How to choose the fish finder under 300 dollars

As you have already learned from our reviews, fish finders have significant differences. Therefore, you have to purchase a device that is adapted to the use and your ideas and skills. After reading this guide, you will be able to figure out all the important things to consider when buying a cheap fish finder under 300. 

The depth

For each model of fish finder, the manufacturers state what depth it will be worked and how much good data it will be presented. For example, if you are fishing in shallow water, you don’t need a professional device that works at a depth of 100 meters. On the other hand, if you visit the sea regularly and would like to go fishing at great depths, then you should pick up the appropriate equipment.

In the end, you need to know what depth is optimal for you. If you are more of a fishing novice, find out the depths of waters you want to visit before buying. Because it would be disappointing if you buy a shallow depth fish finder and ultimately it doesn’t work in your favorite water.

The frequency and type

The frequency is automatically related to the quality of the image that will provide your fish finder. Because the more sound waves a device generates, the more detailed information is possible to show.

The most common models work between a frequency of 50 and 200 kilohertz. Fish finders above the value are much more accurate because they send out more waves in a very short time period and you get more details data.

The type of fish finder and the associated broadcast cones play a major role in this context. If the frequencies are very high, the device is suitable for deep water, but only registers a small area. With several cones with a beam angle of 60 degrees, wider areas can be scanned, but the image is rather blurred due to the low frequency.

If you want to benefit from both methods, opt for a system with dual-beam. In this way, you can fish in both shallow and deep water and use different frequencies. On the other hand, if you only want to hunt in deep water, the single beam is much better. If you already know that your place of operation only consists of shallow water, then you should prefer systems with Tri or Quadra Beam.

The performance

When you buy a fish finder under $300, you sometimes get an indication in watts. The number tells you the transmission power, which is crucial for good work. We have already mentioned that the higher the power and therefore the wattage, the better results you will get.

At that moment, resort to a fish finder that is between 500 and 4,500 watts. Particularly high-quality fish finders have a transmission power of up to 4,000 watts. However, it should be clear to you that the more powerful the devices are, the more expensive they are.

Underperforming fish finders sometimes have significant problems adapting to the respective conditions. So they can already be unsettled by plankton, waste in the water or currents, and give incorrect information to the data display device. As a result, you cannot distinguish fish from other obstacles.

Not only objects but also the nature of the water can influence the data. For example, the emitted waves pass through saltwater much more slowly. If you have no such setting options or if the sensor does not automatically perceive the properties, incorrect results can be expected.

Good performance is preconditioned, especially when fishing in cloudy waters. Otherwise, the fish finder can be confused by small plant parts, which leads to inaccurate results. The device may even show you fish, even though it is only algae.

The display

The display is the most important source of information, which you need to read and understand frequently. There are big differences in the various models in terms of resolution and display. It almost goes without saying that the data is easier to understand if you get a pleasant picture.

Fish Finder Function

Apart from that, there are fish finder displays that present the information in colors and others only work with black and white. This is reflected in the price. However, beginners should choose color displays because they are easier to read and understand. Adjustable brightness can be helpful on the water in sunny weather.

The functions

Not every fish finder has the same functions, so you should inspect the different models and find out about the possibilities. For example, the system side imaging is integrated with some devices, which enables you to have a side view of the underwater world. In this way, you will discover schools of fish that are some distance from the boat. Such cones, which only point downwards, would not perceive such fish.

Some fish finders under 300 dollars are equipped with a GPS so that you can save a spot with lots of fish and quickly find it the next time you go fishing. The device stores distance traveled and enable you to analyze them after your fishing trip.

Apart from a higher success, a GPS offers more security, for example, in an emergency, you can share the coordinates so that the coast guard can find you. But even shallow spots are easier to remember so that you can avoid the dangerous places the next time.

Some devices already have stored map material for certain regions or countries. For example, if you only want to catch a specific type of fish, the map can show you in advance where you can find suitable spots with the right depth. But the map also knows dangerous places – for example because of its shallow depth – before you leave, so that you are in turn safer.

Another function is the fish alarm so that the device sends an alarm as soon as the encoder registers fish. This allows you to take the fishing trip a little more relaxed and not keep staring at the device. You will be informed immediately if there is something worth seeing on the display. This should not be confused with the depth alarm, which you can usually define yourself.

Water temperature

Many fish finders under 300 can give you the water temperature, so the sensors are equipped with an additional sensor. The temperature can determine success and failure because every fish prefers a certain water temperature for food consumption. If the water is too cold, the metabolism of the scaly animals is automatically reduced so that the fish do not want to eat.

Some species bite better in warm and others in cold water, whereby a temperature of 8 degrees Celsius is usually a prerequisite. If you are interested in certain types of fish, a temperature sensor is a crucial function.

The manufacturers are constantly developing the fish finder so that the new devices come with even more functions. You need to know which functions you really need because the variety of options again reflects the price. If you buy devices from well-known brands, you will be noticed when they released new features.

The technology

You can eject some donors with the fishing rod, and others must be firmly attached. Both options have their advantages and disadvantages, depending on how you use them.

