Types of Fish Finders
Standard Sonar
Standard Sonar sends waves into the ocean that bounces. A bounce indicates a fish or a structure. Sonar helps you to determine when you should throw your fishing line.
The problem with this sonar is the accuracy of the location. It is a depth finder, but there’s no assurance of how accurate it is. The screens in these are not detailed.
Chirp Sonar
CHIRP uses sonar frequencies. Instead of sending equal waves in a pattern, the chirp sends a quick burst of sonar waves.
This helps to detect the fish a lot faster and also increases the accuracy. They can also tell you more about the water structure.
Down Imaging
Down Imaging paints a vivid picture of what to expect beneath the water based on the frequency. It provides a detailed picture of underwater structures and refreshes constantly. This is a lot more accurate than the first two.
The cons of having this sonar are they can only tell you what is directly beneath the boat. It is only limited to what you can do with this type of finder.
Side Imaging
Side Imaging helps you to see what’s around the boat rather than under the boat. It is a lot more helpful when you are trying to fish around you or in shallow waters.
Fishfinder brand manufacturers advanced their devices with this kind of imaging.
What to Consider When Buying a Fish Finder
Mounting
One of the important factors is how you can mount it to the boat. The typical type of mount is a transom mount transducer.
It is mounted to the back of the boat by the trolling motor. Always be aware of it, so you lose it in the middle of the water.
Display
The display helps you see what is going on beneath you. Most fish finders that you can see today use full-color displays to signify elevation changes.
This feature is useful when catching fish. Consider a display that is good with direct sunlight.
Cone Angle
Refers to the width of the sound wave that it offers. The wider it is, the larger the area. Find one with at least a 20-degree angle. It is the most common angle that you can see in a fish finder device.
Size
In looking up at a device, you should consider its size. When you have a small boat for fishing, you should get a size that would fit in your boat.
But also, getting a smaller screen size may make it a little difficult to see what’s happening under the water.
Power
A powerful device can help you to enhance your fishing style. Power can enhance the fish finder features, especially when fishing in deep water or long.
GPS Capabilities
Knowing your device’s GPS features and capabilities allows you to create waypoints and document your best fishing spot. It can easily point you where your desired fish might be.
Frequency
Good fish finders have a good frequency. A quality frequency and a moderate power are essential for getting a high-quality picture of the water.
Transducer
Determines the quality of the image that you will receive. Getting a great fishfinder transducer is a must. If you don’t have a high-performing transducer, you won’t have the accuracy to find anything.
Target Separation
Target separation distinguishes individual fish from another. Smaller numbers mean that you have better performance.
Final Verdict
Having a fish finder can give you the edge you need when you’re out fishing. Consider using this article as a guide to determine the best fish finder for you.
Make sure you check the fish finder reviews thoroughly. Once you’ve got one, get ready for a big catch!
