When you’re out on the open seas and truly in the thick of it, you may find yourself wondering what the heck you’re doing waiting around for a fish to take a bite. It can be grueling, if not a waste of your Sunday, floating around with all the other boats, waiting for some kind of miraculous catch.
Though fish finders have been around since the '90s, the technology is always changing and improving, so the old school one your dad used on fishing trips back in the day doesn’t even compare to the ones on the market today. That being said, not all fish finders are equal.
Read on to learn about some pros and cons to look out for when you’re choosing the right fish finder for you.

Pros and Cons of Using a Fish Finder with GPS
If you’ve ever been out on a boat in the middle of nowhere, you know how difficult it can be to pinpoint where you are, unless you have a GPS. Knowing where you are in relation to land is not only the safest way to be out on a boat, but it makes fishing much more productive and efficient.
Opting for a fish finder with GPS allows you to not only find the areas with the best fishing, but gives you the ability to record that area and return to it next season or many fishing seasons in the future. This will allow you to speed up your fishing and come home with something you, and your family, will be super impressed with.
While you could choose to go with a fish finder and a separate GPS, this creates a lot of clutter where you really don’t need it: on your boat. By having a fish finder and a GPS in one unit you’ll save yourself money and streamline your whole experience.
The only real downfall of fish finder/GPS combos is their price. As compared to a standalone fish finder unit, a GPS combo option can cost you about twice as much. However, when you consider the price of buying two separate units, you can save yourself some money in the long run.
What Makes a Good GPS Fish Finder?
When you’re on the lookout for a quality GPS fish finder, there are a few distinguishing details to look out for.
CHIRP vs. Side Scanner vs. Down Scanner
While we don’t have to get into the nitty-gritty of sonar technology, you’ll want to consider how you want your fish finder to, well, find fish. Down imaging and side imaging essentially refers to the direction in which the sonar is transmitting waves.
Down imaging will track below your boat, while side imaging will track out to the side of your boat. Keep in mind that many companies have different terms for down and side scanning, so it may be difficult to know exactly what they’re talking about. Don’t worry, we will clarify it all in the reviews later on.
CHIRP is a sonar technology that provides you with an even clearer image of what’s going on around your boat. If you’re doing any kind of deep-sea fishing, this may be a detail to consider.
Screen Size and Quality
First off, consider the screen quality and size. You’ll want to look out for a screen with a color display and decent resolution. While you aren’t watching the Super Bowl, and won’t need an HD screen, a decent screen resolution can make a difference between catching that fish and letting it swim off.
As for screen size, this is really personal preference. Oftentimes you can find a fish finder in a 3”, 5”, or 7” screen, and the decision on which size to purchase will be based off how much you want (or need) to squint. If your sight has turned against you in your older years, a 7” screen might be a worthwhile investment.
Depending on where you’re fishing and how far inland you are, you’ll want to consider how deep the fish finder can track. While how deep the GPS tracks isn’t necessarily an indicator of quality, it does make a difference based on how and where you’re fishing.
