Types of Portable Fish Finders

As you must have realized that the choices for portable fish finders are endless. If you ask “What is the best portable fish finder?” The answer will depend on your fishing preferences and the type of boat you will be using. Broadly there are three types of portable fish finders to choose from:


Portable/Handheld Units

These portable fish locators are one of the most common models that you can find in the market. They feature a decent-sized screen, generally larger than your palm, which allows you to read the sonar feedback comfortably. While some come with high-resolution LED displays, others follow a simplistic approach. Nonetheless, these models are quite reliable, accurate, and also offer a good battery life. They are also easy to use as you can access different functions through the buttons. The only drawback is that they are not very compact. In case you are using a canoe or a small boat, using them can be a problem. The best handheld fish finder options would be Humminbird 5, Garmin Striker 4, or LUCKY Portable Kayak fish finder.


Castable Units

The castable fish finders have a futuristic approach and are more convenient to carry along. These portable fish locators can connect with your smartphones via Bluetooth or Wi-Fi and relay all the sonar feedback through a free app. Most of these fish finders are compatible with iOS and Android devices. The biggest advantage with these top portable fish finders is that can easily fit in your pocket if you are short of space. Since they use more advanced technology, they might not be compatible with older phones. The wireless connection also tends to break at times leading to discrepancies in sonar data. Some portable fish finder reviews also complain about their battery backup which can be a big downside when you are out and about in the waters. The top rated portable fish finders in this category are Deeper PRO+ and ReelSonar iBobber.


Mountable Units

The third type is the less common semi-mountable portable fish locators. These fish finders come with a C-clamp mount that you can fix on our canoe or kayak through its adjustable grip. The perfect example is the Humminbird Fishin’ Buddy MAX.


What is the Best Portable Fish Finder? – Buying Guide

Though you have the best options for top rated portable fish finders in front of you, we know that the dilemma doesn’t end here, Right? Therefore, to choose the right model for your fishing need, you must keep the following factors in mind:


Display Quality and Screen Size

You need a screen with good clarity to be able to read and analyze the data. You can go with a high-definition color screen or opt for a traditional black and white display. You must also select a screen that offers better readability in direct sunlight and if you plan to go for night fishing, the backlight feature is a must. When it comes to the screen size, you must consider your boat size and your comfort. Most of the screens come in a range of 3.5 to 5 inches. Some of the best handheld fish finders even come with a smaller display.


Quality of the Transducer

The efficiency of your fish finder ultimately depends on the quality of the transducer. Since the companies don’t really advertise the transducers, you can go through the popular portable fish finder reviews to gauge the accuracy of the reading of the model you are planning to buy.



You must select a model that is compact and easy to carry along. The size of the fish finder matters, even more, when you are fishing on a small boat or kayak. So, even if the fish finder offers a lot of features but is too big to handle, it can become more of a hassle than help.



It is better to opt for a Dual Beam sonar that lets you adjust the frequency emitted by the transducer. This feature especially comes in handy when you plan to fish both in deep and shallow waters. Higher frequencies will work better in shallow areas and lower frequencies are best for greater depths.


Powering Capability

Fish finders are powered in three ways – rechargeable built-in batteries, disposable batteries, or plugged into a 12-volt power source. While the powered ones are cheaper, they are less portable. Since portability is your main criteria, we would recommend going for battery-powered models.



It is an irony that not every fish finder is waterproof. While their transducers are waterproof, the display unit relaying the data is not. You don’t want your device to conk off after a few encounters with water splashes, which is certainly a part of the fishing sport. Hence, it is always better to invest in a waterproof unit.



It is always a wise idea to have a budget in mind so that you are not carried away with the swanky features offered by the top rated portable fish finders. The cheaper units also do the job fairly well, though they may lack some functionalities such as GPS and networking. However, if portability is not one of the key aspects you’re looking for in a fish finder, here are some budget friendly fish finders under 200.


How to Use a Portable Fish Finder?

