Portable Fish Finder Buyer’s Guide

With a wide variety of options and features, it can be challenging to narrow down the best portable fish finder for you. With these few considerations in mind, the choice doesn’t have to be a difficult one.


When looking for a portable fish finder, durability is a huge consideration and should not be overlooked. Think about where you plan on using this new fish finder.

Most people will be storing them in tackle bags and walking along trails or resting them on rocks and gravel. With the wide variety of situations you will put it through, it better be tough.

Check the outer shell for thickness and construction. Portable units will be thrown as far out into the water if fishing from shore. For long-term use, check if the unit can stand up to the test.

Screens are another area to look at when getting an idea of its durability. Some portable fish finders come with built-in screens. When transporting, it is likely around hard objects like fishing baits and tools. You want a screen that won’t crack or scratch if it happens to come in contact with one of those items.

Getting a chance to hold the unit in hand is the best way to determine durability. If you don’t have that option or plan on buying online, the reviews are a great place to read about first-hand accounts of the product being used.


A portable fish finder would just be a fish finder if you couldn’t easily take it places. When you are thinking about portability and what will work best for you, take a look at your current setup. Are you using a tackle box or do you carry your fishing gear with a backpack?

Depending on your current situation and how you plan on carrying it will be the determining factor in the shape/size you want to get. Some anglers like to pack as efficiently as possible, while others bring everything they own.

The weight of the unit is an important attribute to look at. Battery design has a large impact on weight, and a lot of extra weight carried for extended periods can have an effect on how long you are able to fish.

Design is another component that plays a part in how portable a unit will be. Some portable fish finders come with display screens, while others utilize smartphone capabilities. Generally, the units without display screens are more portable because there is only a transducer housing.


Every brand has a different user interface or how the options and settings work together. Some are very basic, while others can be pretty technical. Portable fish finders come in all different varieties.

Basic user interfaces can include a single button that allows you to turn the portable fish finder on/off and filter through a list of preset screens. This is more of a turn-on-and-start fishing setup that would be preferred by a more novice marine technology user.

More advanced options allow the user to adjust screen and sonar settings, which can fine-tune exactly what you are looking at in the water. Not all fishing conditions will be the same, and having a unit that allows you to tweak settings will give you a more customized experience every time you hit the water.

Sonar Capabilities

Sonar technology is what allows you to see what is under the water. A sound beam is emitted and returned to the transducer. There are several different kinds of sonar available in portable fish finders, with the following being the most popular:

2D: The most standard version of sonar. Is primarily used for tracking how deep you are or if fish are directly under the transducer.

Down Imaging: This sonar frequency gives you an extra level of detail. With greater clarity, it will show details that allow you to see what you are looking at.

Most portable fish finders will come standard with 2D or a variation of it. Clarity of what you are looking at can be added with down imaging if the unit has that sonar option.

Depending on the screen type or size, it is possible to look at both sonars at the same time. Viewing multiple sonars at once is often accomplished with regular fish finders.

Display Types

There are two main categories of displays. One that comes with the portable fish finder or one that connects to a smartphone via wifi or Bluetooth. There are tradeoffs for both.

When the package comes with a display, there is no need to have a phone or deal with pairing issues. Depending on the environment you will be in, a solid transducer and display can work better.

On the flip side, pairing a transducer to a smartphone will give you better screen clarity and, ultimately, more options through the app interface. Nowadays, it seems like everyone has a phone with them at all times, so it’s not a huge burden to have the extra piece of technology.

The downside of using a phone is the ability to hold it. You most likely will need to get another piece of equipment. Propping it up can prove to be frustrating if it keeps falling down.

Regardless of preference, there are plenty of options when it comes to the display with portable fish finder units.
