Fishfinders use transducers to send out sonar signals and such signals bounce back with a reading estimating the depth of bottom, any vegetation or fish found at the time of the reading. Many fish finders use more than one frequency to provide you a better view.
Higher frequencies provide a narrower cone angle with perfect details while lower frequencies provide higher depth penetration but it will limit sensitivity when the range becomes longer. You need to have some knowledge about how to read and interpret these fish finders if you are hoping to use one. It might be a bit confusing at the beginning but when you get used to it, you will be able to fish like a pro in no time.
How to Install?
Most of the fish finders are not complicated and can be easily installed with minimal technical knowledge. Portable fish finders are especially easier to use. All you have to do is just switch it on and do your reading. If you have a fish finder that is not portable, you have to install it from land and attach it to your boat using the mount which comes along with the fish finder.
How to Use the Fish Finder?
Even though every fish finder works slightly different, the setup is basically the same. You can do more with your fish finder than just locating fish. Most of the fish finders come with GPS facilities and such fish finder GPS will help you to return to spot at a later date and track where exactly you have been.
Fishfinders measure the depth of the water, it will show you if the water is getting shallower and also any objects detected underwater which you have not been aware of. This technology will help you detect hazards earlier and it’s very unlikely to get lost in the waters when using a fish finder with GPS so it will also guarantee your safety.
There are side imaging fish finders that simply show you what is there in the sides of your boat including what’s underneath. These types of finders have a certain type of transducer which will emit two sonar beams to either side of the boat. This finder will allow you to see far more than what the traditional fish finders would show you by providing a detailed image of everything around you.
It will be hard for you to determine what the object is just by looking at the image from a normal fish finder. However, side imaging fish finders will allow you to differentiate between the object as to whether it’s a fish or some other object giving you the chance to catch more fish.
If you are hoping to get more from your fishing experience, using a fish finder is the best option for you. Therefore, you will be able to have fun while fishing instead of wasting your precious time hopelessly wandering trying to find fish.
