When it comes to transducers on fishing electronics, there are single frequency transducers and dual frequency transducers. Single frequency transducers are used for lakes, while dual frequency is used when you are fishing in deep water. In deep water, the higher frequency transducer on a dual transducer fish finder is the one that shows all the fish.
You can also get display screens on marine electronics with many different resolutions. Of course, the higher the resolution, the better the image. Color screens are better viewed in direct sunlight. The overall size of the monitor may be anywhere from four to seven inches, measured on the diagonal. Generally, the more power your fishing electronics come with, the better are the results, even in still or shallow water. Depth penetration is related to the quality and the power of the transducer. Better transducers penetrate the water best. Saltwater and muddy water will … Read the rest
