Detailed description

The Airmar CM599LH is a CHIRP cavity transducer designed for depth detection and temperature measurement, offering extended coverage across two distinct frequency bands: low frequency (LF) and high frequency (HF). This CHIRP technology delivers increased resolution and detail, up to 5 to 10 times greater than traditional transducers.

Low Frequency (LF) Band: 28-60 kHz

The low-frequency section of the CM599LH operates within the 28 to 60 kHz range. It features a nominal power of 3 kW (at 1 % duty cycle) and a continuous wave (CW) power of 40 W for CM599 and R599 models, in seawater at 20 °C. Its active surface area is 229.9 cm² (35.63 in²) with an epoxy radiating surface. The -3 dB beam widths are 11°/23° at 28 kHz, 7°/13° at 45 kHz, and 5°/9° at 60 kHz. The C44-type cable has a length of 15 m.

High Frequency (HF) Band: 130-210 kHz

The high-frequency section covers the 130 to 210 kHz range, with a nominal power of 1 kW (at 1 % duty cycle). The active surface area of this element is 33 cm² (5.1 in²) with a urethane radiating surface. The -3 dB beam widths are 8° at 130 kHz, 8° at 150 kHz, and 6° at 210 kHz. The CM599LH transducer integrates a fast-response temperature sensor. The assembly is connected via a 15 m Airmar C44-02 cable.

Design and Applications

Designed for cavity installation, this transducer is specifically suited for fiberglass hulls. It is particularly effective for recreational and commercial fishing, both inshore and offshore, and enables detailed seabed mapping, including deep canyons and seamounts. The CM599LH transducer is a tool for underwater structure exploration and target identification with improved clarity.

Expert opinion

« Technical analysis: Airmar CM599LH CHIRP dual-band transducer »

The Airmar CM599LH is a transducer of choice for demanding fishing applications, whether recreational or commercial, particularly for deep-water targeting. Its CHIRP dual-band frequencies (28–60 kHz and 130–210 kHz) provide significant operational flexibility, allowing users to adapt their scan to marine conditions and target types. The low-frequency band is optimized for deep penetration and detection of large echoes, while the high-frequency band excels in resolving detail and separating targets near the bottom or in mid-water.

Installation of this transducer requires a recessed mount, making it specifically suited for fiberglass-hull vessels. This mounting method, though more complex than a through-hull or transom installation, minimizes hydrodynamic disturbance and maximizes acoustic performance by avoiding turbulence. Careful planning is essential, including creating a cavity in the hull, using cutting templates, and applying a 6 mm marine sealant on contact surfaces, including the transducer lip. It is imperative to check for leaks immediately after launching and not to leave the vessel unattended for more than three hours.

The nominal power of 3 kW on the low-frequency band and 1 kW on the high-frequency band, combined with CHIRP technology, gives the CM599LH remarkable sensitivity—up to 6,100 times that of a baseline B45 transducer on the low-frequency band. This capability translates to superior target detection and discrimination, even in noisy environments or at significant depths. For optimal integration, it is crucial to keep the transducer away from sources of electrical or acoustic interference (propellers, shafts, other machinery) to preserve signal quality and the effectiveness of the fishfinder’s gain settings. This model represents a significant investment for professionals and sport fishermen seeking underwater data of maximum clarity and precision.

Frequently Asked Questions

Need help? Contact us

What are the operating frequencies of the Airmar CM599LH transducer?

The Airmar CM599LH transducer operates on two CHIRP frequency ranges:

Low frequency (LF): 28 to 60 kHz
High frequency (HF): 130 to 210 kHz
These ranges enable versatile detection for different depths and target types.

What is the nominal power of the CM599LH transducer for each frequency range?

The Airmar CM599LH transducer has different nominal power ratings for its two frequency ranges:

For the low frequency range (28–60 kHz), the nominal power is 3 kW (at 1 % duty cycle).
For the high frequency range (130–210 kHz), the nominal power is 1 kW (at 1 % duty cycle).

What data does the Airmar CM599LH transducer provide?

The Airmar CM599LH transducer is equipped with built-in sensors to measure depth and water temperature. These data are essential for navigation and fishing condition analysis.

What is the advantage of the CHIRP technology used in the CM599LH transducer?

The CHIRP technology in the CM599LH transducer delivers 5 to 10 times the detail and resolution of conventional transducers. This improves target separation and enables more precise detection of fish schools and underwater structures.

What is the length of the cable supplied with the Airmar CM599LH transducer?

The Airmar CM599LH transducer is supplied with a 15 m (50 ft) cable.

What is the active area of the low-frequency element in the CM599LH transducer?

The active area of the low-frequency element (28–60 kHz) of the Airmar CM599LH transducer is 229.9 cm² (35.63 in²).

What is the active area of the high-frequency element in the CM599LH transducer?

When installing the transducer, a 3 mm (1/8") pilot hole is required. Bolt holes must have a diameter of 11 mm (7/16").

Where should I position the transducer to avoid interference?

To minimize interference, the transducer should be installed away from power sources and radiation emitters such as propellers and their shafts, other machinery, other fishfinders, and other cables. Reduced noise levels allow for higher gain settings on the echosounder.

Is it important to check for water tightness after installing the transducer?

Yes, it is imperative to immediately check for leaks when the boat is launched. It is strongly advised not to leave the boat unattended for more than three hours, as even a minor leak can lead to significant water accumulation.
