Technology has made fishing much easier. Consider how in the earlier days they had to use the trial and error method to locate fish and determine depth. Fish finders are devices that use sonar to find the fish under the water to increase the fisherman's chances of catching fish. There are a ton of different fish finders on the on the market today, so no matter what type of fish you are looking to catch, a fish finder can help you.

When you are looking at several different fish finders there are two differences in screens. The first type of screen is called the Cathode Ray Tube (CRT) the other is called a Liquid Crystal Display (LCD). CRTs have become increasingly less popular since the invention of the LCD screens. This is because LCD screens are able to display high resolutions. If you see a TFT screen it is just another version of the LCD screens.

For the average fisherman the CRT screen is your best choice. It's cheaper than a CRT unit and provides very good clarity and can be read well in direct sunlight.

Another thing you need to consider when looking for a fish finder is your budget; you do not want to get your heart set on something you cannot afford. The best thing to do is search for ones that are in your possible price range and not worry about the rest. If you are looking for a colored screen you are going to end up spending more money than you would on a plain, non-colored screen. Those who fish on a regular basis are more likely to spend more on a fish finder than those who only fish on occasions.

Now lets get into the more technical information like the frequency. kHz is a representation of frequency. This is what is used in the water to locate where the fish are so you know where the best place to cast your line is. The screen will not be able to show you specific types of fish but where groups of fish are located, so depth is important. The most ideal kHz would be between 80 and 125 kHz. The higher the frequency the narrower the signal range cone and greater detail.

Another thing you need to think about is whether or not you want to have a global positioning included in your fish finder. GPS fish finders are great for going on those weekend trips or somewhere you may not know your way around very well. You can easily record any position in the system and the GPS fish finder will be able to locate it again for you without problems.

Having a regular fish finder or a gps fish finder will be a great addition to your other fishing equipment. Just think of how many more fish you will likely catch with a great fish finder and how easily you can get back to a great spot if you have to leave for any reason. Just use this article to guide you when buying the perfect fish finder for all you fishing trips.
