How do fish finder's work? You're out on your boat fishing, and you can't see any fish anywhere, but your fish finder can see every fish around your boat. How is a fish finder able to see the fish that your eyes can't?
A fish finder works using SONAR technology to locate fish in
the water below a watercraft as well as judge how deep the water
surrounding the watercraft is. SONAR stands for Sound Navigation
and Ranging.
The way a fish finder works is by first attaching a fish finder
to a watercraft, and driving that watercraft out into an area
of water. The fish finder sends out an electronic impulse out
into the water below the watercraft that is translated into a
sound wave as it hits the water below it.
When the sound wave
hits something in the water (such as a fish) it rebounds back
to the receiver part of the fish finder and a fish shows up on
the screen of your fish finder.
Knowing the speed of sound in water, which is always approximately
4800 feet per second, helps a fish finder determine how deep the
water is where the boat is located as well as determine what fish
are present in the area.
The fish finder does this by calculating
how long it takes the sound impulse it makes in the water to be
reflected and return back to where it originated. Fish finders
are able to locate fish in water similarly to the way some submarines
have previously been able to locate enemy submarines located in
the same waters.
Fish finders are wonderful tools when you are out fishing in unknown waters, or even places that you fish in often. A fish
finder can take the guesswork out of whether or not there are
any fish around you, and having one can increase the likelihood
that you'll catch a fish.
Knowing how a fish finder works can help you understand how to
better use a fish finder during your fishing trips.
When you go to purchase a fish finder, there are a variety of
different fish finders available for purchase at a vast array
of different prices, for example you may get these best fish finders under 500 dollars or even less than that.
When purchasing a fish finder keep in mind
that fish finders are tools used by professionals, and often have
professional price tags. Think about what features you personally
will need in a fish finder, and then purchase a fish finder that
meets those requirements without breaking your budget.
