1. Lowrance Hook Reveal 5 000 15500 001 Fish Finder Best Fish Finders Under 500

When considering the best quality fish finder, you simply must talk about Lowrance. The company has an ambitious goal of changing the fishing technique. The Lowrance Hook Reveal 5 Splitshot is one of the best fish finders under $500 overall owing to its full feature set and accessible price point.

It’s not far different from the same year’s Hook Reveal 5 Splitshot Xdcr but offers two dominant extra features. First, it helps you quickly find and locate the fish. And the second is, the noise Rejection system and auto-tuning sonar make it an incredibly well-rounded choice for most anglers.

You will get high-detail maps of almost 4,000 US inland lakes. You can also create custom contour maps with even greater detail over any map or GPS plotter with Genesis Live (Genesis Live is a real-time mapping feature), so you can get onto the fish faster. It has a GPS speed function so that you can calculate the speed of your boat based on the GPS input.

The auto-tuning sonar automatically adjusts settings as fishing conditions change and the 5-inch crisp display delivers clear views no matter the conditions, even in direct sunlight with excellent clarity. Lowrance Hook Reveal 5 fish finder also has an internal temperature sensor.

This device includes the SplitShot transducer, which is plastic and features a transom mount and trolling mounting possibilities. It supports multiple frequencies, including 50/83/200 kHz for standard CHIRP sonar, and 455/800 kHz for DownScan. It was designed for lake fishing or inland fishing. However, you can use off-shore in areas with shallow waters, or you can opt for an extra 50/200 kHz skimmer transducer.

It has a coverage of 40° and a maximum depth capability of 1000 ft. (305 m). It is one of the most advanced Fish Finder Combos under $500 from Lowrance without having networking features. Therefore, because of the lack of Ethernet and NMEA support, you cannot use external GPS. However, you need a bit of knowledge to operate, but nothing too difficult if you’re familiar with this type of device previously.


  • Looks great with 2D Broadband Wide CHIRP Sonar
  • Fast and accurate GPS with Genesis Live real-time mapping
  • Adjustable backlight for superior readability
  • Bracket mount and panel mount kit included
  • Easy-to-use interface and easy to install
  • We like the GPS function which indicates the place but also the time to get there

Buyer’s Guide: Best Fish Finder Under 500 Dollars

Here’s an in-depth buying guide to help you make an informed decision:

Depending on your fishing habits

Not all fish finders are created equal, depending on where you are fishing. For example, if you are used to sea fishing, you will have to opt for a sounder displaying 50 / 200Khz, while for freshwater fishing, favor an 83 / 200Khz device. This is often specified on the product sheet to facilitate the purchase.

Choose a good screen size

Display is very important for fish finder since makes it possible to read the data found by the probe. It must therefore be large enough for unobstructed views. The definition of images, but also the ability to adapt to sunlight or on the contrary to a gray sky are essential.

Some displays show additional information for different areas. However, it still depends on the functions of the device. Many fish finders give you the depth and temperature of the water. You can also find information about battery status, signal range, or active features such as the fish alarm on the screen.


Resolution is crucial because it directly impacts the clarity and detail of the images you see on the screen. Higher resolution means clearer images. Look for at least 480 x 480 pixels, though higher is better.


Transducer is an essential part of all fish finders because it sends and receives the sonar wave messages. When the waves are emitted into the water, the principle is that they bounce off any object they encounter. These objects are then picked up by the transducer. This data is usually transmitted to a central unit where it can be processed and turned into a visual analysis of what is happening underwater.

Transducers come with different types of brackets to install. They are usually made of plastic and are easy to assemble and disassemble and are compatible with almost all types of boats.


This common thing is applicable for fish finders, higher power is better than lower. But if you only intend to fish in shallow water, low power won’t be a problem. However, the high-power models bring some advantages, for example, the faster these sound waves and the more accurate the reading you will receive. If you regularly go fishing in open saltwater or a large body of water such as a large lake, a more powerful model will be better.

