Criteria We Used to Select These Products


We had to use certain criteria to make a list of the top five fish finders for this year. Although we paid attention to a lot of different things; we will include only the most important ones in the list below. 

The display

Having a good and readable display is one of the crucial elements. Without a good screen, you aren’t able to distinguish vegetation from fish or terrain. No matter how good your sonar is, it’s worth nothing if you’re unable to read the data on your screen.

The sonar

The sonar has to be a quality one; there’s no question about that. The reason is pretty simple. If you don’t have a quality sonar with various capabilities, the readings are going to be faulty. As you know, you can’t do a thing if you’re presented with wrong data, especially in a dynamic sport like fishing.

The price

All of these five products come with an affordable price. Some more expensive ones might have better things to offer, but it doesn’t mean they’re better quality in comparison to the lower priced ones. However, these five are complete, useful, versatile, and affordable. Those elements play an important role if you consider purchasing a good fish finder.

Advantages of Portable Fish Finders


People often don’t know the advantages of portable fish finders compared to the fixed ones. There are many of them, and we’ll list a few crucial ones.


First of all, the portable fish finders are cheaper than the fixed ones. Regardless if you’re a professional or a beginner, cost efficiency should always be on your mind. If you’re on a tight budget, opting for portable units is the way to go.


Portable finders can be transported and used in various locations. However, that’s not the situation with the fixed ones. Whether you’re fishing from a boat, shore, or a kayak, you can always bring your portable unit with you.

Ease of Use

These devices are very easy to use, and you don’t need any previous experience. However, there are many technical obstacles with fixed fish finders such as installation and calibration. As long as you thoroughly read the user manual, you shouldn’t have any issues with portable units.

The Flexibility of the Transducer

You can use the portable transducer on many different occasions. You can mount it on your boat, or throw it into the water; it’s up to you. This transducer versatility is what separates the portable finders from the fixed ones.

Things to Consider When Choosing the Best Portable Fish Finder


There are many things you should consider before buying a fish finder. The more aspects you manage to cover, the more success you’ll have. However, we’ve managed to exclude some of the most important things you should consider before choosing a product for yourself. Take a look at our list, and you’ll find some pretty useful advice.

The Frequencies

A good sonar is one of the most important parts of a quality device. The device is worthless without a quality sonar. Before choosing a unit for yourself, make sure to check out the available frequencies of that particular device. The frequencies are mainly separated into three categories – dual, single, and multiple. Many dual frequency transducers come with 50, 83, 192, or 200 kHz.

Higher frequencies are better for shallow waters, whereas lower frequencies work well in deeper waters. Bear in mind, the higher the frequency is, the more details will show up on your screen. Some of the top-quality transducers have up to 400 kHz.

The power

The power is also an important factor. The power of these units is measured in Watts (W). The greater the wattage, the better the readings are. Also, the overall power of the unit affects the speed of the readings. For example, with lesser wattage, you'll get the reading data much slower. That’s because your device translates the frequency waves it receives from the transducer. If the overall power is poor, the waves are slower, and the reading is blurred and out of focus.

However, the output also depends on the depth. In simpler words, if you’re in shallow waters, you’ll need less power. At 50 kHz your finder will show readings up to 400 feet, for every 100 Watts of power. At 200 kHz, it will show readings up to 100 feet, for every 100 Watts of power.

Screen resolution

When it comes down to the screen, everything is in the details. To be able to distinguish certain things on your display, you’ll need a good resolution. The principle is simple – the more pixels you have, the better the quality is. A bare minimum is a screen of 240 x 160-pixels. Everything below that is considered bad. In fact, even with this minimal resolution, the details are going to be pretty poor.

It’s worth investing in a high-resolution screen because you’ll get much better and sharper images. The resolution combined with the size of the screen is going to be the ultimate factor for how detailed your screen is. Revise your budget and don’t hesitate to invest in a higher resolution screen.

Black and White vs. Color

The color screens are almost mandatory nowadays when fish finders are in question. Although there are some black and white still available on the market, it’s a pretty easy decision. The benefits of color displays are obvious. Aside from the benefit of seeing in colors, you also get a much better insight into the details below the deck. Also, color screens are much easier to see on a sunny day, or in bright light.

Our Verdict:
Which Portable Fish Finder Should You Choose?


After careful analysis, we have come to the conclusion that Garmin 010-01550-00 Striker is the best product that you can get in this price range. It offers a lot of useful features and options. It’s also very easy to use and install without any prior experience. However, the most important element of this product is its affordable price.

The best thing about the Garmin 010-01550-00 Striker is the integrated GPS. You won’t stumble upon many GPS-ready devices for a low price. The benefits of having the GPS are great. First of all, you’ll always be aware of your position. Determining the exact position is pretty hard without a GPS, especially when you’re fishing on a vast lake. However, you’ll even be able to mark waypoints and come back by using the GPS.

Another amazing thing about this unit is the CHIRP sonar technology. While the vast majority of sonars use a single beam of frequency to acquire data, this one uses multiple beams thus providing a much better representation of the situation underneath the vessel.

The Garmin Company is well-known for their quality of production and durability of their products. So, as far as quality goes, this one is among the best-made fish finders on the market in its price range.
