A Little Background
A portable fish finder isn’t a cheat device – it’s a great way to save a lot of time when fishing in a vast body of water, such as a large lake or sea. It is also an important device if you are specifically looking for a certain species of fish.
It is important to have a fish finder that is bundled with a GPS so you can save more time in going to your preferred direction. GPS combo units also help the angler to save specific locations and favorite fishing spots wherever they go. GPS units also prevent the angler from getting lost at sea.
Most people believe that it is more ideal to get a low frequency sonar fish finder than a scanner if you want to go fishing out in the sea due to depth. This is because an image scanner fish finder is more prone to loss of signal so it is only ideal for lake fishing or any shallow water.
How We Picked
On choosing the best portable fish finder, below were our considerations:
Portability: the portable fish finder must have a small size that is easy enough to store into the angler’s pocket or be easily setup and removed whenever needed. The size of the portable fish finder is also important so that it will fit on most smaller boats such as kayaks and canoes, if possible.
Transducer size: the size of the transducer determines whether the portable fish finder is a great find or not. The transducer tells whether the portable fish finder is effective and sensitive enough to cover a larger area of water to catch and detect more fish and other items at the bottom of the water.
Power source: usually, any portable fish finder will run off a 12-volt battery source from your marine battery but some can also be battery powered, depending on the type of unit that you have.
Setup and features: the portable fish finder should be simple to setup and put together. At the very least, the portable fish finder should also include the mounting tool such as the transom mount with the transducer. The portable fish finder should also have instructions on how to mount it to your boat.
Durability: the portable fish finder should have long lasting durability and should have a good waterproofing rating for you to take it out in the sea or lake without a lot of problems at all. Note which parts of the portable fish finder are waterproof and which are not.
Size of the boat: you should know if the portable fish finder will fit well on your boat. Whether you have a kayak, a canoe, a pontoon, a regular fiberglass boat or any kind of boat, make sure that the portable fish finder will be a perfect fit and will not get in the way of your fishing or paddling at all.
Warranty policy: the portable fish finder should also have a good warranty policy. Some portable fish finders are guaranteed to be waterproof so you should ask the manufacturer whether the waterproofing quality is covered by the warranty policy of the portable fish finder.

Other Frequently Asked Questions
Q: What is the transducer in a fish finder and why is it important?
A: The transducer is a component of every fish finder that lets it find fish from a distance of the water of any lake or sea from the comfort of your boat. A fish finder’s transducer is usually made up of piezoelectric crystals, which makes the pretty expensive. These crystals produce sound waves that get bounced back to the unit in case it reflects onto an object, such as a fish or rock or any other object under the water.
Q: What is the difference between a sonar fish finder and a scanner fish finder?
A: A scanner fish finder does what it says it do: it scans various images under the water using the highest frequencies possible, around 455 to 800 kHz so it can scan images similar to an MRI scanner.
In contrast to that, the regular sonar fish finder does not always give you all of the details, but it does give you a lot of good depth, even with a low frequency beam of only 200 kHz or so. It is easy to tell apart fish from the structure and you can go as deep as possible with this fish finder.
Q: Can you change the colors of a fish finder’s display?
A: It depends on the type of fish finder that you have. Some fish finders are grayscale hence there is no color to change. If you do have a colored fish finder in its display, you can be able to change the palette or color set of a fish finder. The ideal tip is to have a white background that is sunlight-friendly and have some sort of sepia or reddish color for you to easily distinguish the fish at the bottom.
Q: Why is a GPS feature important in any fish finder?
A: Nowadays, it is hard to get home without a GPS if you are unfamiliar of a territory. For instance, you go fishing out in the sea and you forgot your compass and your phone does not have signal.
Q: What are the typical bass formations that a person can see in a fish finder?
A: There are three main school formations of bass when you look at them in a fish finder. The explosion formation is something that looks like a scattered thing with no true formation, so it is quite harder to catch. If you chance upon an attack formation, it has a seemingly vertical position of the fish. There is also the wall-to-wall carpet formation, in which a school of bass will go wall-to-wall with another school of fish on a bridge or some other structure.
