How To Choose The Best Portable Fish Finder – Buying Guide
As you can see, there are many different high quality portable fish finding units available on the market today. Before you begin your search for the best unit for you, we recommend gaining a thorough understanding of the different features to look for. Like all electronics, there is sophisticated technology that goes into making these units and therefore it is wise to know what features to look for. To help, we have listed the top features and specs that you should be familiar with before choosing your ideal model.
Portable Vs Castable Units
Castable fish finders work much like the name suggests. By securing it to your fishing line you cast the fish finder in the water and let it float on top the water like a regular bobber. Once coming into contact with water they begin to work. These are ideal because you can cast your line farther out into the water for an accurate reading of what is directly under your line.
We tend to break fish finders up into three different categories, or types. First, you will find GPS portable fish finders. These tend to be the units that are the most advanced and are ideal especially for those who prefer to fish in the ocean. As the name suggests, these units will not only tell you what is going on below the water with the help of a sonar but will also help you to get back to shore safely with the GPS reading. These units are ideal as they will pinpoint your location in order to remember locations that are prime for fishing.
Next, we have standalone fish finders that feature sonar similar to the first type but do not have GPS. This is a popular type as it comes in at a cheaper price while still delivering exceptional performance. With some units, you can even add on GPS later if you find it will be useful. Lastly, there are some fish finders built for our modern world of connectivity. These units are perhaps the most expensive option but allow you to use hotspots to share pictures online.
This part of your fish finder is important as this is the part that detects what is going on below you. It does this by sending sound waves below the water. The quality of your transducer has everything to do with the cone angle. When looking for your next finder, you will want to look at the beam width. The wider this is, the more you will be able to see. These will vary between 9° and 60°
The power rating will be measured in watts. The more wattage your unit has, the faster the readings will be displayed on your unit. Not only that but a higher wattage will allow your unit to go deeper while still recording accurately. We generally recommend you opt for the most powerful unit you can afford, especially if you plan to fish in deeper water or frequent saltwater. If you are planning to fish in shallower waters, the power rating becomes less important.
Screen Size And Resolution
As you may know with your phone or television, your resolution is recorded in pixels. Pixels are singular small dots on a screen that works to make the picture you see. When all these pixels, or dots, are put together you get the resolution of your screen. As you may guess having a screen with only 5 pixels will look a lot less crisp than a screen with 50. The higher the number of pixels your screen has, the more detail you will be left with. We recommend going with a screen no less than 160 horizontal pixels by 240 vertical. This is the bare minimum you will want to go keeping in mind that a higher resolution will be much better.
As you may guess, the number of pixels needed will directly be affected by the size of your screen. While you may want to keep your screen small on your unit as to keep it more portable, make sure it is still easily readable. Finding a nice blend of screen size and resolution quality is important.
When fish radars first came out, their screens were black and white in color and quite pixelated making it hard to see, especially in situations with glare. Luckily as technology has progressed most fish finders come with fully colored screens. The added technology has led to more detailed pictures that are easier to read. This allows you to use this sonar in bright sunlight and torrential downpours while still being able to clearly read your screen.
Ease Of Detachment
Some portable fish finders are able to be attached to your boat, kayak, or even fishing line. Having one that is easy to attach and remove will allow you to be able to get in and out of the water quickly.
For fish finders that attach to a boat, you’ll want to look for packages that have lots of transducer line. This will make setup a breeze. Also, depending on the type of boat you may want to permanently secure the fish finder. Usually, there is a sensor that is attached to the boat which the screen is then secured to. This will give you a system that is not only easy to setup but can be detached with minimal effort. If you are wanting an even easier time you can simply detach the screen unit and leave the other wires setup for next time.
If you have a fish finder that is designed for casting you’ll want to ensure it is easy to detach and adjust while on your line. Most castable fish finders have an easy way of attaching it to your fishing setup. These are in the shape and act like, fishing bobbers so being able to raise or lower the amount of line according to the amount of fish at certain depths.
