The Best Fish Finder GPS Combos Under $500 in 2020 Review And Guide

A GPS fish finder combination would be a welcome addition to any angler’s gear range. When these handy tools are used correctly, you can ensure that each and every minute you spend on the water is put to good use.

Beyond just a pole and a string, the next piece of equipment that I can suggest to anglers looking to take their fishing to the next level is a decent fish finder GPS combo.

They can be great tools not only to maximize your fishing hits but also to train fishermen and expand their understanding of fish behavior as it makes us able to Chart Fishing Hot Spots, GPS Plotting of Bottom Structure, Waypoint Saving because of it 3D Imaging of Bottom Topography.

Transducer of the gadget transforms the electrical pulses to sound signals from the fish finder. Such waves pass down to the bottom surface or on a fish across the depth of the water, and the return echo that the fish finder transducer picks up, which transforms it into electrical impulses.

Such electrical impulses are those that are sent back to the fish finder where they are transformed into symbols or images. The fish finder which have advanced GPS technology, can display the vessel’s location as it travels on water.

So, in order to help you to buy the high performance and cost effective gadget, here we are listing down our picks of best fish finder GPS combo under 500$.

Garmin Striker 4 with Transducer, 3.5″

The Striker 4 is Garmin’s base fish finder in the Striker line.

A-Scope function allows real-time feedback and you can see fish passing through beam of the transducer. The fish finder uses sophisticated GPS technology which can indicate the vessel’s location as it travels on water.

The monitor is tiny but the color and graphics look pretty good indeed. HVGA isn’t particularly impressive by the standards of today, but you pay more for the stuff behind the computer. And, that is fine.

This cost-friendly tool has a pretty decent temperature sensor feature and logging. That as any angler knows is one of the most critical bits of data available to you. 

If you know fish finders or other software, you should have zero problems. When you fail to set up a telephone or email account, however, there may be some learning curve there. Still, nothing too bad.

This is the Garmin thing. They have vast experience in creating apps user friendly and responsive.

Dual-frequency (50/200 khz) sonar capable
Dual-beam (77/200 khz) sonar capable
Frequencies supported: Traditional: 50/77/200 khz
Chirp (mid and high)
Transmit power: 200 w (rms)
Maximum depth: 1,600 ft freshwater, 750 ft saltwater

  • High-sensitivity GPS
  • CHIRP sonar transducer
  • Fish Symbol ID
  • Adjustable depth line measures
  • Low pixel count

Final Verdict:

The Garmin Striker 4 is a simple device, very basic. And, this means you don’t have many menu items and apps to work through.

Garmin Striker 4 with Portable Kit

This fish finder can also provide navigational services with its built-in GPS, in addition to helping you track fish. Enabled with these GPS tools, you get access to a high-sensitivity mapping that helps to easily and precisely locate your current location, with the ability to map and save locations where you know fish are also.
Also critical places such as boat ramps, docks, and hurdles can be marked and saved, and shared with other anglers who also use Strikers.
In the package, you can save up to 5000 way points, which is probably more than you’d ever need. This fish finder has a sleek style that is both elegant and user-friendly.
It’s portable and ideal for smaller boat use. The keyboards are large enough to command you even though you wear gloves and are very responsive, too.

Tips to buy:

Fishfinder is a vital part of any angler ‘s arsenal and a large range is available. To simplify this phase we will look at five attributes of the GPS combination of fishfinder to figure out which one is the right one for you.

Combo or Stand Alone:
The first question you should ask is if you want your fish finder to be combined with or without a GPS map plotter?
It is very useful to have GPS navigation, especially on a smaller boat when combining these two functions on one display.

Screen Size:
The second question you want to know is how large a screen is? It is much bigger, because you obviously have to increase the budget if you want to have a bigger screen. The dimensions of the screen range from a 3.5-inch small to a 7-inch or even larger monitor.

This is a very important attribute. The power of such equipment is expressed in RMS watts. The smaller fish finders can have as little as 100 RMS watts whereas the bigger ones can have as much as a thousand watts.

There are several models that give a difference in frequency or so. Things like 50 or 200 kHz. They’ll have something. In shallow water, higher frequencies are generally better, and lower frequencies perform well.


Choosing a best fish finder under $500 transducer can be a bit tough, especially if you have not done it before, but, if you even slightly brief yourself with what a good transducer must have then you will not have any issue. Therefore, remember that a good transducer must have stable and sturdy mounting plus it must have good beam width as well as frequency because it will determine how well the signal will bounce.


Is chirp better than sonar?

A conventional sonar transmits about 1% of the time, but CHIRP sonars transmit ascending pulses, which are 10 times longer. They are adding significantly more energy, ten- to fifty times more than traditional fishfinders, although CHIRP devices frequently transmit less energy at the peak.

Is side imaging better than down imaging?

Fish founders with a transducer showing down sonar waves under your boat, while fish finders with a side picture are aiming their beams toward your boat’s sides. Both forms are inherently better than others, and both can help you find more fish (and thus catch).

Is Garmin better than Lowrance?

In the low price range, Lowrance has several more options. The cheaper versions also have premium features that popularize them with anyone interested in pricing. Garmn provides excellent price in the center of the country but they are much expensive.