If you are a beginner, operating a high-end model can seem a bit daunting. However, portable fish locators function more or less the same way. Here are the basic steps to set it up and running:


  1. Switch on the scanner and if it is an app-based unit, connect it with your smartphone through Bluetooth or Wi-Fi.
  2. Use the physical buttons on the device or use the fish finder app to make adjustments in the settings as per your requirement.
  3. If it is a castable unit, attach the transducer to the fishing line and cast it out in the water. Else use the float to drop the transducer near the boat. You can also attach it to the hull of your boat using the suction cup mount.
  4. Wait for some time for the sonar to start sending you feedback. While some models will display fish arches others will show you a fish icon. All you need to do now is follow the location and catch the fish.


Situations to Use a Portable Fish Finder

As the name suggests, portable fish finders can be used practically in any fishing situation. The only thing that can throw off the readings are the water currents and suspended particles. Mentioned below are some of the common situations that call for the use of a portable fish finder.

  • When you do not own a boat
  • Ice fishing
  • Kayak Fishing
  • Shore fishing
  • Fishing from a dock or pier
  • Night fishing
  • When you have no place to fix the fish finder on your boat


Frequently Asked Questions

Q: Are all portable fish finders waterproof?

A: While they should be waterproof since you will be using a fish finder out in the water, unfortunately, they are not. Even though the transducers are waterproof, the display screens are not and can get damaged with a splash of water. However, the high-end models do come with an IPX waterproof rating.


Q: Are portable fish finders better than mounted fish finders?

A: Mountable fish finders are more permanent fixtures that require the transducer to be installed under the boat and wired to the motor. The display unit also needs to be mounted permanently on the boat. These types of fish finders work well if you own a boat. If you don’t own a boat or want to rent one, or even want to fish from the shore, portable fish finders are a better option. They give you the flexibility to fish from a kayak or a canoe. They are easier to set up and are less expensive than the mountable units. Their transducers are also flexible, you can cast them out, throw them in the ice hole, or attach them to your watercraft.


Q: I am looking for the best portable fish finder ice fishing, which one should I buy?

A: In our opinion, the Garmin STRIKER 4 is the best handheld fish finder that is suitable for ice fishing. The built-in flasher mode can be used from a stationary position to display real-time sonar feedback on a circular scale. You can have both 2D sonar and flasher in a single device.


Q: What is the best portable fish finder for shore fishing?

A: The Deeper PRO+ is an excellent choice for shore fishing. This device offers a good range and comes with a built-in GPS system that allows you to create detailed bathymetric maps from the shore, bank, or dock.


Q: Which is the ideal location for mounting the fish finder on my vessel?

A: There is no definite answer as it comes down to the type of boat and your installation requirement. Ideally, the location of the transducer should be as close to the centerline of the boat, on the transom in smaller boats. The transducer also needs to be in contact with water all the time and sit as close to the level as possible. Many anglers also prefer mounting their transducers on the hull mount or through the hull mount. The signals and echoes received this way are quite clear. However, turbulence or air beneath the boat might interfere with the signals. Then, few prefer side mounting where the transducer is placed on a lengthy pole affixed to the side of the boat. It helps to reduce noise and avoid the risk of making a hole in your hull.


Q: Are all the best portable fish finder GPS enabled? Is GPS necessary?

A: Not all portable fish locators come with a built-in GPS. Whether you need a GPS or not depends on your fishing habits. If you prefer fishing from the shore, GPS is not necessary. When fishing from a boat or kayak, a GPS-enabled device can help you mark hotspots and you can make custom maps. If you do not wish to invest in a pricy fish finder, you can let go of the GPS functionality.



Portable fish finders can be a more convenient option for anglers for several reasons. When it comes down to the best handheld fish finders, there is plenty of fish in the sea, pun intended! You have the choice between single or dual beam, colored or B/W display, castable or mountable units, and much more. If you are new to the world of fishing, start off with a portable unit as it is more budget-friendly and easy-to-use. With that thought, we hope that our portable fish finder reviews for the top picks will make your decision easier. So buy one for yourself today and start exploring the waters.