Additional functions: technology

Fish finders are above all maritime accessories intended to locate fish. It was without counting on the expectations of the consumer. So, if this function is not sufficient, look at the on-board technology. Does the device act as a GPS, can it memorize the places where fish evolve in whole schools? Obviously, these functions often drive up the purchase price.

Ease of use

Just because it is hard to understand, a high-end fishing finder can be a product. The important thing is helpful for you to easily master this device and enhance your fishing trips. Make sure your device is lightweight and easy to carry. Some models also include carrying bags.

The price

There is some disparity between the different fish trackers. If the brand can raise the price, we often pay for the presence of advanced technology. However, before making an expensive purchase, ask yourself how often you will use this device and the functions that are most useful to you in order to decide on the most suitable device. If you prefer GPS as part of a fish finder, you will certainly find it on the market in the higher price ranges.


Are all fish finders waterproof?

Not all fish finders are waterproof, but the majority of famous brands always offer that. On the other hand, some may survive splashing, but not adequately submersion.

Which fish finder is good for ice fishing?

The short answer is Dual Spectrum CHIRP Sonar. However, it is entirely possible to use both hand-held and mounted sounders for ice fishing. Keep in mind, the cold temperature ruins the transducer easily if you choose a cheap fish finder. So for ice fishing, we always recommend investing in a high-quality model.

What is CHIRP technology?

CHIRP stands for “Compressed High-Intensity Radar Pulse”. Echosounders with CHIRP emit different waves. Ultrasonic tones have differentiated frequencies – like a bird – in order to get the clearest data possible. Using CHIRP technology, the encoder can analyze each returning wave and transmit detailed results to the visual display device. CHIRP technology is therefore suitable for professionals or even beginners who want to collect as much information as possible.

How to evaluate the data correctly?

The image of the data display device is generally divided into three regions. The uppermost region shows you the surface of the water as a line, just below you can sometimes see marks that represent water disturbances because of winds or the movement of the boat. The upper area is not that important to you as there are hardly any fish in the area.

The middle region represents deep water, which is much calmer and therefore easier to read. In the area, the fish finder shows you possible objects. You will usually also receive information about the size of the object and how deep it is.

The third and final level gives you the metro. You get a good cross-section, although the promising devices tell you something about nature. For example, if it is a hard stone floor, the sonar will find information and indicate that the area is very dark. On the other hand, if the ground is littered with plants, the screen displays light-colored ground.

What is the difference between Down Imaging and Side Imaging in a fish finder?

  • Down Imaging: Down Imaging provides a detailed view directly beneath the boat. It’s useful for identifying structures, contours, and individual fish that are located directly below the transducer.
  • Side Imaging: Side Imaging offers a wide, detailed view of what’s on either side of the boat. It’s excellent for locating fish, submerged objects, and structures that are to the sides of your boat.

Do I need to maintain a fish finder?

Yes, because regular fishing can quickly leave residue on the encoder. The data display device is also contaminated with frequent use. For this reason, you should clean your fish finder with lukewarm water after each use. Use only a little detergent for stubborn dirt and do not use harsh cleaning products. Otherwise, the electronics could be damaged. A microfiber cloth is suitable for drying so that no stripes appear on the screen.

To ensure the proper functioning, protect any open jacks or connections. Use wax or grease for example to cover vulnerable areas. In this way, no water can enter and sensitive places are secured. If you don’t need your device for a long time, store it in a dry place to protect it from light. Extreme cold or heat can permanently damage electronics.

If you use the fish finder in the sea, it is necessary to take extra care of it. Because of the saltwater, corrosion can occur more quickly and the material is also attacked by the high salt content.

The Verdict

Fish finder contributes to the joy of fishing. Whether you are an amateur or an experienced fisherman, a good fish finder is an ally for going out to meet fresh or saltwater fish. We spend a lot of time doing research to make this list accessible to everyone. Also, to make this list unbiased, we made sure that none of the experts we consulted were part of any brand.

You now have all the latest data on how to choose the best fish finders under 500 dollars. So pick the one that will allow you to fish more. Keep in mind, not all detectors will give the same results.
