How to Choose the Right Portable Fish Finder

If you’re looking for a best portable fish finder, there are some things to consider before making a purchase.


Fish finders come in various frequencies, such as dual, single, and multiple. The dual frequencies are ideal for looking for fish in shallow or deep water. The higher the frequency, the more details you’ll get.

This is important if you’re looking through a lot of debris, and are trying to determine what is a fish and what isn’t. You should figure out where you plan on using the fish locator, and determine the right frequency for you. You can use the multiple frequencies to use in different locations to assist you in finding the biggest catch.


The power of the fish finder is crucial to finding the right one for you. Fish finders are measured in watts, and the more wattage, the faster the information you’ll get. With more power, a fish locator can read deeper waters than those without the added power.

The amount of power is crucial to the depths you’re fishing, and lower power fish finders are ideal for fishing in shallow waters. If you’re planning on fishing on the open water, you want something with more power. It depends on where you plan on going fishing.

Screen Resolution

The screen resolution is important to understanding what you’re looking at on the screen. The greater the number of pixels your screen is, the more detail you can see. You should get a finder that has a minimum of 240 x 160 pixels, though the image may be blocky.

When you combine the resolution with the screen size, the better chance, you will have at finding the fish under the water. Just remember that the better the screen resolution, the better chance you have of finding fish through the unit.


Fish finders use either a color or a black and white screen. While they both provide the information you need, they both work differently. A colored screen allows you to see more things in bright sunlight, whereas a black and white screen is easy to see.

While black and white screens have started to disappear from most finders, you can still find one. Neither one is necessarily better than the other, and it does come down to personal preference. You may prefer the black and white style to the colored one, but they should work just fine on your screen.


The transducer is the most crucial part of a fish finder because it is what sends out and receives the sonar waves. When the sonar readings hit an object in the water, the waves are sent back to the transducer. This allows you to determine whether you’re locking onto a fish or some other object in the water.

Most transducers allow you to hook them up to the outside of the boat, which makes it easy to skim across the water. They don’t require too much technical knowledge to hook them up to your boat.

Advantages of the Portable Fish Finder

Here are some advantages to a portable fishfinder.


Compact fish finders are cheaper than fixed fish finders. It’s ideal for those on a budget, and need a fish finder that works just as well as a fixed finder. You’ll smile when you have more money in your pocket.


You can transport a compact fish finder easily and quickly. Since they’re not locked down to a boat or kayak, you can take them just about anywhere. It’s ideal for those wanting to try out new fishing holes, and expand their horizons.

They’re Easy to Use

A fish finder has everything you need to be successful. You don’t need to be a tech whiz when you’re using a portable fishfinder. You don’t need to spend hours setting it up for every location you go to. You can turn it on, adjust a few settings and drop your line out.

Use with Different Transducers

You can use a fish finder in just about any location. No matter if you’re fishing from a boat, dock, or the shore, the transducer allows you to fish in any spot. If you want to mount the transducer temporarily, it only takes a matter of a few minutes to hook up and start fishing.

What is a Good Price for a Portable Fish Finder?

f you’re thinking about getting a fish finder, you may wonder how much it will set you back to get a good one. Even if you’re not thinking about spending thousands of dollars on a fish locator, you should set aside a good budget for a fish finder. You don’t want to get a cheap piece of equipment, so you should expect to spend a decent amount of money on a fish finder.

If you’re looking for a decent price range, you may want to consider something between $200-300. This ensures you have all the features you’ll need to have a successful fishing trip without breaking the bank. While it may seem to be a lot of money for a finder, you should remember what you need it to do. You won’t need to spend too much money, but you should set some aside to get the best one for you.

Final Verdict - What is the best portable fish finder?
