Review of The Best Fish Finders of 2019 | ProductIdeaGuide.com

If you are wondering how to make your fishing trips more effective, then you are in need of a fish finder. So we have compiled a list of the ten best fish finders available in the market for sale in 2019.

Have you ever sat with your fishing pole in the water for hours wondering why you haven’t caught anything? Do you want to make your fishing trips more worthwhile? If yes, then we have the perfect product for you: a fish finder. This device will help you locate fish faster and also provide you with other information to make your fishing experiences more effective.

A fish finder is a relatively new equipment that is becoming more and more popular among novice and seasoned fishermen alike. It is an instrument that can locate underwater fish and structures by detecting sonar or reflected pulses of sound energy.

Apart from the location of fish, most fish finders are also able to gather a lot of other information such as water depth and temperature, your travelling speed, the weather and many more. The instrument then presents this information to you graphically in its own display or some fish finders make use of your smartphone/tablet’s display.

There are many brands of fish finders to choose from in the market but if you are new to this device, it will obviously be hard for you to judge which is the superior one. Therefore, we have reviewed many fish finders by analyzing the product and going through the customer reviews and have selected the ten best fish finders.

But before you can ascertain which one of the ten best fish finders is the most suited for you, you need to know what features make up the best fish finders.

  • Transducer

The main functionality of a fish finder comes from the transducer. It transmits sound waves, which are reflected off of underwater fish and objects and are sent back to you in the form of a picture.

Depending on the angle of the cone, you can determine your area of coverage. If you want to scan a larger area, the cone needs a bigger angle. But the larger the angle, the more you lose the strength and the transducer cannot fetch information from a lower depth. A narrower angle can fetch information from the deep but cannot cover areas around you. Basically, if you want information of your surroundings, choose a wide angle and if you want information from deep under your vessel, choose a narrow angle.

In order to choose between these two angles, you need a dual beam or dual frequency transducer. Multiple beam transducers are also available. But do not undermine the strength of a single beam transducer because they can shoot their sound waves to the sides, increasing the surface area of the search.

  • Frequency

The frequency is directly related to the angle of the cone, which we discussed above. Most fish finders have a frequency of 50, 83, 192 and 200 kHz. And some fish finders combine frequencies to make dual or multiple beam fish finders. More frequency means a more detailed result.

  • Power

A higher power makes the fish finder more effective at its job by increasing the depth it can reach and increasing the speed of analyzing the sonar information. If you generally fish in shallow waters, such as lakes, you can make do with a low power. But for fishing in deep waters and for seasoned fishermen, a wattage of 1000 or more is advisable.

  • Display

There are few things you need to analyze for the display because fish finders feature various types of display from black and white to colored. What you need to note most importantly is the pixel size. The larger the pixel size, the more detailed will be the image on the display. And naturally, as the pixel size increases, so will the cost.

A bigger display will show a clearer image with more details and the information will not make the screen crowded.

Some fish finders pairs with your smartphone or tablet using Bluetooth to use that as the display. This can be very advantageous since this will reduce the cost of the fish finder as it does not have to come with a display and it can also produce clear and detailed images on your phone screen.

  • Setting up

If you have never used a fish finder, you will be at a loss after buying it if you do not know how to set it up. Luckily, it is not that hard to install your new device. Every fish finder comes with a manual that will tell you exactly how to program it.

If your fish finder is not portable, you have to mount it on your boat. Many fish finders come with a transom mount. Next thing to do is to turn it on and set your preferred settings. If you do not like the pre-programmed settings, you can customize it however you want. This includes choosing the fish ID settings, depth settings, etc.

  • Additional features

These days fish finders are not only limited to locating a school of fish. They are made more versatile, for example with a built in GPS. The GPS can pinpoint your exact location so you can sail out to the ocean but the GPS will remember your location relative to the coastline. Furthermore, the GPS can also help you mark hot fishing spots or waypoints and come back to them later. Normally, you can save hundreds and thousands of these waypoints in a single fish finder.

The best fish finders should be able to provide you with more information such as the weather, your vessel speed, etc. It should also function as a depth finder. Fish finders that use the phone or tablet as the display come with a free app that features such information. This helps you plan out your fishing trip so you can make the most of your day.

Now that you know what to look out for, here is our pick for the best fish finders of 2019:

The Raymarine Dragonfly 7 Pro CHIRP Fish Finder is what we are going to review next on our list of the best fish finders. This device also has a ton of features you will find useful.

Firstly, it has a stunning display with optical bonding LCD technology. With this you can see your image or data in bright colors, sharp contrasts, and crisp result. The display will also not fog up in cold mornings and you can see the display quite clearly even under direct sunlight. You will also be impressed by the photograph like images that the fish finder will produce of the objects and fish under your boat.

Like most top notch fish finders, the Raymarine Dragonfly 7 Pro also works in both fresh water and salt water up to a depth of 600 feet.

The in built GPS system can map your routes and the high speed bottom tracking will help you dodge obstacles when you are sailing on shallow water.

This fish finder has a new feature that the previous ones we reviewed so far did not have. It has a built-in Wi-Fi, enabled via the Raymarine Wi-Fish mobile app, that can stream your data to your smartphone or tablet in case you want to view them later.

Compared to the iBobber or the Deeper fish finders, this one is heavier at 9 pounds but you have to remember that this also has its own display and is not dependent on your phone. You can mount it easily on your boat and you’ll find that operating it will not require you to study the instruction manual extensively.

This fish finder utilizes the CHIRP technology but unlike most similar fish finders, it does not cost a fortune. You will be astonished how simple and easy it is to use this fish finder. Just plug it in and use the few buttons to set the controls and that’s it.

If you are familiar with fish finders, you will find that with the Raymarine Dragonfly, you are able to locate and catch more fish than before. This is because it covers an extensive range that can locate even the smallest group of the smallest fish.

The Navionics chart will ensure that you are not lost even at night when it’s foggy. It helps you track your position relative to the coastline. It also lets you mark waypoints that will guide you back.

But even this great fish finder has a few drawbacks but none of them are big enough to be a deal breaker. For instance, since the display does not have backlight, you need a flashlight or another light source to see the screen in the dark. It also takes a bit of time to turn on and also to turn off. And since it is not possible to turn the Wi-Fi off, it does drain the charge faster. So when you are not using the device, it is best if you turn it off immediately to preserve battery life.

Pros

  • The superior transducer has a temperature sensor
  • WiFi enabled to stream sonar data
  • Improved target separation

The last fish finder in our list of the best fish finders is the Lowrance  Fish Finder Elite 3X. This reasonably priced unit displays your information with a greater detail.

The display is colored and has LED backlight so you can see the display even in the dark. You can easily see the screen from any angle with the pixel resolution of 240 x 360. You can adjust the backlight with the power button to switch from daytime to nighttime viewing.

The dual frequency Broadband Sounder transducer emits an 83 kHz sonar that focuses on a 60 degree area and the 200 kHz sonar scans a 20 degree area from where it can gather more detailed information. It can tell the difference between a solid object and a soft object and create vertical displays. When it finds fish, it depicts them as arches or fish on the display. You can set your preference in the visualization option. You can quickly switch between the two frequencies using the Page button.

The transducer provides some additional information such as water depth and temperature and the speed of your vessel.

There are options that lets you zoom in and out to focus on a targeted area. Moreover, there are also alarm and tracking settings.

Advanced Signal Process-or ASP minimizes the need to adjust the Elite’s settings manually. More important Menu button-provides access to sensitivity, range, frequency, noise reduction, ping speed, color line, fish I.D., overlay data and settings pages.
