Things to Consider

How to make the most out of your fish finder

Wireless connectivity

Best Fish Finder under 500
While you can connect most fish finders to your tablet, desktop computer or tablet via USB cords, the best models such as the Garmin Striker 7sv and the Raymarine Dragonfly 7 Pro Chirp Fish Finder enable you to connect using Bluetooth or Wi-Fi technologies. This gets rid of the need to utilize any sort of hardware to transfer data, thereby making the procedure seamless and quick. Apart from moving data from your fish finder to your phone, Wi-Fi also allows you to use some fish finder-compatible apps on your smartphone.

GPS system

Numerous fish finders nowadays boast GPS capabilities, which is a highly useful feature, especially for people that have a tendency of fishing in large lakes and oceans. The GPS system can help you to navigate your way back to the coast easily. The GPS system can also be utilized to save prime spots’ locations so that you can easily return there later. You can also use the GPS system to map favorite places and even track hazardous areas in the water.


If your device has a multi-screen feature like the Humminbird Helix 7 Sonar G2, you are in for a really great time. This function enables you to divide your display, showing two or even more features simultaneously. This function is especially useful when trolling as it allows you to see the bottom and the map at the same time. Some models can even display different bottom views while fishing.

Features to consider while choosing a fish finder

Best Fish Finder under 500If you really want to select the perfect fish finder for your needs, then you must take some factors into consideration. Below are some of the most critical features you must look for.


A premium-quality display is capable of helping you to detect small details that may be missed otherwise. Besides, a good display is capable of improving your overall fishing experience since you don’t want to squint at your screen for the whole day. In general, you need to look for the largest display you can afford and one that’s sealed to avoid fogging.


The higher your fish finder’s frequency, the more the details that will be sent to your display. While higher frequencies are most effective in shallow waters, deep-sea trawlers and commercial anglers often utilize low-frequency transducers.

The most common frequency range is from 50 KHz to 200 KHz, and the latest fish finders come with several frequencies so that you can either use them simultaneously in split-screen mode or be switching back and forth between different frequencies.

Side view

SideScan sonar allows you to scan large amounts of water at once. The average model will be able to scan about 100 feet to every side efficiently. Also, you can easily scan regions without causing any disturbance since you don’t have to go over the areas directly in order to scan them. The shortcomings are that these aren’t as effective in deep-water fishing. Averagely, things start getting blurry when you go as low as 75 feet. At that point, you will begin to notice a drop in the image quality. The Garmin Striker 7sv is one of the models with side-view capabilities on our list.

GPS capabilities

The best models usually come with GPS capabilities. Of course, it doesn’t make any sense to buy a separate navigating tool when you can have both fish finding and navigation in a single convenient device. GPS-enabled models allow you to store areas where you were previously successful, and they can be used to mark sports with submerged obstacles. Examples of models with GPS capabilities on our list are the Lowrance HOOK2 Fish Finder and the Humminbird Helix 5 Chirp GPS G2.


You must also ensure you get the right size for your needs. Generally, you need to acquire a unit that is adequately large to make reading easy.

If you choose a model that is excessively small in size, differentiating between your target and other water debris will become a problem, which will invalidate your original general purpose of owning a fish finder. Also, the device should be compact to store it conveniently among your other fishing gear essentials.


By now, everyone ought to have already known the importance of getting a warranty when buying things. Electronic devices, in particular, are very risky to buy without getting a warranty as they have a tendency of becoming faulty anytime. Hence, before you choose a specific model, check its warranty terms first.

Extra features

Best Fish Finder under 500You also need to look for extra features like Wi-Fi connectivity to be able to connect your fish finder to other devices and use the specialized applications; split-screen feature to use all the possible modes simultaneously, and preloaded maps to navigate easily. However, keep in mind that every fancy feature you have on a fish finder will add to its overall cost in one way or the other.


The side view feature makes fishing a lot easier. It allows you to have a greater side-to-side range to mark fish. Since side view enables your fish to finder to scan two directions simultaneously, you are able to quickly scan more water, and therefore make your whole fishing experience more successful.

Most fish finders made nowadays come with a MicroSD slot, for good reasons. With a MicroSD card, you can store hundreds of navigation routes and waypoints on your device. In addition to that, some models come with actual SD cards which are packed with preloaded maps.

While you may find fish finders that are water resistant, we don’t think a fish finder can be waterproof. Most of them can withstand light rain and occasional water splash, but none of the models on our list can withstand full submersion in water.

Our Verdict

Every fisherman deserves reliable fishing tools, and there aren’t many fishing tools that are more reliable than the Raymarine Dragonfly 7 Pro Chirp Fish Finder. Despite being priced at less than 500 dollars, the device has most features you’d find on high-end models, including a large display, Wi-Fi connectivity, and a MicroSD slot. It is our pick for the best fish finder under 500, and most users will agree with us.

Not many companies are as big as Garmin when it comes to the manufacturing of fishing equipment, and their exceptional brilliance can be clearly seen in the design of the Garmin Striker 7sv. With its side-view capabilities, Wi-Fi connectivity, compact nature, and waterproof casing, this model deservedly takes the second spot.

It’s quite difficult to find a fish finder that is budget-friendly and at the same time functional, so it’s a little wonder that Humminbird has managed to seamlessly combine both in the Humminbird Helix 5 Chirp GPS G. Despite being very affordable, the unit has an inbuilt GPS, a MicroSD slot, and a split-screen feature.
