Technology has made fishing a great deal easier. Just consider how difficult it must have been in the past when they had to use the trial and error method to locate fish and determine depth.
Fish finders are useful devices that use sonar to locate the fish under the water and therefore increase the fisherman’s chances of catching fish. There are several different types of fish finders on the market today, so regardless of what type of fish you are hoping to catch, a fish finder can be a great help.
There are two basic types of screens used with fish finders. The first type of screen is known as the Cathode Ray Tube (CRT) and the second is called a Liquid Crystal Display (LCD). CRTs are not as popular since the invention of the LCD screens. This is because LCD screens are able to display high resolutions. If you find a screen labeled as a TFT screen, it is just another version of the LCD screens.
For the average fisherman the CRT screen is the most sensible choice. It costs less than an LCD unit, provides very good clarity and is easy to read in direct sunlight.
Another thing you need to think about when searching for a fish finder is your budget; you do not want to get your heart set on an item that is out of your price range. The best way to avoid this issue is to search for those finders that are within your allowable price range and forget about the rest.
Keep in mind when deciding on a budget that a colored screen will be more expensive than a non-colored screen. It is usually the case that a more regular fisherman will spend more on a fish finder than the occasional fisherman.
Another technical aspect of the fish finder is the frequency it employs. Frequency is measured in kilohertz (kHz) and is used in the water to find where the fish are and where the best place to cast a line will be.
The screen on the finder is unable to tell you precisely the type of fish available, just where groups of fish can be found, so it is important to know the depth. The best kHz is between 80 and 125 kHz, because the higher the frequency, the narrower is the signal range cone and the greater the detail available to you.

Whether you choose a regular fish finder or one with GPS, it will prove to be a fantastic addition to your other fishing equipment. Allow yourself to dream about how many more fish you will be able to catch with a great fish finder and how easily you can get back to that fantastic place if you have to leave for any reason.
