The Buying Guide

In your search for the best portable fish finder, there are several factors that you need to pay attention to. This would help you narrow down your search, and in the end, you would have saved yourself a lot of time.

Let’s have a look at some of these elements.


Well, as the name should have told you by now, a portable fish finder should be portable. In this case, you should look out for factors that affect the portability of the device, and they include its size, the carrying case, and the transducer.

The Display

This is one of the most vital aspects to look out for, and the screen elements that you should focus on include the resolution and the color options.

Higher resolution means that you would have an easier time viewing the information on the screen. It is mentioned in terms of pixels, with the ideal resolution being around 240 x 160 pixels.

Additionally, colored screens offer more clarity than black and white displays, although the latter would still do the job in case the former is out of your price range.


The power requirements of your fish finder are also something that you ought to consider. An ideal fish finder is one with minimal mobility issues, and therefore one with a rechargeable battery should do the job.

Not all of them are powered by internal batteries, as there are some that need to be wired to the vessel’s voltage system.

Sonar Technology

This is what determines how easily your device would detect the fish in the water. If you want better results, we suggest that you go for a dual-band sonar system since this has the ability to detect fish at different depths and distances.


A flexible device would be more efficient since you can easily move it from one position to another without having to make significant changes to your vessel.

A detachable fish finder allows you to focus on the fish catching option rather than being occupied with the setup of the device.

The Transducer

This is what sends out the sonar waves, which should bounce off any object that they come across in the water. This data is sent back to a central unit, which transforms it into a visual interpretation of whatever is going on underneath the water surface.

They should be easy to install and uninstall plus are compatible with most of the boat types available.

Your Budget

Before you head out into the market looking for the ideal fish finder, you should have a price range in mind where your best pick would lie.

This is why it is crucial to do extensive research on the features you are looking for to ensure you make minimal compromises no matter the price.

Also, check out the warranty service and period as these are likely indicators of the quality and durability of the product.

How Portable Fish Finders Work

We thought it wise to give you a brief idea of how fish finders operate. Well, as you shall see, it is not as complicated as it may seem.

First, the device emits sound waves from its transducer, and they travel through the water until they bounce off something. When they hit something, they send a message to the device’s receiver.

The message that is sent back is analyzed and processed by a small computer, which determines how far the object is from the receiver.

It becomes easier to know how far your supposed target is, whether at the bottom of the lake or in the channel. All this information is displayed on the screen, and you can easily see what is going on underneath the surface.

Note that the fish finders operate differently. While some send their signals in a single direction, others send in multiple directions.

Types of Portable Fish Finders

As you search for the ideal portable fish finder, you should know that you have three main options to choose from. Let’s check them out.

Portable Fish Finder

This is the most popular choice, and it features a single unit held together by a nylon case. The key elements of such a unit include a screen, a transducer, and a mounting base.

It is well-suited for ice, and open water fishing plus is also ideal for use with a small boat.

Mountable fish finder

This would be a suitable choice if you need a permanent fixture on your fishing vessel. This is particularly so if you intend to go fishing in deeper areas that are only accessible via a kayak or canoe.

The only bit that you need to watch out for is the setup accessory whereby if you get the wrong tool for the job, you would never set up the device for use.


This is an advanced type that features a floating transducer that communicates with your smartphone via an app that you can download.

You should find it useful if you are fishing closer to the shore or along the river bank.
