Types of portable fish finders

When you consider a fish finder, you should think about the three main types of portable devices in the market that are portable, mountable, and castable units.

Portable finders

Portable finders are slightly larger than your hand but lightweight enough to carry with you on the go. The transducer is used to send readings to a screen, and there are some buttons you can press to perform with the settings. Some models have fancy color LEDs, while others have straightforward displays.

They are reliable, give accurate readings, and in most cases, have good battery life. They are easy to use when reading graphs on the screen. It can be used for open water fishing or ice fishing but performs best while used with small boats.

Castable finders

Castable finders are the high-end devices that use Bluetooth and Wi-Fi features to connect in smartphones. The transducer looks similar to a ball and fits in your palm. It will connect to your phone so you can analyze the readings. Most of the models also work with Android and iOS devices.

It comes in a compact size that easily fits in your pocket. If you are tied up for space in your fishing supply bag, this may be an option to consider. It is an ideal one for bank fishing, but also perfect for boat use.

Mountable finders

Mountable finders are standard units, and the display looks like a different portable fish finder. But the twist is that they can be mounted semi-permanently in a boat or kayak quickly.

It comes with a C-clamp that you can tighten or loosen to adjust the grip. This grip makes it perfect for kayak fishing, canoe fishing, and boat trips. They are also the only fish finder we know that can work with a float tube.

Things to be considered when buying a portable fish finder

Fish Finder is an electronic device that uses sonar technology to display underwater objects. It is an excellent device to detect all kinds of fishes from small to large ones. If you need to work, there is no need to mount it to the boat. Traditional fish scanners have to work hard on a boat. With these finders, you can fish from shore without worrying about logistics. They are quite lightweight and compact to fit in your pocket and connect to your phone.

If you want to buy the best portable fish finder, we are here to guide you to find the best portable fish finder to suit your needs. There are several facts to consider when buying a suitable fish finder.


When selecting the best fish finder, try to find the proper frequency range. This frequency range is an essential feature in the transducer, as it detects fish with frequency assistance. Generally, there are 3 types of frequencies in the market from 50, 83, 192 to 200 kHz. The High-frequency transducer creates vivid images on the screen.

Maximum scanning depth

Maximum scanning depth is also an essential thing, but it depends on your needs. If you want to use a fish detector in shallow or deep water, you need a maximum scanning depth detector. The maximum scanning depth on each device varies from 500 feet to 5000 feet per unit.

Superior transducer

The transducer is an integral part of a fish finder, which is responsible for tracking and detecting fish. This transducer sends and receives the sonar wave’s message, and when you send the waves to the water, and they hit the objects, the transducer selects those objects.

The transducers gave the entire data of underwater, and that data is translated into an image, which would be displayed on the LED screen. These transducers come in a variety of mounts and are plastic, so you can quickly assemble the transducers.

Wide cone angle

The cone angle determines the width of the beam, and an extension cone covers a wide area. The more extensive coverage allows you to look across the water, and finally, you can get a more precise picture. High-quality fish finders come with a fixed cone angle of 30 or 40 degrees. So choose a fish finder with a wide cone angle.

Types of sonar

The fish finder utilizes the kind of sonar that is very significant. Most fish finders use CHIRP (Compressed High-Intensity Radiated Pulse) sonar because it generates a potent sonar signal, which is used for detailed mapping. So choose a fish finder with CHIRP sonar technology.

Power rating

Power rating is a critical thing while choosing the best fish finders, and it determines the speed and efficiency of fish finders. All finders have a power rating that is measured in watts. Some units have low ratings, and some devices have a high power rating. Low wattage fish finders show slower performance and higher wattage fish finders offer faster and more accurate readings.

GPS navigation

Try to choose a fish finder that belongs to GPS navigation, and GPS can be used with satellites not only to locate a fish but also to identify the hot spot for future fishing. 

Each company uses a specific GPS network and determines the quality of the connection. The Garmin brand employs an excellent GPS network, and their fish finders have high reliability on GPS functionality.

Display quality and screen size

The display and screen help to read the measurements accurately and look at the images precisely. That is why; this is the most important thing among fish finders. So, find a fish finder with a great display and high resolution about 240×160 pixels. The High resolution allows you to see the most detailed image and transparent image.

Screen size is a significant feature in fish finders, so choose a screen size depending on the size of your boat. If you have a small kayak and canoe, the 3 “display is regular to adjust in small spaces. If you feel it is too hard to see the readings, then you can opt for a slightly larger screen.

Color options

There is no competition between the black, white, and color display. The color display is a better option than a white or black display, and it will allow you to see the measurements in cloudy weather. Also, the black and white screen does an excellent job.


A portable fish finder is plugged into disposable batteries, rechargeable batteries, and a 12-volt power source. Therefore, we recommend disposable batteries because you can recharge it with a separate cable. The battery life is also an imperative factor while selecting portable fish finders.

Waterproof rating and warranty

LED screens are damaged due to splashing water, so buy a fish finder with an IPX7 waterproof rating and choose a fish finder with at least a minimum one year warranty.


Price always plays a vital role in every fish finder. The cheap fish finder does not have all the features, and the expensive fish finder comes with all the specific and useful features. It would help if you bought the fish finder for $ 50 to $ 350 that suits your needs and money.

Final Verdict

Portable fish finders provide the fabulous convenience and ease of use that you can’t get from traditional finders. So if you have never tried a portable fish finder before, it might be time to add one to your toolbox.

A portable fish finder can entirely change the way you go fishing and what you experience. They not only expand your fishing range but also helps you to catch more fish. These are suitable for kayaks and coastal fishing, as well as open water angles, and portable fish finders are an excellent choice for casual anglers and small boats.

Now, you have read this guide about the best portable fish finders, and you can make an intelligent decision about which model meets perfectly for your fishing needs.
