Buyer’s guide: fish finder under $500

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, you will have to favor an 83 / 200khz device. This is often specified on the product sheet to facilitate the purchase.

Choose a good size screen

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 also essential to find the best fish finder.

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


The 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, and 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.

The 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 finder, higher power is better than lower. But if you only intend to fish in shallow water, low power won’t be a problem. 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 salt water or a large body of water such as a large lake, the more power could 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 a marine chartplotter is hard to understand doesn’t make it a good product. The important thing for you is to easily master this device to 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.

Before making an expensive purchase, ask yourself how often you will use this accessory 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 sounder for ice fishing. Keep in mind, the cold temperature ruins the transducer easily if you choose a cheap fish finder. So for ice fishing, always recommend investing on a high-quality model.

What is CHIRP technology?

CHIRP comes from English and stands “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 correctly evaluate the data?

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 due to 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 also tell you something about nature. For example, if it is a hard stone floor, the sonar will find information indicating the area as very dark. On the other hand, if the ground is littered with plants, the screen displays a light colored ground.

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 the sonar unit 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 of your fish finder, it is recommended that you 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 protected from light. Extreme cold or heat can also permanently damage electronics.

If you use the fish finder in the sea, it is necessary to take extra care of it. Due to the salt water, 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, fish finder is an ally for going out to meet fresh or saltwater fish. In order to offer you unbiased buying guides, I test and compare different products and select only those which have an excellent quality.

You now know how to choose your fish finder and pick the one that will allow you to fish more. Not all detectors will give the same results.
