Before you spend a dime, make sure you understand how the device works, this will help you know how to use your fish finder.
Remember you can have the very best GPS fish finder combo in your boat but it won't help until you know how to use it.
To begin with, fish finders use sonar to display everything below and around your boat. This unit produces sound waves, and the transducers send the signals through the water.
As the signals penetrate deep in the water, it spread in the form of a cone. When the sonar hits an object, the signal is sent back to the transducer.
The computer then calculates the time between when the sound was sent and when the feedback was received to locate fish, determine bottom structure and depth, and displays it on the screen.
The fish finder market today is flooded with countless fish finder brands, models and a variety of types. On top of this, technology has taken the fish locator market by a storm, with some devices enabling more features than others.
Not only this, the prices are very competitive, and this also makes the buying process a bit tricky and time-consuming for beginners.
On top of this, a high-quality fish detector is not a cheap device. The good news is that we’ve prepared the following buyers guide to empower you so that you choose the right product without any hassles. Moreover, with our extensive reviews above, you can quickly settle for the best.
A Global Positioning System (GPS) is an essential feature of a fish finder. A GPS will help you locate a fishing ground you previously marked without much effort. Not only this but it will also help you navigate through the waters effortlessly.
With a GPS fish finder combo, you can fish even in new environments and still chart your way home. However, not all fish finders will come with a GPS option, so you need to make the right choice when buying fish finders.
Two devices make up a fish finder: the display unit and the transducer. The transducer is the devices that emit and receives the sonar waves. Without the transducer, a fish finder is just a simple screen that cannot display any data.
Usually, fishfinders come with a default transducer that works pretty well. However, you can purchase an aftermarket transducer if you need added sonar features like CHIRP, DownScan, SideScan, and ForwardScan.
When it comes to choosing a transducer, the cone angle will determine how sensitive your sensor will be. The sonar waves sent by the transducer spreads from one point and widens as they move deeper.
The more the waves extends, the more it loses their sensitivity. A top-rated fish finder is the one with a narrow cone angle as it can go to deeper heights and remain sensitive.
The display of your fish finder is crucial. A black and white screen will function well, but a color screen is more appealing and gives precise details of different types of fish available. Also, you may need to check the size of the screen.
A larger screen is better as it provides wider viewport. This helps you interpret and distinguish between different features under your boat. However, note that a larger screen may cost you more.
In most cases, this functionality will come built in the GPS. It will help improve your fishing efficiency as you will know whether you’re trolling at the right speed for a particular type of fish.
Power is an important consideration when choosing a fish finder. In a depth finder, power is measured in watts. A good fish finder should be powerful enough. High wattage means the device will show faster and accurate readings.
The best fish finders have a minimum wattage of about 600 watts. However, power will also depend on the depth of fishing; shallow water requires less energy compared to deep waters.
When looking for a high-quality fish finder, the level of experience and boat ownership will determine which device is right for you. If you are a pro, a fixed fish locator will be more suitable for you as you can mount it on an ideal location in your boat. However, if you don’t own the vessel, then a portable unit is a perfect choice for you.
Price is often related to value. Many anglers believe that expensive devices are the best. This is not the case; the best fish finder is one that you can use with ease, and give you a remarkable performance.
Some of the expensive devices are of poor quality and not up to the task. Consider your budget and choose what works best for you. After all, it is all about satisfaction and getting more fish.
Having to lead you through our top 11 fish finder reviews, buyers guide and finally educated you on how it works. We believe that you can comfortably compare and contrast the options to get the very best fish finder for your buck.
The final decision on what to buy depends on you, but with the knowledge, you have gained so far will help you make an informed decision. One thing you can be sure of is that the units reviewed here are absolutely among the best fishing sonars on the market. So get one today and experience the magic of a huge catch!
