With the advantages of technology, fishing has become a great deal easier. Just think about how difficult it must have been in the past when all that was available was the trial and error method to locate fish and determine depth.
Fish finders are handy devices that utilize sonar to locate the fish under the water and therefore enhance 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 looking 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 have lost popularity since the invention of the LCD screens. This is because LCD screens have the ability to display high resolutions. If you find a screen that has been labeled as a TFT screen, it is just another version of the LCD screens.
For the recreational fisherman the CRT screen is the wisest choice. It’s less expensive than an LCD unit, provides very good clarity and is easy to read in direct sunlight.
Another point you need to consider when on the lookout 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 approach this is to search for those finders that are within your possible 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 casesituation that a more regular fisherman is more likely to spend more on a fish finder than the occasional fisherman.
Another technical aspect of the fish finder is the frequency it uses. The measurement used to determine frequency is kilohertz (kHz) and is used in the water to locate where the fish are and where the best place to cast a line will be.
The screen on the finder is not able to identify the type of fish available, just where groups of fish are located, 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.
One other important factor to consider is the inclusion of a global positioning system. GPS fish finders are an excellent tool to use when you are going for a weekend trip and you don’t know the area very well. They allow you to record any position in the system, which means you can locate it again any time you want, without any problems.
Whether you decide to purchase a regular fish finder or one with GPS, it will prove to be a fantastic addition to your other fishing equipment. Just imagine 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.
