Top 7 Best Portable Fish Finder Buying Guide

Before you invest in any product, it is very important that you do thorough research on the factors and features that distinguish between a high quality fish finder and a poor quality one.

Although different fish finders come equipped with different features, most of the high quality ones will come with at least one or two of the below mentioned factors.

It is also important that you keep track of your own budget when buying the best portable fish finder. This is because the features of different fish finders will actually make the price of the product variety as well. 

Therefore, if you want to know our take on it, do not go overboard with the splurge. First and foremost, note down why you really need a fish finder, and for what kind of fishing as well.

Before we get to all that, let us discuss the factors that you need to consider before investing in any kind of fish finder on the market.

Without further ado, let us get right into it.


First and foremost, the display of the fish finder is the most important part of it, since that is what you will be looking at for details. However, some manufacturers actually produce very expensive fish finders that come equipped with a very tiny display. Should you be getting that for your next fishing trip? We think not.

Without a large and high quality display on your fishfinder, working with the product is basically useless and a waste of money. There is no point in investing thousands of bucks (yes, you heard that right!) in a fish finder that comes with a small display of only 1.5 inches.

So what size should you be looking for here? Well, the portable fish finder will come equipped with a display size of at least 2.5 inches to 7 inches at most.

Although the latter size range is not completely necessary, you can still expect the top brands to equip their branded products with such specifications.

You do have to remember that budget is also a very big factor here. A good fish finder will come with a moderate display size of about 3.5 inches. You should invest in an equipment integrated with this kind of display since it will most likely be portable and lightweight. 

On the other hand, we also have the type of display that you need to take into account here. When dealing with portable fish finders on a budget, you will obviously want to invest in a product that will not empty your pockets in a day!

However, it is also important for you to invest in a quality fish finder that comes with a high-quality display. It will clearly show what you are supposed to be seeing for information regarding the situation under water.

In this case, a fish finder with an LCD or LED colored screen will be your best bet. Although falling on the slightly expensive end of the spectrum, you can expect such fish finders to portray a clear, crisp and bright image of the situation down below. 

Moreover, the LCD or LED display of a high quality fish finder will also be able to work well under the harsh rays and glares of the sun. It will also provide bright and crystal-clear images in high definition during the dead of the night.

But in any way, we do not want to force you here. If you are on a tight budget, you can surely go ahead with black and white display fish finders, as they are not all that bad either.

Of course, you cannot possibly compare the two display types here, but it will surely be worth the money as well. This is especially if you have to keep track of your total expenditure by the end of the day.

We suggest you not invest in an achromatic display fish finder because of the minimal information portrayed by it. The entire point of investing in a fish finder is to be able to distinguish between the vegetation, debris and fish down there, right? 

The problem with a monotone display fish finder is that it can be difficult to differentiate between all those variants. Therefore, you can never really know if you are casting a line for the right stuff.

On top of that, the glare resistance of a black-and-white display fish finder can be really poor. Do remember that we say this in comparison to that provided by a colored LED or LCD display.

Working with a grayscale display fish finder can be really hard. This is especially if you are working right under the harsh sunlight or around the break of dawn.

Water Resistance

Another important feature that sets apart the fish finder from a poor one is it’s water resistance ability. You will obviously have to make the product float or even dive into different kinds of water when fishing.

In such scenarios, working with a product that will not corrode too easily will help you out. On top of that, the anti-rust feature of the fish finder will also ensure that it lasts longer. 

When investing in the best portable fish finder, check if the product comes coated with an anti-rust substance or not. Most renowned manufacturers will make sure that their produced goods last you for a really long time. This is thanks to the water-resistance coating that the product comes equipped with.

The Budget of Best Castable Fish Finder

Of course, we just had to mention your own budget here. The thing about fish finders is that you can find this product in many different price ranges. The price range of the fish finder falls anywhere within 100-500 dollars. 

This is why it is important that you do not invest in just any kind of fish finder. You will want to invest in a product that is worth the extra splurge. Do make sure that it offers a range of features that you can use on a day-to-day basis.

Remember that your product should also have an array of features that will give competitors a run for their money. Your chosen fish finder should be lightweight, packed with amazing features and also budget-friendly at the same time.

In our list above, we managed to mention products that boast amazing features yet can be found at a budget-friendly price range.

Our fish finder picks are also very versatile. They come packed with amazing features that will assist you in your fishing trips on a daily basis.

Depth Reach

As a general rule of thumb, the main feature of a fish finder is its depth reach. Without a good maximum depth reach, you won’t be able to see what is lurking beneath the surface. As a result you will also miss out on potential catches.

In this case, you should invest in a high-quality portable fish finder that can easily scan up to at least 190 feet in total.

Today we included products that usually have a depth reach ranging from 150 to 330 feet in total. One of the products had a maximum depth reach of 600 feet as well, so you get the gist here.

The depth-reach that you want from the fish finder also depends on the kind of fishing that you’ll be doing.

Many fishermen, especially professionals, require a total depth reach of at least 350-600ft to scan a wide area. This kind of depth reach is mainly required for saltwater and rough water fishing.

If you are a beginner, you can easily go for a depth reach of 150 feet to 300 feet only.

You also have to determine the fish you want to catch, and therefore plan accordingly. If you want to capture small fish, you should go for a fish finder with a total depth reach of 330 feet or so. We say so because small fish are usually found near the sea bed. 

In the end, everything actually depends on you and your fishing preferences, so just make sure to shop accordingly.

Extra Features

If you want to get the fish finder, try to look for one that comes with the following extra features!

A durable carrying or travel kit

This kit is what will allow you to travel with the fish finder and its additional equipment. We have mentioned two different products in our article today that come equipped with a portable kit.

GPS Tracker

A GPS tracker is a very essential part of any high-quality fish finder. The GPS tracker will allow you to stay with the device in real time. It will allow you to follow where the product takes you as well.

It is important for a fish finder to come equipped with a GPS tracker that works in real time. Mainly because it will help you find the device in case it sinks or loses connection with you.

Frequently Asked Questions

Is a portable kit for a fish finder heavy?

No, a portable kit is actually not too heavy. However, it does add a bit to your own weight. But a portable kit is very helpful as it allows you to travel with the whole inventory at once.

Can I use a portable fish finder on my kayak?

Yes! You can easily use a portable fish finder on a kayak. Do make sure that the product comes with a durable mount. This is so that you can place the device on it to be completely hands-free at all times.
