How to Choose The Best One?

In this section, we will discuss some important factors that you should look for when choosing the right fish finder under 300 bucks.

GPS Facility

Choosing a fish finder with a built-in GPS has no alternative. A good fishfinder GPS helps you pinpoint your correct fishing position and note the fishing spots you want to return later. So, we highly recommend you to buy a fish finder with GPS capability.

Transducer’s Beam Angle

The Beam angle is also known as ‘Cone angle’. Beam angles of the transducer is one of the crucial factors for every fish finder. Beam angle determines how much underwater area coverage you will get from the transducer.

A large beam angle allows you to cover more area underwater. And of course, the more area covered by the beam angle, the more chances you have to catch a fish.

So, always look for a fish finder that comes with a high beam angle featured transducer.

Water Temperature Detection

If you want to fish certain types of fishes, you must choose a fish finder with water temperature detection capability. Because every fish like to stay in a certain water temperature environment when they feed.

Some fish stay in cold water, and some fish will be found in warm water. So, when you go fishing a specific type of fish, you first need to know the temperature of the water.

CHIRP Sonar

Compressed High Intensity Radar Pulse (CHIRP) is one of the latest additions in sonar technology. And it would be best if you always prefer the upgraded version when buying electronic equipment. So, try to choose a fish finder that comes with the latest CHIRP sonar technology.

Typical sonars send a single frequency beam. But CHIRP sonars can send beams with multiple frequencies. And diversity in frequencies means better images. That’s why we highly recommend choosing a fish finder developed with CHIRP sonar.

Down-scan Imaging

A fish finder with down imaging capability gives you more clear data and more detailed images underwater. It allows you to know the circumstances under your boat. Also, down scanning is very helpful for detecting underwater structures more clearly.

Frequently Asked Questions

In this section, we will compile some common questions and relative answers that may be helpful for you –

Q: Is It Difficult To Change The Sonar Battery?

Not at all. Follow some easy step to do it – open the battery cap and slide the black tab that holds the battery backward. Remove the old battery and insert a new one. Ensure that the battery is placed well. After inserting the new battery, close the battery cap again. Finish!

Q: Can I Sync Fish Finder with My Smartphone?

In some finders, you can. In the last few years, most of the fish finders come with an app that you can install in your device and sync the fish finder with your tablets or smartphone via this app.

Some fishfinder has built-in Wi-Fi, and you can connect the fish finder with your devices by using the Wi-Fi.

Q: What Is The Difference Between A GPS And A Chartplotter?

GPS detects your location, but it doesn’t have any mapping system to point out the locations. But a Chartplotter is a combination of both a GPS receiver and a map. It shows the GPS locations in the form of a map.
