Best Fish Finders Under 300 Reviews

1. HELIX 5 CHIRP GPS G2 Fish finder

The Helix is a series of trusted fish finding GPS’s from Humminbird. It is one of the most technologically advanced fish finders that you can buy on the market, but is it worth the money?

It’s sonar technology, for one, is unprecedented. The CHIRP sonar that is built into this unit can allow you to detect where fish and other life forms are at high, medium and low frequencies.

With “Dual Beam” technology, you are able to also scan the water underneath your boat. It’s two beams can help you detect objects more accurately, just like how you need two eyes to see better.

It’s technology can also allow you to plan, chart and map efficiently, so you can plan your trip on the water from start to finish. You can save up to over 2700 waypoints among 47 routes and 50 tracks. It’s much like a journal in a sense that it can store information about fish as well as where the fish finder has found it.

This is also a very easy to use fish finder that you can easily read and understand, as well as where to navigate.

The Helix 5, however, does not come with a cover. You will have to buy the cover separately, and for a nice piece of tech like the Helix 5, you would appreciate it coming with some layer of protection, but that is just not the case.

How to Choose the Right Fish Finder Under 300


The frequency range on a fish finder is important to know. When it comes to frequencies, the lower the frequency, the more likely they are reaching deeper into the water. The higher the frequency, the better the fish finder is in shallow water. Some of the best fish finders allow you to change from high to low frequency. If you’re planning on fishing in different areas, you should get a fish finder that can handle multiple frequencies.


Fishfinders run off wattage, so finding the right wattage will help you find the right one for you. You want a fish finder that is powerful because it can read the waves and everything under the water to give you a clear picture. The combination of wattage and power allows you to see down further into the water. For example, using a fish finder with 100W at 50kHz allows you to see down to 450 feet under the surface.

Screen Resolution

Depending on how many pixels you get, the resolution may or may not be as clear. For the minimum number of pixels, you should get a fish finder at 240 x 160 pixels. While this is the minimum you want, you should be able to find one that works better than that. You can find the screen resolution on the product, allowing you to make the right choice for you.


The transducer is what sends and receives information from under the surface. You can install a transducer on your boat, and some of them have kits to help install them. When the information is sent back to the transducer, the sonar is sent to the screen. This is how you can see what’s under the water. You can pick up just about anything when you have the proper transducer for you.

Color Screens

While most fish finders have color screens, you can find some that still use a black and white feature. Depending on your preference, you can find the right screen for you. Color screens are ideal for picking out the fish and the debris in your location.

Most color screens can display over 250 colors, allowing you to pick out everything easily. When you combine the right transducer with the screen, you can easily pick out what is debris and where the fish are. Color screens provide the best chance of catching a fish since you can tell where they are located.

Who Needs the Fish Finder and Why You Need It?

Anyone who loves fishing will appreciate a fish finder. They are easy to use and provide you with the best information possible. Not only can you learn a lot about the contours of the bottom of the water, but you can also map out your location. They’re ideal for anyone who loves the outdoors and wants to get a better idea of their surroundings.

A fish finder is an excellent tool that can help you track fish. Not only can you track the fish, but you can also use the fish finder to find your favorite spots. You can always come back to it later. A fish finder provides the excellent information you’ll need to help you have a successful fishing trip.

Final Verdict

Fish finders are ideal for those wanting to get more information about their favorite fishing spot. If you’re a fisherman or kayaker, a fish finder makes a lot of sense. There are plenty of fish finders available, but you should find one that best suits you and your needs.

If you’re thinking about getting a fish finder, the HELIX 5 CHIRP is an excellent choice. You can see more underneath the water with this fish finder than you will with others. For less than 300, you can’t get much better than this one.

Whether a good fish finder can be a great asset for finding fishes with helping to locate fish. The increased amount of money can be a problem. I think the 300 margin is good enough to spend for finding proper fishes. Thanks for the information and guidance.

    This device uses high-precision GPS, which allows you to track accurate locations and check the trolling speed for certain baits and fish targets. Thus, using the Striker v with trolling motors will be remarkably easier. The Striker v’s waypoint map feature lets you mark and map your fishing spots, docks, brush piles, and stumps.

JOEL - January 8, 2018

I am looking to be able to move the fish finder from one boat to another. Is the Garmin Striker set up so a person could unplug the transducer and power… and purchase another transducer and power supply to install in the second boat?

If not, do any of these have that option?


    James Williams - January 9, 2018

    Yes, You can use existing one.
