It offers reliable performance and durability, making it a versatile choice for various marine environments. Its lower power rating compared to the 2 kW models makes it more energy-efficient while still providing high-quality readings. This transducer is ideal for users who need a balance between performance and energy consumption.

TMM-40-50/200X-T 1 kW Dual Frequency Transducer with Temperature Sensor

This model combines dual frequency capabilities with a temperature sensor, offering versatile performance for both shallow and deep waters. Its 1 kW power rating ensures efficient operation, while the temperature sensor adds another layer of data for comprehensive marine analysis. The TMM-40-50/200X-T is perfect for users needing a comprehensive transducer that delivers accurate temperature and depth readings.

KTD-520-TM Transom Mount Transducer

Adding to ONWA’s robust lineup is the KTD-520-TM transducer. This model is a transom-mounted transducer, which means it is designed to be mounted on the boat’s transom (the flat surface at the back of the hull). It offers a blend of versatility and performance, suitable for a variety of marine environments.

Features of the KTD-520-TM:

Mounting Style: As a transom-mounted transducer, it is easy to install and ideal for smaller to medium-sized vessels.
Frequency: It operates at dual frequencies, typically 50 kHz and 200 kHz, providing versatility for different fishing conditions.
Temperature Sensor: The built-in temperature sensor offers additional data for more informed decision-making.
Durability: Designed to withstand the rigors of marine environments, it offers a reliable option for recreational boaters.

Applications and Benefits: The KTD-520-TM transducer is perfect for anglers who require a transducer that can handle diverse conditions. Its dual frequency capability allows it to be effective in both shallow and deep waters, making it a versatile addition to any fishing setup. The temperature sensor enhances its utility, providing essential data that can improve fishing success rates.

Key Features and Specifications

Frequency Range and Applications

Dual frequency transducers, like the NBM-40-50/200T and NMM-40-50/200T, operate at 50 kHz and 200 kHz, making them suitable for both shallow and deep-water fishing. The lower frequency (50 kHz) penetrates deeper waters, while the higher frequency (200 kHz) provides detailed images in shallow waters.

Material and Durability

Transducers come in various materials, with plastic and bronze being common options. Plastic transducers are lightweight and cost-effective, ideal for smaller vessels. Bronze transducers, however, are more durable and suitable for larger craft, vessels under survey, or harsher marine environments.

Power Rating

Power ratings, measured in kilowatts (kW), determine a transducer’s ability to transmit and receive signals. Higher power ratings, like 2 kW in the TGM-50-200A, provide better performance in deep waters. Lower power ratings, such as 1 kW in the TGM-50/200B-12L, are more energy-efficient and still offer reliable performance.

Temperature Sensing

Built-in temperature sensors, available in models like the NBM-40-50/200T and TMM-40-50/200X-T, provide additional data useful for fishing and environmental monitoring. Accurate temperature readings can help identify ideal fishing spots and monitor water conditions.

Choosing the Right ONWA Transducer

Identify Your Needs

First, consider the primary purpose of your transducer. Are you focused on shallow or deep-water fishing? Do you need additional features like temperature sensing? Understanding your specific needs will help narrow down the options.

Evaluate the Environment

The material and durability of the transducer are crucial factors. If you operate in harsh marine environments, a bronze transducer like the NMM-40-50/200T will offer better longevity. For calmer waters, a plastic transducer will generally be sufficient.

Consider Power Requirements

Higher power transducers provide better performance in deep waters but consume more energy. If you primarily fish in deep waters, opt for a higher power rating like the 2 kW TGM-50-200A. For more energy-efficient operation, a 1 kW transducer will suffice.

Budget and Compatibility

Determine your budget and ensure the transducer is compatible with your existing marine electronics. ONWA transducers are designed to integrate seamlessly with ONWA chartplotters and fishfinders. Heavy-duty transducers pair with the KFish-12, while others are compatible with the KP and KM series chartplotters and KFish-7.

FAQs

What is the difference between plastic and bronze transducers? Plastic transducers are lightweight and cost-effective, suitable for smaller vessels and calmer waters. Bronze transducers are more durable, ideal for larger boats and harsh marine environments.

How do dual frequency transducers work? Dual frequency transducers operate at two different frequencies, typically 50 kHz for deep waters and 200 kHz for shallow waters, providing versatility for various fishing conditions.

Why are temperature sensors important in transducers? Temperature sensors provide additional data on water conditions, helping identify ideal fishing spots and monitor environmental changes, enhancing overall fishing success.

What power rating should I choose for my transducer? Choose a power rating based on your fishing environment. Higher power ratings like 2 kW are suitable for deep waters, while 1 kW transducers offer energy-efficient performance for shallower waters.

Are ONWA transducers compatible with other brands of marine electronics? No, ONWA transducers are specifically designed to pair with ONWA electronic devices and are not compatible with other brands.

How often should I replace my transducer? Transducers are durable and can last many years with proper care. However, if you notice a decline in performance or physical damage, it may be time to replace your transducer.
