Humminbird Helix 5 Fish Finder comes with a lot of features which makes it one of the best fish finders under $300. You can switch the 5-inch display between full color and grayscale. The backlighting makes the display visible in any light condition. Its SwitchFire sonar system lets you switch the display view from clear to very detailed. The clear mode makes it easier to see fish in rough weather. Max mode provides with excellent detail for a 2-D fish finder. You can even see temperature gradients and currents. The transducer has the power to go 1500 feet deep, but you can get an optional transducer and upgrade it to get down to 2500 feet.

The Helix 5 GPS receiver supports tracking and chart plotting, and you can save your tracks and routes along with thousands of waypoints and fishing spots quite easily. You can attach optional mapping and logging software to it. The Helix 5 has an SD card slot and you can connect it to your PC with the PC connectivity software. You can mount the device in its gimbal frame for a more permanent option. The Helix 5 comes with a new operating system which is quite easy to operate. The small size of the function buttons are the things that we didn’t like much, though the large digit view mode on the display made up for that. This is a good fish finder for the money.

  • Clear imaging
  • SD card and PC software included

 

Things we didn’t like

The Garmin STRIKER series is one of the best fish finders under $300 and is excellent for both professional and weekend fishermen. A portability kit helps you keep the fish finder safe between boats or on the ice. In addition, the 5cv includes a powerful sonar unit and high-resolution display housed in the waterproof rugged IPX7.

This fish finder has a 5-inch color screen and packs almost all of the features of the larger model. In addition, it comes with Garmin CHIRP technology and Clear Vu scanning sonar. The CHIRP transducer puts out a signal in the 77/200 kHz range and sweeps a broad frequency range instead of just a single frequency, and then interprets each level of return separately, which produces clear, crisp fish arches and better target separation. The ClearVu scanning sonar is integrated into the same transducer and shows a wide-angle view of the things below your boat in an almost photographic image.

You can track your location and mark fishing holes for later return with a high-sensitivity GPS. The bottom lock setting shows the return from the bottom to the surface, and the bottom can be 2,300 feet away in freshwater, and 1,100 in saltwater. The A-scope gives you a real-time view of fish passing through the transducer beam. The unit is easy to move, but the side support arms are a little heavier. All in all, the STRIKER 5cv is a great fish finder for the money.

 

Things we liked

  • Generous screen space in an overall compact unit
  • A-scope moving fish tracking
  • Split-screen function

The Lowrance 000-12635-001 is a simple fish finder without advanced navigation features yet popular among anglers. It comes with the DSI skimmer transducer and a DownScan sonar unit that is capable of operating at two different frequencies i.e. 455/800 kHz. The device scans with fan-shaped beams; the 455 kHz beam is wider than the 800 kHz one.

You can amazingly track fish at a depth of 300 feet with this DownScan only device. The transducer with a 6-meter cable and temperature sensor lets you know the temperature of the surface water. You can keep track of organisms at the bottom until the vessel doesn’t exceed 55 MPH. A boat speed of 1-6 miles per hour is necessary for maximum clarity and detection.

Buying Guide for Best Fish Finder under $300

Before you make your final decision on the best fish finder under 300, carefully consider the following three major product qualities to make a smart decision.

 

App Compatibility

We recommend app compatibility if you enjoy keeping track of readouts and building information on your favorite fishing spots. However, if you want to have access to this useful feature, you will need to invest in a product that approaches the 300 price tag limit.

 

GPS

GPS makes it simple to find previous fishing spots on your next trip. In addition, a fish finder model with a quality built-in GPS is necessary if you want to stay protected and informed while tracking fish. Anything too fancy is not necessary but make sure you can easily connect in rural environments, and get home safe and sound.

 

Screen

A fish finder is worthless without a quality screen. Because you won’t be able to understand the readouts you’re looking at without a good screen.

So to make a quality investment, choose a screen at least 4 inches in width having a crisp and bright display. Finally, make sure the screen is easy to navigate.

Color screens are good for identifying fish and the debris efficiently. They can display over 250 colors, which is good for easy identification of things. Combination of the right transducer and the screen will give you the best output.

 

Frequencies

Lower frequency reaches deeper into the water while higher frequency works well in shallow water. Some of the best fish finders allow you to change frequency to fish effectively in both deep and shallow water. So go for the one that meets your requirement.

 

Power

Powerful fishfinder can read the waves under the water and give you clear pictures. The combination of wattage and power is essential to see into the water effectively.

 

Transducer

The transducer sends information under the surface and receives it back. When it receives information, the sonar is sent to the screen and you can see things under the water. You can identify anything when you have the proper transducer.

 

Final Verdict

Fish finders are essential if you want to get back home as a successful fisherman every time you go out fishing. You have to find a fishfinder that suits your needs. The devices we have mentioned above are under 300 dollars and they will help you see more underneath the water than others.
