A Fish Finder is a device that features a highly intelligent Sonar Device. This technology continuously sends out pulses of sound waves, and these sound waves are directed towards the bottom of the lake, river, or ocean that you may be fishing.
When these sound waves or pulses strike objects like fish, structure, vegetation, or the bottom, they are reflected back to the surface. The sonar captures all the information, stores it, and displays the information in a two-dimensional view, which can easily be interpreted by fishermen. As the size or shape of the object changes, the pulses of sound waves received back by the sonar will be shorter or longer.
By mapping this information together it allows the program to illustrate the objects that are below, therefore enabling anglers to identify and catch more fish.

Best Fish Finder under $500
Garmin Striker Vivid 7 SV
Garmin has been making quality Fish Finders for some time now and has earned a well-deserved reputation for quality and innovation. For good reason, this Striker Vivid SV is thought to be one the best value for money Fish Finders on the market for less than $500.
It features a fantastic 800×480 pixel screen that is seven inches wide. This is a good size to view the quality SideVu imaging Sonar, standard two-dimensional Sonar, and Clear Vu Chirp. The sonar operates at a frequency of 150 -240kHz, The Clear Vu operates at a frequency of 425-485kHz, 790-850kHz and the SideVu operates a frequency of 425-485kHz, 790-850 kHz.
This Fish Finder features Wi-Fi, an internal GPS but unfortunately isn’t equipped with a microSD memory slot. This means that upgrading map capabilities are limited.
- Large seven-inch screen – This screen is up to 40% larger than some competitors, and offers beautifully detailed images which are easy to see
- Side Vu Imaging – This a mode of Sonar Operation that allows you to differentiate between texture types and materials on the bottom. It offers an underwater view of the waterway to the sides of the vessel, this image is similar to an aerial photograph and gives one a good understanding of what’s below
- Chirp Technology – Chirp Technology exceeds most common limitations of single frequency Sonar. Chirp continuously sweeps through the range of frequencies. Chirp is an acronym for Compressed High Intensity Radiated Pulse. Chirp Fish Finders transmit a significantly longer pulse than traditional Sonar
- Wi-Fi – Wi-Fi allows anglers to stream Sonar Data directly to their phone or tablet
- Not having a MicroSD means you cannot upgrade maps

Fish finders Buyers Guide
When purchasing a fish Finder there are numerous factors to consider. There are vast amounts of technology packed into these units and at times it can be overwhelming, even confusing. Even if you are an old-school angler or prefer the traditional methods of hunting your fish, a Fish Finder can be extremely useful. So what should you consider?
This is no time to economize, there are numerous Sub-Standard Fish Finders on the market that appear to be affordable. Try to avoid these, and support reputable manufacturers. Their units are also affordable but more importantly, they are reliable.
At the same time, there is no need to over the top and spend large amounts of money purchasing a Fish Finder you won’t fully utilize. Check the features, benefits, and accessories of each Fish Finder, and decide on which functions you might use when deciding on your budget.
COLOR SCREEN VS BLACK AND WHITE SCREEN
Black and White Screens can be difficult to read, particularly in overcast conditions and in direct sunlight. Most modern Fish Finders are equipped with Color Screens, which results in a significantly improved image of what’s below.
It is imperative to check the screen resolution before purchasing a Fish Finder. The minimum resolution should be 240×160 pixels. This will offer a decent image, but it might be a good idea to go as high as your budget allows. A higher resolution will give you a much more detailed, crisp, and clean image.
A quality Fish Finder should have a quality GPS. It is vital for underwater topography and to download maps. GPS allows you to mark points, which you can return to on a future fishing trip. If you happen to be tech-savvy, a Fish Finder with Wi-Fi will allow you to connect to your phone, tablet, or any other device. Usability and convenience will dramatically increase, and data recording will be significantly easier.
The accuracy of a Finder is important, for obvious reasons. The key is a quality Sonar, check the cone angle to ensure it has a range between nine and sixty degrees. Once the sound waves are emitted from the transducer, they move towards the bottom and expand as they travel further. This spread is measured in degrees and twenty degrees is the most popular choice.
A Fish Finder mounted to a bass boat will face very different conditions, when compared to one that is mounted on an offshore Kayak. So depending on your method of fishing, water resistance is something to consider. If your Fish Finder is going to be mounted on a ski-boat or kayak, then an IPX7 rating is required. Check the IPX ratings, the higher the IPX number, the greater the level of water resistance.
It is vital to know how to effectively use your Fish Finder to maximize your fishing experience. If you aren’t technologically driven, a Fish Finder with automatic settings might be easier to operate. Some also offer displays that can be enlarged for easier reading. No matter what your preferences or requirements, there is a Fish Finder for all types of anglers.
Each and every one of the Fish Finders mentioned in this article is made to the highest standards. It is a pleasure to review products and brands, where quality and the importance of customer satisfaction are high on the list. Each Fish Finder mentioned is a great deal for under $500, and I could honestly recommend each one to you. Each angler usually has his/her own opinion, and in many cases, it comes down to preference, type of fishing, and type of species being targeted.
However, if I look at the evidence in front of me, the title of “Best Fish Finder under $500” has to go to the outstanding Lowrance Reveal 7 x SplitShot. There is so much technology packed into this unit, it’s a steal at less than 500 bucks. It’s also not just the amount, but the quality and innovation of the technology that really impresses me. With FishReveal, the saving of Sonar readings, C-Map Insight Pro, and Genesis Live Onboard Mapping Function, I feel this model will be competing in the market for quite some time.
There are disadvantages like not having Wi-Fi and not being able to share points, but in all honesty, this is a small price to pay for such a complete package. At the same time, these exclusions make the Fish Finder appealing to anglers with all kinds of budgets.
Technology aside, another great feature of this Fish Finder is the quality and durability. These are extremely important features to consider when looking to purchase, and Lowrance has been focused on this aspect since they started manufacturing way back in the 1960s. Each unit undergoes extensive quality control which results in an impressive five-year warranty.
