Airmar TM165HW Wide-beam Transom Mount
Maximize the coverage under your boat and see what you’ve been missing. The Airmar TM165HW is a 600W transducer that features a high-frequency range of 150 to 250 kHz and a super-wide beamwidth, averaging 30°, providing maximum coverage across the frequency band. In addition to improving the performance of Chirp-capable fishfinders, anglers using this new wide-beam transducer will achieve three times the coverage compared to standard high-frequency Chirp-ready transducers.
Wide beamwidth, together with the high-frequency range, provides vast bottom coverage and precise fish detection in the upper-water column that can sometimes go unseen with narrow-beam transducers. Airmar’s new wide-beam format also creates crisper and larger return images on the display.
Features
- Depth and fast-response water-temperature sensor
- 600 W with a maximum depth of 152 m (500’)
- High frequency: 150 to 250 kHz
- Super-wide 30° average beamwidth
- 100 kHz of total bandwidth from one transducer
- Covers popular fishing frequency of 200 kHz plus everything else in the bandwidth
- High frequency delivers superior shallow-water performance, bottom detail, and fish-target separation
- High wide beamwidth yields more coverage for detecting fish in the upper-water column
- Plastic release bracket protects sensor from frontal impact
- Chemical and impact-resistant plastic housing
- Recommended for planing hulls
- Exclusive Xducer ID® technology
The Benefits of AIRMAR’s Chirp-ready Transducers
• One broadband transducer covers up to 117 kHz of bandwidth – greater opportunities to detect fish in the water column
• Superior resolution – precise separation between baitfish and gamefish represented on the display with crisp images
• Enhanced bottom fishing – resolve targets close to the bottom or near structures/wrecks
• Amazing detail – recognize haloclines and thermoclines
• Improved signal-to-noise ratio – find fish and track bottom at high boat speeds
Benefits of Transom Mount Transducers
Transom models are best suited for small and trailered vessels where a thru-hull installation is not practical. Perfect for freshwater boat styles and centre consoles. Simple to install and ideal for small trailered vessels where a thru-hull may interfere with loading.
• Simple installation on the transom of the boat
• Great performance at boat speeds below 30 knots
• Easy maintenance and low-cost replacement
Why does Frequency Matter?
Selecting the best frequency for your specific application is very important. The good news is that once you know what frequency will work best for the type of fishing you do, there’s an AIRMAR transducer designed to maximize the performance of your sounder.
AIRMAR Chirp transducers are available in various frequency combinations:
Dual Band:
|
Single Band:
|
Low Frequency = Greater Depth (ex. 42-65 kHz)
• Sound waves will not present as clear a picture of the bottom on the display but will sound down in very deep areas where high-frequency sound waves cannot reach
• Provides greater depth range, wider beamwidth, and ultimately more coverage under the boat
• Chirp signal processing technology used with AIRMAR broadband, Chirp-ready transducers provide more detail at greater depths and are less susceptible to noise
• Great for operating at high boat speeds
High Frequency = Greater Detail (ex. 130-210 kHz)
• More sensitive to small targets and will send back detailed information which will display as crisp, high-resolution images on the echosounder screen
• Best for shallower water and is popular with anglers fishing at depths less than 1500 feet
Medium Frequency = The Best of Both Worlds (ex. 80-130 kHz)
• Provides the ability to sound deeper than the high frequency, along with better resolution than the low frequency
• Wider beam than the high frequency, achieving more coverage under the boat and greater opportunity to find fish
• Clear images at higher boat speeds
