A Fast and Comprehensive Guide to the Best Fish Finders
Do you want to go fishing? Are you ready for hours of waiting for that awesome catch? If not, then save time and enjoy fishing more by using a fish finder.
What is a fish finder? This is a device that provides help when it comes to searching and tracking fish beneath the water. It makes the whole procedure and hobby of angling faster and easier. The ability to track down fish is helped by the various features and functions that make up a fish finder. In this article, we are going to discuss how the whole thing works.
The fish finder is an electronic device and this means that it requires electrical power to operate. The amount of power determines the depth range of the fish finder. The deeper the water is, the more power is needed in order to meet the demand of such depths. A unit that can deliver a hundred watts can go up to a depth of 600 feet while those that deliver over a hundred watts can take on as much as 1,500 feet.
Once an electric impulse is produced, the transducer will then take over and do its job. The transducer transforms electrical energy into sound energy. This sound energy is then transmitted through the water with the help of Sound Navigation and Ranging or SONAR technology. It has the ability to reflect audio beams beneath the water to track fish within the vicinity together with several other details like weeds, rocks and sand. Depending on the capacity of the transducer to produce a single or several beams, these reflected beams will differ.
Following the strengthening of signals, the details are now ready to be shown. Users will then view and acquire all the gathered information on the display by means of the provided Fish ID icons which are translated in arc forms. However, they might not show up visibly due to mediocre sensitivity conditions.
To maximize display activity, users may have to look for the best fish finder with an excellent LCD monitor that has plenty of pixels. Image resolution differs depending on the pixel capacity; so the higher the pixels, the better the resolution.
Users can also search for water details like temperature, depth, range, salinity, and other related things. All of those mentioned factors are crucial when it comes to finding your target. Keep in mind that the best fish finder can only provide assistance—like any other device, it will still need your input.
Selecting a Fish Finder
Fish finders utilize a certain kind of technology called SONAR which stands for Sound Navigation and Ranging. It is composed of 4 components: the transducer, transmitter, display and receiver. SONAR operates by conveying an electric impulse from the transmitter and transforming it into a sound wave by means of the transducer, which in turn sends the sound wave under the water.
As soon as the sound wave hits an item, it bounces off of the item and conveys this reverberation back to the transducer. The transducer then transforms the reverberation back into an electrical signal. The receiver boosts this signal and transmits it to the screen to show users the gathered information.
Plenty of beginner anglers or fishermen who want to take advantage of a fish finder often ask how they should choose a model that will fit their preferences and needs.
There are 5 key things to remember before making those buying decisions.
There are two kinds of transducers; single frequency transducers and dual frequency transducers. The former is recommended for lakes and shallow fishing spots while the latter is meant for deeper fishing locations. Dual beam transducers are the same as dual frequency so do not get confused.
Overall, the higher the power of a model, the more effective and efficient it will be. High-powered models are more expensive and should be considered an investment. You can save up and opt for a high-end unit if you plan on angling and fishing for a long time. Keep in mind that high-powered model can still provide users with excellent imaging even in shallow water.
The depth that a fish finder is capable of is related to the quality and the power of the transducer. Expensive models can get through the water in a more effective manner.
Remember that the depths that are provided in the product’s specs are targeted for clear water. Dark and salt water can limit the depth that the SONAR can get through.
To be safe, always buy a fish finder model with a depth range of around 10 percent higher than what you needbecausea higher depth range will help the unit in dark or salt water environments.
Fish finder displays range from 4 to 7 inches. Several models are even bigger than those dimensions. A bigger screen of course means a higher price. One benefit of a bigger screen though is the data on the screen can be easily read even under glaring sunlight.
The screen resolution refers to the clearness and clarity of the image. Higher resolutions mean better images. If you want a fish finder that can handle bright sunlight, opt for color screens since they are easier to read. Then again, higher resolutions mean a higher price tag.
Now that we are finished with the common factors, we will now discuss some advice on how to select the best fish finder.
Choose the best quality fish finder that your money can buy. Of course, the budget you allot for this piece of technology is completely up to you.
Next, think about the locations where you plan to fish the most often. Do you plan on taking your hobby to coastal areas or lakes? Do you plan on utilizing the fish finder on your own boat, or will you depend on rentals every time?
The answer to these questions will often let you know if you are in need of a fish finder that can be fastened or one that requires drilling, or you need a model that will work best in deep water or shallow water.
If you are in need of a fixed-mount model, you will then decide whether you need a hull transducer or a ransom mount transducer. If you want something more affordable and easy to install, you may opt for a transom mount transducer. You can buy one in dual or single frequency units. However, keep in mind that they operate best in calm, steady water and are inefficient at over 10 knots.
Hull transducers are recommended for their performance and better clarity, but they can be a challenge to install and they are far more expensive. For precise readings though, a hull transducer with a dual frequency is recommended for offshore fishing and fishing in deep, freshwater locations. Hull transducers also respond well to high-speed fishing.
What About GPS Fish Finders?
Fish finders may sound too good to be true so you might expect there to be a catch. However, you do not have to be concerned about this since they have proved to be a big help to top anglers and fishermen.
Some may say that these units are quite pricey but all in all, they are great investments especially if you fish for a living or are a proud angler. These days, there are fish finders available with GPS technology. In terms of GPS fishing, the performance is different from common GPS units, but the mechanics involved are quite similar.
GPS has a group of maps that typically manage a wide location, like for instance continents. The technology presented by GPS offers all of the information for the majority of widely-used fishing areas. Apart from distinguishing fish, SONAR technologies are utilized and several can distinguish other items underwater like weeds, rocks, and other nautical creatures.
GPS fish finders are recommended for individuals who are still in the planning stages of their angling/fishing expeditions. It makes all of that location planning easier since all users have to do is download the current maps and location information to check on fishing spots that are close by.
The map will get users covered regardless of the location of the fishing spot whether it’s a lake, coastal area or a river. These GPS models include a feature that allows users to save locations so they can return to the same spots for fishing.
GPS fish finders also show thermoclines which are efficient when it comes to plotting areas that have warmer or cooler water temperatures. These fish finders with GPS are the real deal and they can provide users with helpful results as soon as they are familiar with its workings.
