Buyer’s Guide

As you have already learned from our reviews, the fish finders have great differences. Therefore, you have to purchase a device that is adapted to the use as well as your ideas and your skills. This results in various criteria that you must take into account when making a purchase.

The depth

For each model of fish finder, the manufacturers state to what depth it will work and how much good data it will present. For example, if you are fishing particularly in shallow water, you don’t need a professional device that works to 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 acquire 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 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.

Devices above the value are much more accurate because they send out more waves in a very short time and you also get more data. The type of fish finder and the associated broadcast cones also 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, you should opt for a system with dual-beam. 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, 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. However, it should be clear to you that the more powerful the devices are, the more expensive they are.

Underperforming fish finders sometimes have great 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 essential, 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 your 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 good picture.

Fish Finder Function

Apart from that, there are 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 also be advantageous on the water in sunny weather.

The functions

Not every fish finder has the same functions, so you should take a good look at the different models and also find out about the possibilities. For example, the system side imaging is integrated with some devices, which also enables you to have a side view of the underwater world. In this way, you will also 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 are also equipped with a GPS. So you can save a spot with lots of fish and quickly find it the next time you go fishing. The device also stores distances traveled and enables 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 due to 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 can also 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 is also reflected in the price.

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 ejectable 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. 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 also an important purchase criterion. Most models use a small battery as a power supply. The same applies to the data display device, although a battery is rarely installed. In this regard, 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. An alternative is offered by stationary models, which you have to connect to the boat engine.

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 afterwards.

The dimensions

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

Many encoders are already very small, but the display device needs the right size. It should not be too large for good handling, on the other hand, it should 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 particularly 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 also easily attach some display devices to the boat or fishing rod.

The weight

In addition to the size, the weight is also decisive, which should be as low as possible. A light fish finder is particularly advantageous 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 a long shelf life. If you notice cracks, bad transitions or cavities when you buy the fish finder, it will not serve its purpose for long. Because electronics are also installed here, which can break due to the influence of water.

Even the data display device can accidentally come into contact with water so that the component should also 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. In addition, well-developed test results are a sign that it is a promising model.

If the manufacturer is convinced of his fish finder, you will receive a guarantee for a few years. Under no circumstances should you waive the warranty claim or the right of return within a few days. Especially from the fish finder, you can buy a model that is too complicated for you or does not show the desired information.

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. Familiarize yourself with the device and study all important information on the promising application. Only with a good understanding you can use the fish finder properly and really benefit from it. Despite the differences, some basic functions are the same.

Some fish finders 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 also 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 also always includes the necessary batteries or the rechargeable battery and instructions. In the case of 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, as you will receive a fish finder in a set with all the important parts.

Is there an alternative fish finder or sounder?

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 also 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 also 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 500 dollars.

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 that can be considered semi-professional, we recommend that you go directly to a well-known brand.

Now you know all the information about how to choose the best fish finder. Pick the one model that will meet your expectation. If you have any questions you can ask in the comment section below.
