What To Look In Best Portable Fish Finder | Ultimate Buying Guide

Pocket size and hand-held fish finders have been trending these days. If you intend to buy a portable fish finder, we have listed our top features and specifications. By reading this article, you can know how to choose the best portable fish finder.

GPS integrated 

GPS integration is a remarkable feature. You can do fishing safely using GPS connectivity. The users can accurately navigate the waterways with the help of the fish finder GPS Combo. Further, many fish finders come with pre-loaded or built-in maps of different states. Thus, you can easily plot the best fishing spots to have successful fishing adventures.  

Cone Angle

Cone angle helps you to observe in detail in the deep waters. The larger the cone the broader the water details a fish finder can locate. But you can work more accurately with the narrow-angle. However, it all depends upon the fishing situation, depth of water, etc. Cone angle shoots out from the transducer in deep water and detects the water details. 

Side scan vs. Down Scan

In shallow water, sided scan works great. The users can detect what is next to the boat. You can throw beams at different angles to get detailed information about the water objects. On the other hand, a down scan helps to navigate under the boat. The down scan is the best option if you want to fish in deep water. 

Mounting type

Decide whether you need a fixed fish finder or a portable one. In larger boats and ships, it is convenient to use fixed fish finders. On the other hand, smaller boats, kayaks, and canoes go on well with portable fish finders. Due to lesser safety on small boating structures, users keep the portable fish finder in hand while moving inside the boat. 

Hence, portable and handheld fish finders are ideal to use for all types of boating adventures. 

Vessel specific Fish finders

Vessel-specific fish finders’ features are compact and smart. What type of boat you use, depth of water, and fishing adventures contribute to the need for the different types of fish finders.


The transducer is the brain of the fish finder. If the transducer is of lower quality, the fish finder will irritate you. Without a transducer, a fish finder is a blank screen only. Transducers use sonar beams while catching images from underwater. It sends and receives signals to get accurate information about water objects. 

Some fish finders use single transducers while high-definition fish finders may use more than one transducer to enhance the navigation and detection feature.


The display should be visible in bright light and dim light both. Further, you need a standard screen size to see clearer. With too short a screen, you cannot view the water details. It is wiser to choose a medium-sized screen that does not impair your vision.


A common fish finder comes with 50kHz to 200kHz frequency. However. Fish finders have the features to detect lower frequencies up to 15kHz as well. Similarly. Frequencies above 200kHz are also found in rare fish finders. 

Some Additional Features To look for in a portable fish finder?

Quality of the transducer

A transducer is the heart and brain of the fish finder. If there is no transducer in the fish finder, it is a stale device. A transducer is a tool that sends and receives signals to and from water. Transducers use advanced sonar technology to detect and create imaging on the fish finder screen. So, make sure that the desired fish finder consists of a high-quality transducer. 

Power rating

Power rating shows the ability of the sonar technology. How powerful the sonar beams are to catch up with the imaging? The more powerful the sonar technology, the more efficient the signal-picking capability. 

The power of the Sonar is measured in RMS and peak to peak. Usually, regular fish finders are available with the power of 500 watts RMS to 800watts RMS. However, in larger fish finders, the power of 100 watts to 3000 watts RMS is available.  


A fish finder operates with batteries. Batteries are available at 12-24 volts. In exceptional cases, larger batteries are also available. A smaller fish finder consumes a 1-3 amp battery per hour. However, larger devices can utilize up to 7amp per hour. So, check out your usability before buying the device. 

Portability and ease of transportation

The smarter design of the fish finder makes it more portable.  Handheld and detachable fish finders are popular for convenience and luxury features. It is quite easy to carry portable fish locators anywhere. Potable fish locators are available in sizes as lower as pocket size. However, some portable fish finders can be packed into handbags. 

Display quality

Several features contribute to display quality:

  • Screen size: Screen size should be enough to view all water objects. 
  • Screen resolution: Fish finders are available in High Definition image quality as well.  
  • Display in daylight: While rowing a  boat you have to do fishing in dim light or bright daylight. Make sure that the fish finder you.  are selecting is competent enough to work in all types of light

Screen size

The available screen size range is between 4 inches to 12 inches. A 4-inch fish finder is a smaller size and water targets may not be visible clearly. On the other hand, the 12-inch screen size is larger enough to view all water objects accurately. 7-inch screen size is standard. You can view all navigations and directions efficiently. 


Before buying, you need t check out all types of connectivity in the device. Bluetooth connectivity helps you sync phone data with the fish finder. It can help you navigate maps and locations directly from your handset. 

Furthermore, check out the option of GPS connectivity. Make sure that GPS is capable enough to navigate different locations and objects in the targeted area. 

Cone Angle Frequency

The cone angle is another important feature. The wider angle shows wider visibility of the underwater world. However, a thin angle gives an accurate image of the objects. 

The efficiency of the cone angle depends upon the quality of the transducer. So, check out the transducer and its working mechanism. 


Nearly, all fish finders are waterproof. Each fish finder has a certain capacity to sink in the water for a fixed period. Water resistance technology makes the device durable and long-lasting. 


The cost of portable fish finders varies from brand to brand. The higher technology a fish finder has the higher the cost of the device. GPS connectivity, transducer quality, sonar technology, and quality of imaging contribute to an increase in the cost of the fish locators. the cost of the fish finders ranges from $100 to $600 or above as well. Commercial fish finders are of high cost. 


With this, our research comes to an end and we conclude that the best on the list is “Garmin Striker 4”. One has to admit the advanced technologies make it work professionally. It gives three different types of displays of underwater creatures. It is lighter in weight and has a robotic interface with string GPS that allows you to make your maps yourself and mark their favorites. We are highly impressed by the functions it offers.
