Professional Fish Finder is made by OVA adopting high precision digital signal processing technology(DSP).

 

6" TFT LED-backlit LCD professinal display provides superior viewing even in direct sunlight and night.You can see every fish in many different ways,Let you enjoy the happiness of fishing.We have been working on echo sounder and fish finder for many years.

 

 

1. Advanced Traditional Sonar Technology
The Professional Fish Finder leverages proven sonar principles to provide reliable, real-time data. Its 600W transducer emits sound waves that bounce off underwater objects, translating reflections into detailed images on your display. Unlike lower-powered models, this system ensures minimal signal loss even in challenging environments, such as deep waters or areas with heavy vegetation.

 

2. Dual-Frequency Flexibility (50 kHz & 200 kHz)
Switch seamlessly between 50 kHz and 200 kHz frequencies to adapt to any fishing scenario:
50 kHz: Ideal for deep-water scanning (up to 3,000 feet), this low-frequency mode offers wide coverage (up to 120° beam angle), making it perfect for locating schools of fish or large structures in open seas.
200 kHz: Optimized for shallow waters (up to 1,000 feet), this high-frequency mode delivers razor-sharp resolution with a narrow beam (up to 45°). Use it to identify individual fish, underwater contours, and small structures like rocks or wrecks.

 

3. High-Resolution Display & Intuitive Interface
The device features a vibrant, sunlight-readable screen that renders sonar returns in crisp detail. Customizable color palettes and adjustable sensitivity settings let you distinguish between fish, vegetation, and the seabed effortlessly. User-friendly menus and one-touch frequency switching ensure even beginners can operate it with confidence.

 

4. Durable, All-Weather Design
Engineered for harsh marine environments, the Professional Fish Finder boasts a waterproof, corrosion-resistant housing. Its transducer is built to withstand impacts, UV exposure, and saltwater, guaranteeing longevity whether you're fishing in tropical seas or icy lakes.

 

5. Enhanced Target Identification
Advanced noise-filtering algorithms eliminate interference from waves, thermoclines, or boat movement. Fish arches, depth markers, and size indicators appear clearly, allowing you to differentiate between species and avoid non-target catches.
