How to Choose the Best Fish Finder for Crappie

The following are the features that you should look for when buying a crappie fish finder.

1. Display Specs

The display is the most essential part of the fish finder.


The first thing that you should keep in mind is the size of the screen. Most fish finders have a screen size of 4-inches to 12-inches.

You can purchase the one that is according to your preferences.

A larger screen is better than a smaller one. It is easier to locate information on a larger screen.

On the other hand, larger screens are expensive as compared to smaller ones. So, the choice depends on your budget.


The pixels of the screen determines the quality of the picture. The screen resolution is the most essential aspect of fish finder.

A higher pixel specification helps you see the fish and other objects more clearly.

However, the higher the pixel rating, the higher the price will be. So, you will need to make a compromise between the price and screen resolution.


Another feature of the screen is the color. There are two types of displays: colored and black and white displays.

Both types of displays have their pros and cons.

Colored displays are easier to see in bright sunlight. Also, the colored displays can help you differentiate between the different shades.

On the other hand, black and white screens are cheaper.

2. Transducer Specifications

The transducer is the part of the fish finder that sends out the actual pulses that help to locate fish.

Transducer Power

The first factor that we must consider the transducer is power. The power is what determines how well the transducer works. A good power transducer will help to differentiate between different structures underwater.

You will find the power rating in watts root mean squared. A 500 watts transducer is a good one to start with.


The frequency of the transducer is another essential factor that you must keep in mind. A higher frequency translates into better detail and provides a better-detailed image.

However, a high-frequency transducer cannot ‘see’ deep into the water. On the other hand, a low—frequency transducer can penetrate much deeper in the water. However, in a low-frequency one, the image will be less detailed.

So, you need to make a compromise between them based on your needs. 200kHz to 800kHz is good frequency if you want to fish in shallow water and 50kHz to 80kHz for deep water.

CHIRP (Compressed High-Intensity Radar Pulse) is the newest addition to fish finders. These devices can send multiple frequencies at once.

However, this advantage does come at a high cost.

3. GPS

GPS or Global Positioning System is another feature that is necessary for fishing for crappie. A GPS device can help you trace your route and save your favorite fishing spots.

4. Cost

The cost of the fish finder is another factor that is vital to consider while purchasing the fish finder. However, there is a difference between being an important feature versus being the most important feature.

A fish finder is an essential tool that fishers in the past could only dream of having. Buying the best fish finder for crappie will enhance your fishing experience.

Therefore, it is important to look at the features before purchasing a fish finder.


If you plan to catch crappie this spring, get Raymarine Dragonfly 7 Pro. The high-performance and reasonable price make it the best fish finder for crappie.
