Fishing has evolved drastically over the different paradigm shifts that this world has endured. One quite gracefully doesn’t have to use spears like the early cavemen nor do people have to sit hours and hours beside the pond present in their ranch to catch fish based completely on a vague principle of uncertainty. And one question which always bothers any fisher is how to catch more fish? 

Best Cheap Fish Finder

A Sounder or a Fish Finder device is a skilful instrument manufactured to pinpoint the geographical location of fish underwater by using the technology of detecting reflected pulses of sound energy, which is an established formula in the working of a SONAR.

The modern-day fish finder device has a display, which illustrates the measurements of the reflected sound allowing the operator to analyze the information to locate the colony of fishes, underwater debris, etc.

These effective instruments are used both by the commercial fishermen and people fishing for a sport. Technological advancements in this sector have allowed a more comprehensive view, which is the result of an integral amalgamation of the GPS, fish finder system, marine compass, and radar systems.

Therefore it is important to buy the best fish finder under 500 available in the market.

The fish finder is a very important device and should be evaluated by the features it has to offer along with a suitable price range.

Your Guide to Buying Fish Finders! 

Heading out to a market or an e-commerce site and picking a fish finder without a comparative knowledge of certain factors which are essential for a particular product’s efficiency is equivalent to just chugging your money down the drain and ending up with a diamond which you don’t need. 

If you can’t make any head or tail out of the example provided is the exact reason one needs a buying guide which offers analytical insight into the provider you wish to purchase so that instead of rash move, you make a well-informed decision.

Now the discovery of the Fish finder has been a huge breakaway in the postmodern world and it has justifiably eased things for fishermen by reducing the uncertainty factor in the practice of fishing by a huge margin.

However, with every innovation there are advancements and the Fish finder has also evolved with greater specifications and features with every new update in the field. 

The important part here is what you need in the Fish finder and just searching the best budget fish finder on the web won’t do any justice to it. Now the purchasing power lies with you at the end of the day but here are some parameters through which you can evaluate your decision and by doing so find the perfect fish finder suited uniquely for your needs.

1. Transducer:

It is a device that transmits sound waves and then again receives them. They are a crucial part of a fish finder. These waves emitted by the transducer into the water bounce back off various objects and when they come back it is processed as images and information on the screen. Now the main thing concerning them is the material and the type of mounts. 

install a fish finder transducer

The transom mount is the easiest one to install when for a bigger boat you might need a thru-hull mount. Coming to the material, for casual users fishing for sport plastic housings would do enough. Bronze housings are bigger boats with fibreglass or wooden hulls. 

2. Screen and Resolution:

Garmin Striker 4 Display

Here the main debate is between HD colour screens and conventional black and white screens. We would always advise for a colour screen because the data is illustrated better and has a refined clarity, thus it is easier to understand. Black and white screens are really difficult to read under dark skies but if you can’t afford a colour screen fish finder, a black and white screen is still a good viable option available. As for resolution, one should at least aim for a 240 x 160-pixel screen; higher pixels are recommended for crisp images. 

3. Resistant to Water:

You must buy a device, which is water-resistant because without that it just kind of defeats the whole purpose. The better resistant the device the more durable it is.


Q1. Does the Fish finder come with a screen cover?

Answer: It varies from brand to brand but generally one has to buy a protective screen cover after the purchase of a fish finder.

Q2. What is the need for an SD card in a fish finder and why is it important?

Answer: The SD card serves the same purpose it serves in other devices that is the storage of data and information. With the help of this function, one can store the marked spots, past trails, and waypoints for future use again.

Q3. What powers the fish finder?

Answer: There are two types of power sources namely external batteries or inbuilt rechargeable batteries. In the case of built-in batteries, a charger is usually provided along with the fish finder.

Q4. Can the fish finder be mounted on the boat?

Answer: Most of them can be mounted on the boat or kayak with accessories, which are usually provided in the entire package of the fish finder. In other cases, you have to buy the additional accessory to mount them to your boat.

Q5. What is the easiest fish finder to use?

Answer: To pinpoint to a single fish finder like that would be an injustice to all the others present but comparatively the Lowrance Hook 4x Bullet is quite easy to install and use and offers a comprehensive view of the fish colonies and the allied structure.
