How to Choose the Best Sonar Fish Finder

Power

The power of the fish finder is described as “watts”. When a seller is describing a fish finder’s overall output power, they will often refer to it as “peak to peak performance”. When you’re looking for the best sonar fish finder, you want to make sure it is powerful enough to handle any depth you’re fishing.

If you’re not getting enough power to the display, you’ll have delayed action times, which won’t help when you’re trolling. Fish finders should be at least 800 watts, but you can find fish finders with wattage over 3000 watts. The environment you’re fishing in will determine which fish finder will be the best for you.

Pixels

When you need clarity for your fish finder’s display, you need to make sure it has the right number of pixels. Since the display screen is made up of thousands of tiny pixels, the higher the pixel number, the images will be more clear.

If you’re looking for the best finder, you want to make sure the pixels are at least 240 x 160. You can move higher once you’ve become more comfortable using the fish finder. It can take some time to learn, but once you become comfortable with it, you can adjust the fish finder to your preference.

Transducer

The transducer is what sends out the sonar signals into the water, which are sent back to the transducer. The transducer will take the readings, and send them to the display screen. Transducers can be difficult to place on a boat, especially if you’ve never attached one before. A transducer should be out of the waves of splash back from the motor, and the transducer should have a wide cone.

The wider cone allows more images to be picked up, which helps when you’re trying to find the fish. There are different degrees of transducers including: 9-60 degrees. The transducer also allows you to fish in deep or shallow water, as well.

Side Scanning

The fish finder should have a side scanning technology, and most of them have some sort of side scanning ability. The side scanning allows you to see objects directly to the side of the boat, which makes it easier to find fish.

The images from the side scanner are clear, and you can see everything around you. Even if you’re fishing in murky water, the side scanner will cut through the water to give you an excellent picture of everything in the water right next to your boat.

Display

The display is the most crucial part of the fish finder, because if you can’t see what the transducer is picking up, you won’t have success. Most fish finders have colors, which makes it easy to determine what is a fish. While you can find some with a black and white feature, but you are better off with color.

When you’re looking for the right screen, you should consider the size of the display screen. The larger screens allow you to find fish a lot easier than using a smaller screen.
