Fish Finders From Radio World

While most anglers can afford to purchase a side image sonar fish finder or a down image sonar, more advanced fishermen may want to consider a combination chart plotter and sonar unit. A fish finder will help you find and note schools of fish, as well as their depths. Avoid schools of fish that seem to be huddled together, as they are usually inactive and on the bottom. humminbird fish finders for sale

These fish finders feature dual transducers that can operate simultaneously or independently. This feature is especially useful if you want to fish from a canoe or kayak, but you can also get a model that will work in ice waters. Dual transducers also offer flexibility, with some models being able to transmit on high and low frequencies. Higher frequencies offer greater depth penetration, but require less power and produce less noise. Lower frequencies, on the other hand, provide fine detail in shallow to mid-water depths.

High-frequency sonars work best at depths between 100 and 200 feet, and are effective at detecting submerged objects, such as fish and other organisms. However, higher frequencies lose their effectiveness when reading depths greater than 200 feet. However, learning to read high-frequency sonar images is very intuitive and you’ll soon be catching more fish than you ever thought possible. And if you’re playing the game on a PC, you can also turn off the autosave feature, so that you don’t have to save any progress unless you’re ready for it.

CHIRP (Chiral Infrared): This kind of transducer transmits a wide-band frequency modulated signal from 40 to 75 kHz. This signal is long enough to distinguish individual fish. This CHIRP sonar can separate individual fish and group them easily. In addition to this, it also offers high-resolution imaging and can help you identify the smallest of details, including tiniest fish.

JRC: A company that makes marine electronics for merchant vessels, Japan Radio Company has been in business since 1915. They created a radio transmitter for ship-to-shore communications in 1932 and began using microwave communication technology in the 1940s. The company has made some excellent fishfinders and their radar development is used in ships all over the world. The three basic models of JRC fishfinders are excellent examples of modern marine electronics.