An ejection sensor is suitable for shallow water or for fishing from the shore. The encoder usually establishes a connection via Bluetooth or wireless to the data display device or smartphone. In this way, you can use the fish finder anywhere. With a fixed transducer, you have to mount it on the boat and you cannot fish with it from the shore or on another boat.

The sensor requires more transmission cones because otherwise; the area covered is too small. You don’t normally fish directly under the boat.

Power supply

The power supply is an important purchase criterion you have to consider. Most fish finders on the market use a small battery as a power supply. The same applies to the data display device, although a battery is rarely installed. Find out in advance how long a battery charge will last.

If you want to spend the entire day on the water, the battery must last at least 6 hours. You should always have spare batteries with you, but it is annoying if you have to replace the batteries three times a day. Stationary models, which you have to connect to the boat engine offer an alternative.

When using a fish finder, always make sure that both the transmitter and the visual display unit are closed properly. In the worst case, water penetrates and damages the electronics so that the device is no longer functional afterward.

The dimensions

If you decide to start fishing, lug a few things like a fishing rod, bait, survival knives and other accessories. So it is therefore an advantage if the fish finder does not have oversized dimensions to make transportation easier for you.

Many fish finders are already small, but the display device needs the right size. It should not be too large for good handling and not be too small for better recognition. Here you have to make a few compromises in terms of image or comfort if you want a small or large device.

The data display device is ideal when it lies comfortably in the hand and still brings a good and large picture. You can easily attach some display devices to the boat or fishing rod.

The weight

Besides the size, weight is a decisive factor, which should be as low as possible. A light fish finder is helpful for transport or use. If you choose a model to attach to the boat, the weight doesn’t matter. On the other hand, if you mount the fish finder on your fishing rod, you definitely do not want to lift a 3 kg device.

After all, it depends on your use, and what weight you can carry.

The processing

A final criterion is the processing, which is crucial for long shelf life. If you notice cracks, bad transitions or cavities when you buy the fish finder, it won’t serve its purpose for long. Because electronics are installed here, which can break because of the influence of water.

Even the data display device can accidentally come into contact with water so the component should be waterproof and well processed. Therefore, take a close look at the fish finder and check weak points.

Some devices have labels or quality seals, which already give you an indication of high-quality workmanship. Also, well-developed test results are a sign that it is a promising model.

Frequently Asked Questions

How do I use the fish finder correctly?

Each model of fish finder works a little differentiated, which is why you must read the instructions at the beginning of unboxing. Familiarize yourself with the device and study all important information on the promising application. Only with a good understanding you can use your fish finder properly and really benefit from it.

However, despite the differences, some basic functions are the same.

Some fish finder models work to a depth of 100 meters and more. Others can only analyze the environment to a depth of 30 meters because the frequency of the sound waves is too low. With other devices, you have the option of setting the respective frequency. It is important for you to know that a low frequency enables a better overview, but does not provide detailed results.

At a high frequency, you can see small fish occurrences, but the search angle is much smaller, and the overview is limited. A setting with a low frequency is suitable for optimal recognition of the fish. Once you locate fish in a zone, you can examine the area with high frequency.

What accessories are required with fish finder?

Basically, the encoder and the display device are enough for you. The scope of delivery always includes the batteries or the rechargeable battery and instructions. With a stationary fish finder, you may still need fastening material that some manufacturers have already made available to you.

If you want to mount the data display device on the fishing rod, there are special brackets that you have to purchase separately. Otherwise, you do not need any accessories to use your fish finder, as you will receive a device in a set with all the important parts.

Is there an alternative to fish finder?

No, because no other device can show you what is happening in the water. You can only determine the water depth in other ways for example, a mechanical depth gauge is also suitable. The small accessories can be attached to your fishing rod and operated with the line. As soon as you eject the line and the line begins to sink in the water, the mounted counter begins to locate the depth of the hook.

If a fish bites at a certain depth, the clever accessories let you know at what depth you have to fish on the second try. The mechanical depth gauge makes it easier for you to catch prey, and yet it does not show the fish.

What types of fish finders are there?

Fish finders come in different colors, techniques and from various manufacturers. For this reason, all models differ from each other and yet the focus of each device is on the sensor. Success or failure depends especially on the donor, which is why we focus specifically on the sensor for the species.

You need to know that each transducer emits the sound waves into the water in a certain cone. For a simplified introduction, you can compare the transmission cone of the sensor with the light of a flashlight. A flashlight scatters the light only in the area that the beam angle allows. The wider the angle of the flashlight, the more the light will capture.

The transmitter is like a flashlight and illuminates the water in a cone. As with the flashlight, the beam angle is also crucial for the sensor. Because the larger it is, the more the encoder detects it. There are different systems that are suitable for different areas of application.

How much does a good fish finder cost?

We compare fish finders from different manufacturers. The cheapest fish finder currently costs around 100 dollars. If you have more budget, you can grab the most expensive and high-quality product for around 300 to 1000 dollars. If the budget isn’t an issue for you, consider buying the feature-rich budget fish finder.

Conclusion

If you really know what type of product you want to buy, you can use the brand as the first clue to start the search. For example, if you want to buy a high-performance fish finder under 300 dollars that can be considered semi-professional, we recommend you to go directly to a well-known brand.
