Best Fishfinder Buyer’s Guide

This buying guide for fish finders uses some common terms that you will encounter thousands of times while reading the article. 

Here are some of the factors that you need to consider that will make your decision about buying a dish finder easier.

1. Transducers

Transducers are an integral part of every fish finder. These are used to send as well as receive the sonar waves. Transducers are responsible for making a difference between poor and quality fish finders.

Once the waves emitted in the water, it bounces off different objects. The transducers read these waves. The data gets in the central processing unit, and it gets processed as a picture in the display.

Powerful transducers result in better image quality. Stronger sonar signals are emitted by powerful transducers that reach greater depths.

2. Cone angles and beams

At the time of choosing a transducer, you need to consider the cone angle. The cone angle gives you an idea of the width of the beam that gets emitted from the boat to the water – a wider cone results in covering a larger portion of the area. 

The angle of the cone expands as the beam moves downwards in the water. But, all these happen at the sensitivity of the depth of the water. The cone of transducers ranges from 9 to 60 degrees.

3. Screen resolutions

While considering the display of the screen, you should look at the number of pixels on the screen of the fish finder. The more pixels on the screen, the more details you will get on the screen.

If money is not a factor, you should choose a fish finder that has a high resolution. The screen size, along with the resolution, decides the quality of the picture. If money is a factor, then you should not set for a device having less than 240 X 160 pixels.

4. Water resistance

It does not matter if you are buying a high-end model or a budget model. Water-resistance is very important. Before buying, you must check the IPX and JIS ratings. Both of these are quite similar, but the rating identifies the level of resistance towards the water.

A 4-rating device can resist itself from splashing water. A 6 or 5-rating device can stand low and high-pressure water. A 7-rated device can submerge itself in 10 feet of water for around 30 minutes. An 8-rated device can stay submerged for a long time.

Conclusion

After doing extensive research, the best 7-inch fish finder is quite difficult. You need to have proper knowledge as well as experience in using fish finders. Only then will you understand what it is you want in your fishfinder. 

Fishfinders allow you to identify and search fish and what is going on under the boat. Before buying a fish finder, you must understand your requirements, budget, and what features you want in your device. 

My recommendation is the Lowrance Hook Reveal 7 Fish Finder 7 Inch Screen. It is a very versatile piece of equipment and it can be of great help while fishing.

I hope that this guide on the Best 7-inch fish finder provides you with all the information required to buy a fish finder.
