Fish finders have become indispensable tools for anglers and fishing enthusiasts. They use sonar technology to detect and show the location of fish and other underwater structures in real-time. Many fish finders are on the market, and choosing the best one for your requirements can be challenging. The frequency of the sonar signals determines the level of detail and accuracy of the information shown on the screen.
Saltwater is more conductive than freshwater, making detecting fish and other underwater structures challenging. A fish finder specifically designed for use in saltwater is recommended for anglers fishing in that environment. This article will illustrate factors that make a fish finder ideal for detecting large fish at a depth of 13 feet. One of the most crucial factors to consider is its frequency range.
How do Sonars Work in Detecting Large fish?
There has been a long debate about how sonars actually Work as it is the most searched thing of the main working mechanism of sonars. Sonar mainly works based on great and long module CHIRP and photo-realistic imaging. The awesome combination of the sonars and the system of transducers works in a great way, which is the prime reason for having such a diverse mechanism for searching for fish underwater. Marine inclusions are regarded as one of the most confusing areas on the earth’s surface. According to that, you need a really liberal technique for catching fish in such an environment. 
The acme functionality of the sonar is nothing but the sensor technology in an entire set of different frequencies. At last, they send rays underwater, and it reflects in a traditional way. This return of the rays is the main cause of finding schools of fish. This gives more comprehensive information about the inner ambiance of the river or sea. The first step includes sending a transducer sound wave into the water and, in the response item, analyzing such waves and frequencies that denote whether it is a type of fish or The entire system is designated as a ping. The sound wave or ping is mainly an audible sound, and this tone creates a great range of vibration. Every object has a different set of specific frequencies.
Understanding the angle cone technology
The performance of the sonar is so much dependent on The size of the scannable area. This is always affected by the angle of the cone it produces. Normally a wide beam cone has the ability to scan in between 40° to 60 °. It is like a large area covered by the same type of pristine. The capability of a narrow cone insists between 10° to 20°. The system’s success depends on the fish finder’s wide or narrow cone or angle. So sure you’re aware of having the proper instinct of the circumstances of data on the screen.
The Deeper pro+ two uses a wide, medium, and narrow beam to find fish. There are different types of scanning modules, like the 7°, 47°, and 20° cones. The wide and narrow beam combination works better than the single-phase cone. Scanning between 15° and 55° is the most frequent angle used by the anglers. The Deeper medium or wide beam is ideal for catching the largest fish. Since sonar is constantly sending and receiving data, it was so much more possible to be in the condition of scanning data. Keep in mind that the left on the screen detects the older data. That’s how the sonar system finds fish.
Best fish finder options for finding large fish (below 13 feet)
A high-resolution screen will also enhance the image quality and provide better detail. A fish finder with a screen size of 5 inches or more and a resolution of 800 x 480 pixels or higher is recommended for detecting large fish at 13 feet. Transducer technology is also essential to consider when choosing a fish finder. A transducer is the component of the fish finder that sends out and receives the sonar signals. Different types of transducer technologies provide different levels of accuracy and detail.
A dual-beam transducer is better for detecting large fish at greater depths than a single-beam transducer. A fish finder with a dual-beam transducer and a frequency range of 83-200 kHz is ideal for detecting large fish at a depth of 13 feet. Another colossal factor to consider when choosing a fish finder is the type of water you will be fishing. Different types of water, such as freshwater or saltwater, can affect the accuracy and performance of the fish finder. Here are some best fish finder options for finding large fish,
Lowrance HDS-9 Live
This fish finder is a high-performance option that offers a 9-inch display with high resolution and brightness. It has a powerful 500-watt RMS transducer that provides excellent accuracy and detail. The Lowrance HDS-9 Live also has a frequency range of 83-200 kHz and is designed for use in both freshwater and saltwater environments.

This fish finder is a top-of-the-line option with a large 9-inch screen and high-resolution display. It has a powerful 500-watt RMS transducer and a frequency range of 83-200 kHz, making it ideal for detecting large fish at a depth of 13 feet. The Humminbird Helix 9 Mega SI GPS also features GPS technology, allowing you to mark your favorite fishing spots and navigate them easily.
Check the Review on AmazonA frequency range of 83-200 kHz is ideal for detecting large fish at a depth of 13 feet. Another crucial factor to consider is the power of the fish finder. The strength of a fish finder is calculated in watts, and it determines the strength of the sonar signals that are sent out and received.
Garmin Striker Plus 9sv
This fish finder is a high-performance option that offers a 9-inch display with high-resolution and high brightness. It has a powerful 500-watt RMS transducer that provides excellent accuracy and detail. The Garmin Striker Plus 9sv also has a frequency range of 77-200 kHz and is architectured for application in fresh and saltwater environments.
Check the review on AmazonThis higher-power fish finder will provide better accuracy and detail than a lower-power one. For detecting large fish at 13 feet, you need an ultimate fish finder with a massive power of 500 watts RMS. Screen size and resolution are also important factors when choosing a fish finder. The screen size will provide a more detailed and transparent image, making seeing the fish and other underwater structures easier.
Raymarine Axiom 9 RV
This fish finder is a high-performance option that offers a 9-inch display with Low high-resolution resolution. Here is a point of interest for all kinds of subjects of proper distance resolution. Individual soundwaves have several more things to do with the higher frequencies. Fish imaging has got better with the help of a larger frequency mechanism. Detailed fish finder images are only possible with a high-frequency sonar system.

A low-frequency sonar is just the opposite of high-frequency sonar manual technology. It has got several more types of advantages, especially for underwater mechanisms. The wavelength of 50 kHz is often thrown away by the transducer, and the return of the wavelength makes it more efficient for being to the latest less resistance for a greater depth. Low frequencies work more efficiently than ground conditions. The sound waves all the time penetrate deeper into the reflected arena.
The coastal regions may have the inclusion to have been in 200 kHz frequency sound waves. The screen remains blank if the frequency is transmitted into the small beam angle. The transducer has a significant impact on sound waves. The ceramic bonded transducer makes a large two sides coated, which is more conductive than the original one. The electrical materials must be within the range of a more elongated, and it has to be in a 200 kHz and 20° range. The diameter of 1 inch is mainly the right frequency for a high-quality fish finder.
Final Words
So many fish finders on the market can detect large fish at a depth of 13 feet. When choosing a fish finder, it is essential to consider factors such as frequency range, power, screen size and resolution, transducer technology, and the type of water you will be fishing. The five fish finders mentioned above are some of the best options available, each offering high-performance features and excellent accuracy and detail. Low-frequency signals (50-83 kHz) are best for detecting large fish at greater depths, while high-frequency signals (192-200 kHz) are more suitable for shallow water and smaller fish. This article discussed some useful methods of finding a large fish with conclusive techniques. We hope you got to benefit from this one.
