait balls near the surface or structure hugging the bottom with pinpoint accuracy.
Anglers report seeing larger, sharper returns on their displays, making it easier to distinguish individual fish from baitfish or debris. Whether you're trolling for pelagics or bottom bouncing, the 123 kHz total bandwidth covers the sweet spots around 50 kHz and 200 kHz while unlocking frequencies for specialized targeting.
Built for Real-World Demands
- Depth Precision and Temp Tracking: Integrated sensor delivers accurate depth readings and quick-response water temperature data, vital for locating thermoclines where big game hides.
- Broadband Power: Sweeps across massive frequency ranges for superior target separation and reduced clutter, even at boat speeds over 30 knots.
- Durable Construction: Urethane lens resists wear from constant water exposure, while the transom mount handles vibrations from outboards or stern drives.
- Enhanced Imagery: Constant wide beam on high frequencies creates vivid echoes, helping you zero in on hooks faster during prime bite windows.
Effortless Setup for Weekend Warriors and Pros
Installing on trailers, center consoles, or offshore rigs is straightforward. The included transom bracket and three 3-degree shims let you dial in the perfect deadrise angle for dead-on readings—no cavitation or air bubbles to muddy your screen. Position it slightly off-center from the keel for optimal water flow, and you'll be scanning in minutes. Pro tip: Clean the mounting surface thoroughly and use marine-grade sealant around the bracket for a watertight seal that lasts seasons.
Its no-connector design gives flexibility to match your existing sonar setup, keeping wiring clean and future-proof.

Frequently Asked Questions
What makes the wide beam on this CHIRP transducer special?
The high-frequency band delivers a constant 25-degree beamwidth across 150-250 kHz, providing twice the coverage under your boat compared to narrower beams, with sharper images of fish and structure.
Can it handle boats with significant hull deadrise?
Yes, it's designed for hull deadrises up to 28 degrees, with included shims for precise alignment to eliminate bubbles and ensure clear sonar returns.
Does it measure water temperature?
Absolutely, it features a fast-response temperature sensor alongside depth capabilities, helping you track thermoclines and prime fishing zones.
What frequency coverage does it offer for common fishing scenarios?
Low CHIRP from 42-65 kHz for deep water and bottom structure, high CHIRP from 150-250 kHz for shallow precision—covering 50 kHz and 200 kHz staples plus much more across 123 kHz bandwidth.
Is installation complicated for a DIY boater?
Not at all. The transom bracket, hardware, and shims make it simple to mount. Just ensure a clean surface and proper angle for optimal performance at speed.
How does CHIRP technology improve over single-frequency sonar?
CHIRP sweeps multiple frequencies simultaneously for better resolution, target ID, and less noise, revealing fish details that single frequencies often blur.
Will it work at high boat speeds?
Yes, the streamlined design minimizes cavitation, maintaining solid performance well beyond 30 knots for trolling or searching vast areas.
Airmar TM275-LHW Transom Mount Low/High Wide CHIRP Transducer with No Connector
Model: TM275LHW- Depth & fast-response water-temperature sensor
- Low - CHIRPS from 42 kHz to 65 kHz - 25° to 16° beamwidth
- High - CHIRPS from 150 kHz to 250 kHz - 25° constant beamwidth
- 123 kHz of total bandwidth from one transducer
- Covers popular fishing frequencies of 50 and 200 kHz plus everything else in the bandwidth
Get more coverage under the boat with Airmar's new wide beam Chirp product line. Offering a high frequency range of 150-250 kHz and a constant 25° Beamwidth, these transducers are truly broadband at its best. In addition to improving the performance of Chirp-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency Chirp transducers.
A unique property of the new high frequency transducers is that the Beamwidth is a constant 25° angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with our narrow beam transducers, Airmar's new wide beam format also creates crisper and larger return images on the display. We've got you covered.
