The Humminbird Piranhamax 4 and Garmin Striker 4 fish finders are popular entry level models from two of the best companies currently producing fishing electronics. They retail at an almost identical price point just above $100, and are both designed to provide basic fish finder capabilities at an affordable price.

So what are their differences, and which one is better value for money?

In this article we compare the Piranhamax 4 with the Striker 4 side by side, and discuss their pros and cons in detail, so you can decide which one is best for your purposes.

In the table above we compare the most important specifications and features of the two fish finder models.

As you can see, they are broadly similar, but there are significant differences when you dive into the details.

Let’s look at the main differences between the two models  in more detail.

The most important differences between the Humminbird Piranhamax 4 and Garmin Striker 4

Display size: With 4.3” diagonal, the Piranhamax 4 has a larger screen than the Stiker 4, which has a 3.5” diagonal. If screen size is important to you, then this point definitely goes to the Humminbird model.

Bottom line: The Piranhamax 4 has a more generous screen size, which makes it easier to read the screen.

Screen resolution: The Striker 4 has a slightly better resolution, with 300 x 480 pixels, compared to 272 x 480 pixels. However, this difference is hardly noticeable, and shouldn’t make a difference in most cases.

Split screen functionality: While the Striker unit has a split screen functionality, the Piranhamax unit does not. This makes a big difference, since you can use the split screen on the Striker to look at GPS waypoints and sonar signals at the same time, or to zoom in one part of the screen, while looking at the bigger picture on the other part. As fish finders have become more and more sophisticated over the past decade or so, split screen functionality helps a lot to take full advantage of all their features at the same time.

Bottom line: The Striker 4 has split screen functionality, which is extremely useful to make use of several features side by side, while the Piranhamax 4 does not.

Dual beam sonar: Both units are identical in this regard, and come with dual beam sonar. Essentially, this means the transducer sends out two pulses at the same time, one narrow and focused, and one broader with less detail.

Sonar frequencies: This is another category with big differences between the two units. The Piranhamax comes with 200 & 455 kHz, while the Striker comes with 50, 77 & 200 kHz. 200 kHz is ideal for freshwater fishing in rivers and lakes. The lower frequencies are useful for fishing in deeper water, and so come in handy for inshore fishing. 

Bottom line: Both units have 200 kHz sonar, which is ideal for most freshwater fishing applications. In addition, the Striker 4 has 50 and 77 kHz sonar, which is useful for fishing in deeper inshore waters.

CHIRP sonar: The Striker 4 comes with a Garmin CHIRP transducer, which improves signal resolution and results in a higher level of detail and clarity. In contrast, the Piranhamax 4 only has regular sonar.

Bottom line: The Striker 4 provides higher quality sonar performance due to its CHIRP technology.

Maximum depth: The Striker 4 has a significantly greater depth of 1,600 feet, compared to the 600 feet of the Piranhamax 4. This is due to the lower frequency wavelengths, which penetrate better into deeper water. 

Fish ID technology: Both models are identical in this regard. With Fish ID you can essentially let the fish finder decide which signals are fish, and label them as such on your screen, which is a great feature for beginners.

Temperature sensor: Both units are identical in this regard, and come with a transducer with a temperature sensor.

Speed sensor: While the Striker 4 measures speed, the Piranhamax 4 does not. This feature is especially useful for trolling, if you want to make sure you’re trolling at the correct speed.

GPS: This is another area with a major difference. While the Striker 4 has a GPS receiver that you can use for navigation, as well as placing waypoints, the Piranhamax 4 does not. This is a big deal, since placing waypoints allows you to find your way back to specific locations quickly and easily.

Bottom line: The Striker 4 has a GPS receiver that can be used for navigation and for placing waypoints, while the Piranhamax does not.

Now let’s look at each of the two units in more detail.

 

Humminbird Piranhamax 4

This is the most affordable Humminbird entry level fish finder. It’s designed to provide the most basic sonar capabilities without any bells and whistles. One of its best features is the generous 4.3” display, which allows you to see details more easily. In addition to Fish-ID technology, it also has several alarm features that can be very useful. For example, you can set an alarm for when it detects fish, or a change in depth.

Features:

  • 4.4” color TFT display
  • Transom mounted transducer
  • 2.5” target separation

 

Garmin Striker 4

This unit has consistently been the most popular entry level fish finder for many years, and continues to outperform other models in its category. Not only does it pack surprisingly powerful sonar capabilities that can handle a maximum water depth of up 1600 feet, it also comes with CHIRP sonar, which was unheard of in the 100 dollar fish finder class until recently. 

If you add to this the GPS functionality with waypoint mapping, and combine it with the split screen functionality of this Striker 4, this unit provides highly impressive mapping and sonar functionalities that are not usually found in this price category.

Features:

  • CHIRP transducer
  • GPS functionality with waypoint mapping
  • Speed sensor
  • Built-in flasher functionality

 

Conclusion

While both models reviewed here are high quality entry level fish finders, the Garmin Striker 4 wins the contest, as it provides both higher quality sonar imaging (with its CHIRP transducer), as well as powerful additional features that are lacking in the Piranhamax 4.

These features include: GPS with waypoint mapping, split screen functionality, and speed measurement. In our opinion, this makes it the best $100 fish finder currently on the market.
