Q: How does a portable fish finder work?

A: A fish finder works through sonar technology that is able to detect fish through the use of sound waves in the water. The fish finder device is able to communicate these signals into the water and display its results on the screen. Portable fish finders are unique because they don’t need to be wired and connected to a boat. They are easy to transport and can be suitable for almost all different types of fishing experiences. A portable fish finder can run on batteries and be stored in your tackle box.

Q: Castable Fish Finder vs. Portable Fish Finder?

A: It really depends. While the portable fish finder is more common, it really comes down to what you are comfortable with. Personally, I try to avoid a castable fish finder while I am on a kayak or canoe because I want to have my fish finder close to me. Usually when you are on a kayak or canoe, you do not need to cast far away from your location, so a portable fish finder is perfect for me in identifying what is currently swimming under my kayak. However, both have been proven to work.

Q: Are portable fish finders waterproof?

A: Unfortunately, not all fish finders are waterproof. While most fish finder devices can handle water splashes, they weren’t made to be completely submerged under the water. They should be able to handle rain and waves, but try to avoid dropping these expensive devices in the water. In the worst case scenario, rice has been an effective method in reviving portable fish finders that fell victim to falling into the water. Dry rice is an effective way to absorb the moisture in the device. 

Q: Are portable fish finders weaker in power compared to a traditional fish finder on a boat?

A: Given the difference in price, you may think so but the power is fairly similar. Outside of the lower quality portable fish finders, most are just as powerful as the typical fish finder that you may find on a fishing boat. The sonar technology between the two does not change. The way that the information is displayed on the screen can vary between products, but the power remains constant. 


While a portable fish finder can help yield better results when you are fishing, the most important determinate is the angler. Fish finders help create a strategy but they don’t necessarily produce the end results. They will help you better understand the waters that you fish, which should eventually improve your fishing abilities. If you haven’t tried a portable fish finder before, imagine knowing exactly where the fish are around you. Not only is it great for fishing, but the principal itself is pretty cool.
