PiranhaMAX 4 Di Review

The display of the Piranhamax 4 DI is a 4.3-inch 256 color TFT display. The unit comes with an LED backlight that makes it possible to use the unit during the daytime or nighttime. The screen is also polarized and has an adjustable viewing angle so you can customize your view.

There is no touchscreen on the unit, but all of the buttons you need to control the unit are located on the front of the display. And it does not feature any split-screen function.

Sonar & Transducer:

The Piranhamax 4 DI uses a dual beam sonar with two beams: a wide beam and a narrow beam. The wide beam gives you a generous coverage area that is perfect for finding fish, while the narrow beam provides great detail when targeting structure and contours beneath the waterline.

The sonar device is a marvel of technological innovation. It has two beams, which are each made up 200kHz and 455 kHz frequency sounds with conical angles at 28° or 16 ° respectively- this allows for exceptional coverage when scanning underwater structures but it can only use one beam at a time!

The Di sonar is a specialized device for identifying underwater structures and differentiating between vegetation. It features the CHIRP tech, which enables it to produce very thin beams that can go deeper into the water than other models with similar size or power output without producing excess noise interference from high-frequency signals like LOAs (Low-Oscillation Frequency).

With 2.5-inch target separation rates on both 455 kHz channels combined; there are plenty of opportunities when fishing around 50kHz but not if you’re using PiranhaMAX 4 dl because its narrow beam angle of 75 degrees won’t allow them in – limiting reach even further while still being effective at what they do that is essential for small, tight spots.

The transducer also includes a built-in temperature sensor that displays the water’s temperature on the display. This is a helpful feature if you are trying to determine what type of fish you are catching.


The DI has a tilt and swivel mount that lets you quickly adjust the viewing area angle. This is perfect for when you want to view the sonar from different angles or positions on your boat.

Down Imaging (DI):

The unit also uses Down Imaging technology, which gives you a clear view of what’s happening below the water surface. This is a great feature for seeing fish and identifying structures in murky water.


The Humminbird’s new PiranhaMAX 4 Di does not offer any traditional connectivity options. In other words, it lacks NMEA ports and Ethernet capabilities or microSD card readers which are common features in many sonars today.

I was really disappointed when I found out that the newest Piranhas from Humminbird don’t come with either of those two things-a network connection so you can get data remotely via your phone app as some higher-end models do.


The PIRANHA MAX 4 DI weighs just 2.0 lbs and its compact size makes it perfect for portability. It also comes with a swivel power cord, so you can use the sonar in different areas of your boat without having to unplug everything.


The Humminbird Piranhamax 4 DI is built with a tilt and swivel mount that lets you quickly adjust your viewing angle to whatever you need it to be, making it easier to use in a wider variety of boats.

It also uses an all-weather design that is resistant to sun, rain, and snow so you can take it with you wherever you go.

The Humminbird Piranhamax 4 DI also features a portable design that is lightweight and easy to install on any kayak or boat.

What You Will Get:

You will get inside the box: 1 Humminbird Piranhax 4 DI, an XNT 9 di T transducer, and even more! You’ll also receive an excellent tilt-and swivel mount that can accommodate any type of sportfishing or shallow water Kayak.

The best part about all this? The low price for high-quality fishing equipment delivered straight to your door doorstep – just like magic!!

Final Verdict:

The Humminbird Piranhamax 4 DI is a great choice for anglers who want an affordable, easy-to-use fishfinder with Down Imaging technology. This unit is perfect for kayaks and smaller boats, and it’s portable enough to take with you wherever you go.

So, if you’re looking for a new fish finder that will help you take your fishing game to the next level, the Humminbird Piranhamax 4 DI is worth checking out!
