Now that we’re done with the pure technicals, let’s get straight to the point.

1. Garmin Striker 4 – Best Overall

Garmin Striker 4

Let’s start with the Garmin Striker 4, as it brings an awe-inspiring package to the competition. Firstly, it comes with a built-in GPS, in addition to CHIRP sonar and transducer, allowing for image-like sonar results and maximum accuracy.

Moreover, the Garmin Striker 4 is as affordable as it’s flexible. It doesn’t cost an obscene amount of money, and it comes with several modes and options to navigate on your fishing trip.

As a matter of fact, you’ll have a flasher, A-scope, and ultra-scroll, which are all rather helpful. Additionally, this device can support up to 5000 waypoints, allowing you to create all of the routes and maps that you desire.

The Garmin Striker 4 also brings an impressive range of frequencies to the game; 77/200 kHz, in addition to a fish ID feature and the split frequency feature.

Furthermore, we’ve got Vu scanning sonar to support the CHIRP one and provide a more expansive view and an IP rating of 7. The Garmin Striker 4 weighs 8.1 oz and has a 1.9 x 2.9-inch display.

Sadly, although the display is a touchscreen, which is impressive, it remains kind of small; hence, it needs a little bit of extra attention.

Pros

  • GPS
  • CHIRP sonar and transducer
  • Durable
  • 5000 waypoints
  • Ultra-scroll
  • IPX7
  • Split-frequency display
  • Vu scanning sonar

Cons

  • Small screen

Final Verdict

In the end, the Garmin Striker 4 is an incredible model that houses significant strength and durability with its frequency ranges, built-in GPS, and CHIRP technologies.

2. Deeper PRO+ Smart Sonar – Runner-Up

Deeper PRO+ Smart Sonar

Next, we’ve got the Deeper PRO+ Smart Sonar, which is pretty revolutionary when compared with the rest of the models present on the market today.

As suggested by the name, it’s more of a smart version as it comes with a smart sonar that is connected via Wi-Fi directly to your smartphone.

As it doesn’t have a display, everything is broadcasted directly to the much more prominent and more manageable display. Moreover, this fish finder is designed with a dual-band sonar transducer, which doesn’t only carry over the depth of the water and what is in it; but the water’s temperature as well.

Something really convenient about the Deeper PRO+ Smart Sonar is that it has an automatic Wi-Fi connection switch. The moment it hits the water, Wi-Fi is connected, and you’re in your element.

Additionally, it comes with a built-in GPS and the ability to be recharged via USB. Another attribute of the Deeper PRO+ Smart Sonar is its casting range which can reach 330 feet. Plus, of course, its easy interface makes it friendly to all levels of experience.

The Deeper PRO+ Smart Sonar also comes with a specific calendar that predicts fish trips and alerts you to them so that you’re fully aware of what’s going on around you.

That is in addition to the Bathymetric and the Lakebook, which are both highly convenient.  Last but not least, the different modes are standard, boat, ice-fishing, and GPS.

This allows it to help you with any style of fishing, with no trouble whatsoever. The only con is its weight, which, although not incredibly heavy, can’t be supported by all rods as it needs a robust one.

How to Pick the Best Portable Fish Finder

Now, let’s help and guide you through the process of picking out the most suitable portable fish finder for yourself.

GPS

The very first thing that you need to look at is the GPS and what the fish finder can offer you in terms of location services. That can lead to the sonar and transducer technologies available.

Plus, how many waypoints will this fish finder accept? Can it form its own maps and memorize them all? This can come in incredibly handy when you’re out on the water and you want to make your way back to your start point.

Hence, always make sure that your portable fish finder is fitted with top-notch GPS. They can tell you where you are and take you to where you want to be.

Water resistance

This one goes without saying. When you’re out on the water, you don’t want any device that you would have to fuss about. Everything has to be, to an extent, water-resistant, so that it takes the splashes of water.

Not everything has to be utterly water-resistant so that you can dunk it underwater. Nevertheless, fish finders are designed to be completely safe.

Different modes

You can go about your fishing hobby in so many different ways. You can fish onshore, offshore, you can do jigging. You can even do ice-fishing; the techniques are countless, and that’s why a versatile, flexible fish finder is the best way to go about things.

You want a device that will help you no matter what kind of fishing you choose to do; how can a fishfinder do that? Easy, by activating different modes, such as flasher and a-scope.

Weight

We’re talking about portable fish finders; hence, weight is an essential factor here in deciding whether or not you’ll go with this fish finder. So, we’d advise you to take your time trying out the device in your fishing bag and on your boat or kayak.

That way, you’ll know where the device will go and whether or not it’ll fit.

Frequency

The frequency of the sonar or the transducer determines how you’ll see what’s happening under the water. In other words, with lower frequencies, you’ll be getting a much wider base but with a shorter depth of the water column.

On the other hand, when you go with the higher frequencies, you’ll be going way too deep underwater, but with a much narrower circumference of vision.

Fish finders offer both frequencies and present them to you in a split-screen option, which is available with a bunch of our fish finders so that you’re having the best of both worlds.

Anyway, let’s wrap up by going over some recommendations. Our first will be the Garmin Striker 4, with its split frequency display, CHIRP sonar and transducer, ability to store over 5000 waypoints, and, of course, the various modes that you can activate and deactivate.