Q: What is the bottom discrimination feature on a fish finder?
A: A lot of fish finders nowadays have a bottom discrimination feature. It is similar to the discrimination feature of a metal detector such that it breaks up the floor of the sea or lake into various categories such as rock, gravel, sand and mud. It is usually used to determine whether the bottom is hard or soft and is usually used for getting better anchorage for any boat. It can also help most anglers to find out about the bottom structure.
Q: What is a fish arc and what does it tell you?
A: The fish arc determines the speed of the fish that has passed by. The fish arc is the length of time that the fish has passed though the transducer or any device that is currently being used as an observer for your fish finder. A longer fish arc doesn’t always mean that it is a big fish – it can also affect the speed of the fish and will also depend upon the speed of your boat.
Q: What should I do if the fish finder has a lot of clutter on the screen’s top?
A: A clutter on the screen is usually due to the air bubbles that have formed or the bubbles that are created by your kayak or boat. To get rid of this clutter, you can activate the sensitivity time control or STC feature of your fish finder unit to clear it off.
Q: When should I turn on the sensitivity for the fish finder?
A: A fish finder usually goes in the automatic mode for its sensitivity. However, you can easily increase this by turning off the auto mode so that you can manually adjust the sensitivity to your liking so you can get more fish.
Q: What is the depth adjustment on a fish finder and how is it important?
A: The depth adjustment on any fish finder is really important because it helps you determine what kind of fish you will catch. For expert anglers who are specifically looking for a certain species of fish, the depth adjustment is a great feature which should not fail. Some will know the typical depth of the fish they are looking for and set the value to that point in feet or meters.
Q: Why should I move the boat slowly when using a fish finder?
A: Any fish finder will definitely work at its best when you use a very slow speed, especially for trolling. If you want to make sure that your fish finder catches the most important details then you should definitely move slower. A speed of less than 5 mph is the most ideal speed for using a fish finder.
Q: Is a heat detector feature important in a fish finder?
A: This is only applicable if you fish in cold areas or during the winter. Fish will tend to look for warmer places and this is where a heat detector is important for catching fish in the cold. You can also use it for ice fishing because it will be helpful. The heat detector usually goes along with your unit’s transducer.
Q: Why should you install an underwater camera along with a fish finder?
A: Just looking at the fish arch of a fish finder’s screen will not tell you the species of fish that will be seen under the water, whether it is a lake or an ocean. It is important that you use the right bait for the right fish so you may need a camera that works underwater to help you see what’s going on and to know what kind of fish you will most likely encounter.
Q: Is it worth it to spend an entire day looking at the fish finder without fishing?
A: Yes, this is a strategic plan for you to observe the behavior of the fish. In this way, the next time you go to the lake, ocean or body of water, you will be prepared with the right fishing rod, fishing line, lure and other fishing gear and items that are specifically tailored to the kind or species of fish you have just encountered.
Q: Can I detect the wind direction, contours and the air pressure in a fish finder?
A: Yes, some fish finders are quite advanced when it comes to their gear that they are able to detect various data such as moon phases, air pressure, contours, wind direction, tides and the like.
Q: Where should I mount a fish finder on my boat?
A: The fish finder can be mounted in an accessible place that does not get in the way of your fishing or paddling or even your motor if you have one. Most fish finders come with mounts and most of them will be transom mounts.
Q: What are the steep drop-offs in a fish finder?
A: These drop-off locations can be seen in the fish finder and these usually refer to fish-rich areas that are ledges. The bottom structure that is away from the shore will definitely hold a lot of fish depending on your area.
Q: What kind of mounting bracket should I get for a fish finder?
A: You should go for an adjustable mounting bracket so that your fish finder can be moved up or down depending on your needs.
Q: Do all fish create arcs in a fish finder?
A: Not necessarily. Some species of fish such as the black drums will create triangles instead. Some fish are bigger and have odd shapes and speeds which will differentiate them from regular fish.
Q: Can you use old wire from an old transducer to a new one?
A: Yes, if you do have an old transducer from an old fish finder unit, you can use that to connect your new fish finder unit and transducer to the boat of your choice.
