Why Do You Need a Fish Finder?

Have you ever gone fishing?  In your whole life, have you ever took a fishing rod and some type of bait and tried to lure a fish into biting?  It sounds simple enough, right?  After all, our ancestors did it.  In fact, some of the earliest pictographs depicts people fishing in the Nile.  Even today, tribes in the Amazon uses fishing as a means to feed themselves, so really how difficult can it be?

One has to take into account that there is an element of luck in fishing.  Both the fish and the angler has to be in the same vicinity at the same time.  Then there is also the fact that you have to have the right bait to lure the fish into taking the hook.  So, in the modern world at least, people who love to fish are always looking for ways to push luck over to their side.  One way they do this is by using a fish finder. You can find best portable fish finder here.

So, what is a fish finder?  To explain exactly what this is, it is a modern piece of equipment, based on technology which was originally designed for military use.  Sonar and radar was developed by countries which used it to spot enemy planes and submarines. It gave the user the advantage of locating incoming crafts, either in the water or in the sky.

This is the basic principles of a fish finder.  Mounted on a boat, the fish finder emits a sonar wave, which radiates outward.  When the sound waves hits an underwater object, such as fish or the bank of the pond, it slows down and is reflected back to the device, where it is picked up by the receiver. 

The computer embedded in the device then translates the sound waves into a type of picture which can be displayed on the screen.  Not only does it display information regarding the location of the fish; but, it also tells the operator the depth of the water and any other obstacles, such as fallen logs and other debris, which maybe a danger to the boat.

Some of the most modern fish finders also have a GPS application which can track, down to meters, where the boat has been on the water.  This can come in handy if a person needs to remember the exact spot he or she caught ‘the big one’, where there were no fish at all; or, in the worst case scenario, help a lost motor boat operator find his or her way back to dock.

In reality, there are many uses for a fish finder, and not all of them have to do with finding fish.  Today, there is some debate if the use of these machines is ethical sense it does seem to give an unfair advantage to the fisherman.  Some animal rights activists are protesting their use since the only defense fish have is the ability to hide and a fish finder can take it away.
