The scanning depth range of this Garmin fish finder will vary, however, for a budget scanner it’s pretty powerful. If you’re fishing in clear freshwater, the sonar technology can pinpoint stumps, docks, and ground contours up to 1600 feet deep.
For saltwater, you will be limited to a 750 feet distance potential. Once scanned, the display on the screen is shown in a vertical format which many anglers say is much more desirable than horizontal.

Finding a highly portable fish finder that also falls under the $300 price point may be difficult. However, the Deeper CHIRP Smart Sonar fish finder is exactly that.

What to Look For in Fish Finders Under 300
A number of beginner and professional anglers will find one brand and stick with it. If you enjoy their products, there is very little reason to go elsewhere. With fish finders under 300, there are a number of different brands on the market today.
Whether you are looking for a budget model or are prepared to splurge for the perfect technology for your next fishing expedition, some of the most well-known names in the industry today are Humminbird, Lowrance, and Garmin.
Each has its strong suits, and a few weaknesses, so be sure to take into account their other products in higher and lower price points to see how they stack up. For example, if a highly accurate built-in GPS is your main goal, Garmin should be considered.
If instead, you would like to focus on the clearest sonar imaging available, Humminbird should be your go-to.
There are some lesser-known brands as well which have not yet made a solid name for themselves in the fish finder market. This includes Vinterior and Phiradar to name a few. You may end up loving the features one of these less-represented brands offers, so don’t be afraid to give them a try.
The two standard options you will find on most fish finders are Down Scan and Side Scan. These both offer a unique but highly detailed view of the underwater world to help you gauge whether or not the location you are in is worth remaining in for a day of fishing.
Side scan is a sonar that scans either side of your boat or vessel at an angle toward the bottom of the lake or waterway.
It is great for giving you a view of the ground contour as well as underwater obstacles such as stumps, pylons, and more. Additionally, it can help you locate schools and arches of fish that may not be directly below your boat, letting you know whether or not you should cast off one side or the other when fishing.
Down scan is a sonar that scans directly beneath your boat or vessel in a cone or triangle shape. It helps build a detailed picture of the potential fish below your boat as you move forward, especially if it’s paired with side scans.
The down scan sonar is sent in small bursts rapidly and as the data return to your fish finder receiver, it forms images of underwater objects and fish on the display screen. The better the resolution on your fish finder display screen, the better the results of your images and 2D radar results helping you decide which location is a promising fishing spot.
Most anglers, both novice and experienced, will try to find a fish finder that offers both scanning options. Being able to use both side scan and down scan data when compiling your waypoints is highly valuable in finding the perfect fishing location.
A transducer is the part of the fish finder that makes everything work together. It is the main piece of technology responsible for sending and receiving waves of data from the sonar pings.
As the waves bounce off fish, objects and the ground that are under the water, they return to the transducer to create an image of the item or contour of the ground to help you know where to turn for finding fish.
As you adjust the frequencies of the sonar, the picture you receive can become much clearer and easier to decipher.
A transducer is installed on your boat, and there are various kits on the market to help you install it in a suitable place. Depending on your specific transducer, some installation locations may be better than others.
Be sure to check the manual and see what it suggests. Transducers are made in a variety of materials, but for most budget fish finders you will see high-durability plastic as the material of choice.
When it comes to the most affordable and budget-friendly fish finders, finding one that does not have built-in GPS capabilities and vast amounts of preloaded charts may help save some money.
However, there is still a wide range of affordable and extremely versatile fish finders under 300 that do include built-in GPS and preloaded chart features. Some lesser-known brands such as Vinterior and Vexilar can offer standard GPS with less accuracy than better-known brands such as Garmin and Lowrance.
Additionally, some of the better brands to search for with navigation features that still stay under the $300 threshold are the Lowrance Hook Reveal or the Garmin Striker line of fish finders. You’ll find accurate and reliable real-time GPS tracking, waypointing, and a variety of bathymetric mapping options including QuickDraw or Genesis.
Finding networking features on budget fish finders, such as WiFi, Ethernet, NMEA support, or other online connectivity may not be the norm within this current price scale. You may be able to find one or two models with basic NMEA 0183 networking features but it will be right at the higher end of the $300 limit.
Final Thoughts on Best Fish Finders Under 300
The quality and reliable nature of fish-finding technology have improved by leaps and bounds over the past several years. Compared to some of the earlier fish-finding options, today’s selection is vastly improved.
Better and more accurate GPS pinpointing is improving as time goes on, as are the CHIRP sonar technologies and the distance they can reach to the sides as well as below your vessel. You’ll also find a wide range of fish finders that offer some of the most capable down imaging and side view sonar available today, even on budget models.
Regardless of your chosen price range for fishing technology, there are many devices that can offer the high-tech capabilities you want to help improve your angling results. Whether you go with the Helix 5 or a Lowrance model, you are sure to notice improvements in your fishing locations as well as the fish you are able to land when using the devices.
For shore fishermen, kayakers, and ice anglers, using a fish finder that works in your chosen location can be an outstanding benefit. For one, you’re able to see exactly what’s under the water or ice, as well as how productive your fishing trip may be.
Once you know what features you are looking for, and what is most important to you when it comes to the right fish finder, getting one that meets your exact needs without going over your budget is very possible.
Hopefully one of the above-reviewed fish finders on this list helped you make your selection, or at least point you in the right direction for a different model.
