Higher frequencies usually work better in shallow waters, while lower frequency model provides more accurate data in deeper water. High and LowįInaly there is the difference in frequency. And we all know how much clearer image means. Besides having a bigger reach, devices with more power will provide with a clearer picture. But what is it important to have more power in your device? More power enables you to scan deeper into fresh or salt water. Smaller fishfinder may require as little as few hundred watts RMS, while larger devices need thousand watts or more to run. These displays will provide a very accurate picture of fish activity as well as structures and the bottom of the lake, pond or river that you’re fishing in.Īnother thing that you should think about when buying a fishfinder is how much power it requires. If you’re looking for a device with a decent image quality, 480 pixels screen will provide with just what you need to get a clear picture of what’s going on bellow the water surface. The number of pixels on your display determines how detailed the image on your screen will be. The next thing you should think about is the picture quality. Bear in mind that a bigger screen adds to the price of the device, which is only natural. Screen sizes can vary from as small as a 3.5-inch screen, over a 5-inch display, to a 7-inch or even larger display. Next there is the screen size and affordability. Combine those two functions onto a single screen, and you'll get all the data that you need to easily track underwater activity. It can be really handy, especially if you're using a smaller boat. The first question that you should be asking yourself is whether you want your fishfinder integrated with a GPS Chartplotter.
