You know that you have the best bait, the best fishing rod and are in the most prime area of the lake. The only problem is that it seems all of the fish have gone into hiding. What’s worse is that the water is too murky to see.
If you have never used a fish finder, you’re missing out on a hell of an experience. It helps you locate where the fish are hiding by scanning the waters and pinpointing their location in proportion to where you are. It can tell you how deep it is and in some cases, the temperature of the water. In this post, we review the best fish finders and tell you how to choose one that suits your needs.

How to Choose the Right Fish Finder
There are several factors you should consider to choose the best fish finder. Some of them are discussed below.
With increased wattage comes faster time response. A fish finder that has more wattage also makes it easier to see deeper in the water and find the fish. If you will be fishing in shallow waters, a finder with less wattage will be better. Depending on the frequency range, you will readings from 100 feet deep to more than 400 feet deep.
It is important to understand the significance of the frequency range when looking for a fish finder. Frequencies come in three types including single, dual and multiple. They come in 50, 83, 192 or 200 kHz. The higher frequencies are ideal for fishing in shallow waters while lower frequencies like 50 and 83 are great for deep water fishing. The higher the frequency, the more detail you will be able to see.
A transducer makes it possible for a fish finder to actually find fish in the water. It emits and receives sonic waves that let you know if there is any fish nearby. Once it receives the data, it sends it to the main unit before switching it to the screen. Without this feature, your fish finder is simply a fancy screen.
Every fish finder has a transducer but it’s always good to purchase an after-market transducer. This is because after-market transducers are designed to read a wider area, receive data faster and generally work better than what comes with a fish finder.
Color screens allow for greater detail in millions of colors as compared to 256 shades of gray. They are the new standard when it comes to fish finders since they make underwater life really pop out at you. It makes it easier for you to see what’s going on, especially in bright light or when the weather is cloudy and dark.
While black and white models are still available on the market, using them won’t be as enjoyable as a color screen. We would recommend one if your budget doesn’t allow you to purchase a color finder.
Another important factor to consider is the number of pixels on the screen. The higher the number of pixels, the more details you will be able to see. You want to ensure your fish finder has, at the minimum, a resolution of 240 x 160 pixels. Even then, images will not be very clear. Consider spending more on a higher resolution screen.
The screen resolution combined with the screen size will be the ultimate factor that determines the clarity of the display. While smaller screens are good choices for backup or secondary fish finders, purchasing the biggest screen with the highest resolution you can afford makes more sense.
Choosing a fish finder is easy if you know what features to look for. All of the models reviewed above are highly rated and have predominantly positive reviews from customers. The most important thing when making your purchase is to ensure that the fish finder you choose suits your needs. Don’t hesitate to tell us more about your favorite model and why you love it.
