Fish finders are essential tools for detecting fish and other submerged structure that would otherwise be unable to be seen by the eye. Utilized by anglers, commercial fishermen, hobbyists, and even just recreational fishers at the edge of a pond, fish finders are gaining popularity rapidly. With the rate of modern technological advancement, many new useful features are available, and so many models are on the market.
A fish finder’s transducer is typically large, making it nearly impossible to transport from time to time. If you have two different boats, one relatively small one and a second larger one, it would be nice to only have to buy one fish finder that would work well for both. Another scenario; perhaps you don’t live near any sizeable ponds, lakes, or rivers. Instead, you decide to occasionally take trips out to the Lake Lanier region in Georgia during the season.
You can’t really bring your own boat, so you decide to rent a nice but small 10-foot fishing kayak when you get there. In both these situations, a portable fish finder would solve the issue.
Portable fish finders generally have higher mobility, are smaller in size, and are perfect for quicker trips and smaller watercraft. Because of their reduced size, however, there may be a significant difference in power and overall performance. As technology advances, more features are being presented to the market of portable fish finders. This article will aim to give a basic top ten lists to base your research on, and clear up some confusion about best portable fish finder.

DownVision and CHIRP sonar technology are both innovations that are made to allow users to receive better, clearer, and more accurate readings. CHIRP sonar technology emits more sonar waves and reads responses more often, meaning you get a more consistent and precise result.
The Dragonfly 4 also comes with built in wifi, and connectivity to the special Raymarine Wi-Fish smartphone application. The Wi-Fish app allows users to review results, save snapshots, and share media to other websites. The Micro SD card slot also allows for media to be saved and sent to friends. The 4.3 inch backlit display can withstand harsh weather conditions, and is engineered to provide a wide viewing angle. The Dragonfly 4’s advanced transducer has outstanding depth performance of up to 600 feet.
The only problem with this model? It is another fish finder that is technically not portable. It has many options that may allow setup time to be reduced, or even eliminated, but the Dragonfly 4 is traditionally a mounted model. Another transducer may be purchased, but many of the specifications available for the original transducer are not featured in removable models. The Dragonfly 4 is another great fish finder, but it is a little more complicated and is not suggested for amateur use.
«3» Garmin EchoMap 44dv
The Garmin EchoMap 44dv is a nice simple mounted model with the advantage of GPS. Though it is not a portable model, it is a versatile and mobile fish finder. The entire selling point for this product is that it isn’t a $*** fish finder, but still has advanced maps and GPS location services.

The Deeper is great for anyone who really wants the most portability, and is willing to sacrifice a bit of functionality for it. Deeper can make anglers lives much easier, whether they consider themselves recreational fishers or professional anglers.
Considerations for Purchasing Portable Fish Finders
Portable fish finders are extremely useful on small watercraft, like kayaks or v-hull boats. Using a fish finder may be a bit overwhelming, especially if you have never seen one of devices in your entire life. Portable fish finders aren’t only confusing for amateurs or first time fishers; there are some aspects that may even mess up professionals that have been using traditional fish finders for a large portion of their lifetime. This will aim to clear up a few problems that many people have with portable fish finders and walk user through utilizing fish finders on kayaks.
√ Transducer Types
The first thing you need to consider when buying a fish finder for kayaks and small boats is transducer size and type. Several fish finders on the list above have stock transducers that are meant to be mounted, rather than moved at the users will. Luckily, more and more companies realize the importance of detachable transducers, and allow customers to purchase portable or ‘quick release’ transducers and displays. There are several types of transducers: transom mount transducers, in hull mount transducers, and through hull mount transducers are the three most common mounted transducers. These transducers are made to permanently be attached to the watercraft. A transom mount transducer is the most common type of transducer that comes with fish finders. These transducers are placed on the transom, as the name suggests, and are made to be completely submerged. While these are the most common, transom mount transducers are also the cheapest type and are most often constructed of plastic and less expensive materials. Transom mount transducers are good in most situations, but fall short when bubbly, choppy, or unclear water passes them. Therefore, you should avoid using these types of transducers at high speeds if you want accurate readings. These are the easiest types of transducers to mount, though they are still mounted.
Through hull and in hull transducers are more permanent than transom mount transducers. In hull transducers are glued to the hull, and are also made to be submerged. These are permanent transducers that don’t require holes to be drilled into the hull if the watercraft. Faster boats, like sail boats, often utilize in hull transducers because they don’t stick out into the water, and no resistance is made by these transducers. Installation and maintenance of in hull transducers can both take place in the water. The downside to using in hull transducers is that they are only made to penetrate fiberglass – metal, wood, and even porous fiberglass can’t be used due to the fact that the sonar waves are shot through the hull. Unlike transom mount transducers, in hull transducers excel at giving high speed sonar readings. Through hull transducers require the most amount of labor in order to install. The hull must be drilled through for this type of transducer to be mounted. Fairing blocks are required for some through hull transducers, so the downsides for these transducers are extra cost and tricky installation.
Most of these transducers will not work for kayaks or other smaller vessels. You may want to research the several types of portable transducers. Some portable transducers, like the Deeper Smart Fish Finder, have multiple applications and can be used for almost any scenario. Others, however, are more suited for single purposes. Some portable transducers are cast-able, so they can be attached to a line and sent farther out. Others are specifically designed to withstand all weather conditions, and can be used for ice fishing. A few portable transducers even come with suction cups and screws, so they can act as a temporarily mounted transducer. Any of these transducers will work, but it is more about which best suits you and your setup.
√ Display Type
Another important thing to consider on all fish finders is how the data is displayed. Most modern fish finders will either display sonar reading as curved lines, or as fish icons. Arch fish finders display the raw data – no icons, no structure, just arches. Fish ID will show rocks, vegetation, and other waterbed objects, as well as showing fish icons. While some fish finders can switch between these two display types, or even display them side by side, those are typically the higher end models. Arch fish finders do take longer to adapt to. The raw data is not as convenient for beginners and recreational kayak fishers, but it is far more accurate in most cases. Often times, Fish ID will mis-identify or mis-label objects, calling vegetation a school of fish or other significant errors. Fish ID is also more expensive in most cases. In the end, it all comes down to preference; are you looking for an easy experience, or are you willing to invest time to learn how to read a more accurate interface?
This list is designed for generous purpose fishers that want maximum mobility, and would prefer ‘true’ portable fish finders. Depending on your specific needs, other fish finders may be better. The best fish finder on this list regarding features, price, and overall specifications would be the Elite 3X portable pack, but because it is not a true portable fish finder it came in second place. The Raymarine Dragonfly 4 Pro is also another great fish finder – it’s just not mobile enough. The Deeper fish finder can be used for kayak fishing, shore fishing, ice fishing, bay fishing, angling, and several other applications, and is extremely portable. This is why it received the number one spot. There are several fish finders on the market, this list was made to help you narrow down your search for the perfect one for you.
Reading fish finders is perhaps the most important factor of buying one; if you can’t read one, it doesn’t matter how much money you spend on one. Transducers types are also essential to understand, because you wouldn’t want to purchase a fish finder just to find out it was not the optimal transducer type for your vessel. To better understand fish finders and their functions, you can look at this Youtube video. Hopefully this article has cleared up some confusion, explained some terms, and helped you on your journey to purchasing a fish finder.
