Commercial Fish Finders
Commercial fish finders can be used for a variety of applications. Most models use an underwater transducer to transmit an electrical impulse. This pulse reflects off the bottom of the water and is reflected back to the finder. The power of the pulse and frequency of the signal can affect how far the fish can be located. The sound wave travels at a speed of approximately 1500 m/s in seawater and about 4800 ft/s in freshwater. By knowing how long the wave takes to travel in seawater and freshwater, a commercial fish finder can estimate how much time it will take before it encounters the fish. best kayak fish finders
A high-quality commercial fish finder will provide more details on the display than a low-frequency fish finder. Low-frequency fish finders are used for commercial fishermen and deep-sea trawlers. Modern fish finders feature multiple frequencies and split-screen displays. If you are fishing in colder waters, you may want to invest in a fish finder with buttons instead of touchscreen controls.
Commercial fish finders may also use sonar-like technology, which involves sending acoustic pulses into the water and detecting the echoes of the pulses off objects submerged in the water. Commercial fish finders with this technology can also provide details about the location and approximate size of shoals. However, assessing the actual number of fish is more challenging because animals on top and underneath the shoal tend to shield the acoustic pulses.
A commercial fish finder can be difficult to use if you don’t know how to use it. A good commercial fish finder will be easy to use and have several features that can make your fishing trip a success. Its screen and interface are easy to use and the unit is easy to install. Among the features of a commercial fish finder include CHIRP imaging, structureScan, and multiple display options. A fish finder with these features can be very expensive, but it’s well worth the price.
The Lowrance Corporation has a massive presence in the recreational fish finder market. Without exclusivity, Computrol will have difficulty entering the Lowrance market. Lowrance has an extensive product line and relationships with major national retail chains. Its product line, Fishin’ Buddy, is now sold at numerous national retail outlets.
The patent ‘912 Patent covers a new method for analyzing side-looking sonar data. Previous methods used to detect fish relied on two closely spaced echoes. This method, however, is not obvious. The Latham patent reflects an important change in fish detection. Prior to Latham, fish finders were intended to identify as many fish as possible.
While a side-looking fish finder has a side-scanning or down-looking mode, it still has many benefits. It can provide information on fish that are closer to the boat. Many Lowrance products have an Eagle ScanPac feature, which allows the user to find fish to the side of the boat. Among these products are the Magna II portable, Ultra II+ and UntraNav II GPS. X-55 is another model that uses the side-scanning technique.