Wireless Or Wired Connectivity
Traditional units require you to wire your fish finder into an electrical system in order to operate. These units are typically a less expensive choice. While they do have a cheaper price tag, they can be quite limiting in that they need to be plugged into a boat in order to be powered. On the other hand, wireless units do not need to be plugged in. Instead, they are much more convenient when fishing from your kayak or from the shore. Wireless fish finders come with either WiFi or Bluetooth compatibility making them easy to upload your results.
As with all portable items, you will want your handheld fish finder to carry as light a weight as possible. Being compact, these units do tend to carry very lightweight constructions which makes it easy for you to bring it with you just about everywhere. You can expect lightweight options to weigh around 1 pound or less. These are an excellent option for people looking to fish from their kayak. For people with larger boats, the weight of a unit won’t be as important as they can have a dedicated mounting place for the unit.
If you are at all familiar with fish detectors, you have heard of a part of it called the transducer. This is the part of the fish finder that transmits cone shaped sound waves below the water to be able to pick up a full image of what is going on below the water. As you can imagine, that makes the cone angle quite important to the success of the fish finder.
The width of the beam determines how big of a view you get under the water. A wider degree of the cone angle the more you will be able to see under the water. Dual frequency transducers most often come with both a 20° and 60° cone angle. Most often, going with a cone angle of 20° is most ideal for fishing in a variety of depths.
A higher frequency will provide more detail on your fish finder screen. This is due to the fact that more sonar waves are being sent below the water and received from the transducer. The level of frequency that you use depends on the depth of water you plan to fish in. If you are fishing in shallower waters we recommend opting for a high frequency transducer, between 192 and 200 kHz is ideal. For deep water fishing, you will want a lower transducer of around 50 kHz.
Generally speaking, water and technology don’t mix well. For this reason, it is incredibly important to opt for a fish finder that is ideally waterproof but at the least water resistant. While you may be able to avoid your device being completely submerged below the water, you are quite likely to have splashes and rain come into contact with it. Fish finders typically require a fair sized investment. Ensuring that you have a unit that is built to withstand the wet conditions will allow your unit to last for longer.
Q: What Is A Portable Fish Finder?
A portable fish finder is a unit that incorporates sonar to be able to detect what is happening below the water. This unit shoots sound waves below the water in order to receive information of where the fish are below the water’s surface and send the information to the display screen. Unlike traditional fish finders, these units do not need to be hardwired into your boat and instead incorporate either disposable or rechargeable batteries in order to be powered nearly everywhere. They hold a lightweight and compact design that is able to fit into pockets or small areas and can be used for a variety of different fishing conditions.
Q: Is It Better To Get A Portable Or Castable Fish Finder?
For the time being, portable fish finders remain the more popular choice but castable fish finders are steadily growing in popularity. The choice of which one is better will mostly come down to personal preference. If you prefer to be able to cast your fish finder into the water or have it trail behind you as you paddle a lake, then the castable fish finder may be best. If you prefer instead to keep your unit close by, a portable option may be better.
Q: How Do Fish Finders Work?
A portable fish finder works much like the traditional fish finder but with the great advantage of not needing to be hardwired into your boat. These units work using sound waves. Transmitting these waves in a cone like fashion below the water they are able to track the fish below the water. They then send this information back up to your screen or smartphone in order to plot what is going on in the water below you. This information is then used to determine what area is a good spot to set up for fishing.
Q: Who Benefits Most From Portable Fish Finders?
Portable fish finders are incredibly versatile as you can bring them with you just about everywhere. All fisherman can enjoy the benefits of these units but those who tend to fish from non motorized boats such as stand up paddle board fishing tend to benefit the most from these units. These units are also ideal for those who tend to fish from the shore or docks as it will tell you the best places to set up without the use of an electrical source. Lastly, outdoorsman who tend to trek into campsites or fish from a variety of different areas and are looking for something as mobile as they are.

Q: How Are Portable Fish Finder Powered?
While most traditional fish finders directly plug into a power source, portable fish finders work a bit differently. To help them be both compact and easy to move, these units instead incorporate either internal rechargeable battery packs or use disposable batteries. There are pros and cons to both power sources. While rechargeable packs are better for the environment and are cheaper in the long run, disposable batteries are ideal because simply popping in new batteries will allow you to keep fishing for longer.
