Finding The Best Fish Finder Under 500 Dollars | A Definitive Buyer’s Guide

There are fish finders out there that will cost more than your trailer, motor, and boat combined. Don’t go overboard here. Know your needs first before you decide on a model for your next fishing trip.

Sonar

The first requirement is 2d or traditional sonar. When you think about it, it’s not really a requirement since all the fish finders out there have this function. 2D sonar is great for determining the size of the object or fish directly below your boat, thanks to its color palette.

It will depend on the kind of color palette you have. A darker color tone flashing on the screen will indicate that there are bigger fish right below your boat. It can also mean bigger pieces of structure.

This is something you will get the hang of after countless trials and errors. Pretty much on all fish finder units, traditional sonar is a universal feature. However, this alone won’t do a good job of finding fish. This is where down imaging and side imaging comes into play.

Down Imaging

The second thing is down imaging, down scan, or down view, whatever you want to call it. These are called different things, depending on the manufacturer. For example, Lowrance calls it down scan, Humminbird calls it down imaging, and Garmin uses down view.

While the name may differ, they all do the same thing, which is to look directly below your boat. The sonar cone is a little bit wider than your regular 2D sonar.

But what makes this down imaging shine is the separation between fish and a brush pile or fish in the bottom. This separation is a lot clearer compared to your traditional or 2D sonar.

If you fish a lot of brush piles or you fish a lot of rocks or maybe fish that are on the bottom like walleye or catfish or something that are fairly consistently on the bottom, that separation between the actual lake bottom or river bottom becomes very clear with down imaging.

Side Imaging

Last but certainly not least, I would highly recommend you save up. If you don’t have the 500 saved up yet, you save up to that mark specifically for a more advanced feature, and that is side imaging sonar.

This side imaging sonar is the key when trying to make the most of your fishing and being out of the water. This feature becomes really useful, especially if you are on a new body of water.

Side imaging allows you to be very efficient when finding fish or structure. You can scan left and right, and both depending on the manufacturer. The coverage is about 100 to 150 feet left and right of the boat.

You can even find weed edges, brush piles, trees, rock piles, and also schools of fish. There is a slight learning curve to it, but it is worth learning. Side imaging is the key with these units. And that’s why I highly recommend you save up to this 500-dollar mark to get that side imaging feature.

GPS Mapping Technology

What really separates out the units that I have listed here is the GPS mapping technology. Some of these fish finders have preloaded maps, and some of them feature SD card slots.

You can upload new maps depending on the region that you are fishing. This is what is really going to separate the best ones from the rest. Some of the units can take both the Navionics mapping card and the LakeMaster mapping card.

For those who don’t know what those are, Navionics is a popular company that produces mapping contour chips. You can upload your own maps to the units that support these contour chips.

LakeMaster is a separate company that produces similar topographic maps and contour maps for lakes. Now the difference is, in some areas of the country, Navionics is much better in terms of contour lines being relative to what you actually see on your lake river.

In some parts of the country, LakeMaster shines when it comes to the accuracy of contours and depths. So, depending on where you live and the local lakes that you fish, you want to do your research first.

Navionics & LakeMaster have their own list based on region. You can actually look those up. Just go to their official website. The best depth finder unit is the one that can accept or feature both of these.

Portable Options

Let’s say you have a smaller watercraft, kayak, canoe, or sometimes those inflatable pontoons; you can buy a portable fish finder. These models usually come with a battery as well as a recharging system.

These portable models are also great for ice fishing as well. Speaking of ice fishing, go with an ice fishing bundle to get the most value for your money.

Also, there are models with GPS mapping units. However, those are only a base mapping unit. You will only get the outline of the body of water, but unfortunately, they won’t provide a topographic map or contour map detailing the lake bottom.

You also can’t really get an upgrade for those models, so keep that in mind when you are really going down the budget route. If GPS mapping systems aren’t that important to you, you can definitely go with those smaller, portable units.

User Friendliness

Garmin and Lowrance units are what a lot of people would argue are the most user-friendly units on the market. They are fairly basic. There are some units that are more advanced in terms of manual settings.

If you are brand new to fishing sonar and you don’t have any idea how to adjust the sonar, go with a model that features Autotuning sonar. The Lowrance Hook series of fish finders is a prime example of what I’m talking about.

Once you get into the kind of advance settings, and you know how to use these sonars and tweak them in terms of manual settings, then those beginner-friendly units might actually bother you a little bit.

The Humminbird units are fairly manual user friendly and give you a lot of options to tweak and customize the sonar.

Display

A larger display is always better. If you are mounting your fishfinder on the bow of your boat, or it is at a distance from where you are sitting, maybe it is at your helm, then a 7-inch display might be a requirement for you.

If you don’t care about a large display, then any sonar unit with a solid performance will be a good option for you. You can downsize a bit and go with a 5-inch display to save a couple of bucks if you are on a tight budget.

Frequently Asked Questions

1. What to expect from a fish finder under 500 dollars?

At this price point, you can enjoy some of the features that the top of the line models has. While you can’t expect to have them all, however, the basic must-have features are there. For example, CHIRP is pretty standard in these models.

You can also expect side imaging and down imaging functions to be present, as well as GPS mapping technology.

2. What are the most popular fishfinder brands out there at this price range?

Under 500 dollars, you can get your hands on some of the most popular and leading fish finder brands on the market. For example, Garmin, Humminbird, Lowrance, Deeper have units in this price range.

Over the years, fish finders have become very accurate, and you can now get different types of them depending on how you plan on fishing.

3. Are depth finders’ waterproof?

The main unit, which is the control box, and the display are not waterproof. However, the parts that go below the water certainly are. You should always keep your device away from water. Try using a case to protect it. The castable units on the hand are completely waterproof.

4. Can you see water temperature on a fish finder?

Yes. Some of the depth finders allow you to check the water temperature. Within the transducer, there is a temperature gauge. It comes standard, and the majority of the fish finders have this unit built in.

It’s important to know the water temp. Judging by the water temperature, you can easily determine the type of fish that are in that location.

Final Thoughts

The HELIX 7 from Humminbird is arguably the best bang for your buck under 500 dollars for a lot of reasons. It has 2D sonar, the down imaging, and side imaging, and its ability to take a Navionics map card and a LakeMaster’s mapping card.

Considering all that, there are hardly any units that can rival this model at this price range. Finding the best fish finder under 500 dollars isn’t that hard because this is the sweet spot of these sonar units. You can get small devices that are packed with features.
