Humminbird Piranhamax 4 Di Features

Its display or screen

Humminbird piranhamax 4 di screen display

Piranhamax 4 di has a 4.3 color display screen with a pixel matrix of 480 by 272. It also has a LED backlight which allows you to use it any time regardless of the weather condition. Since it doesn’t have a touchscreen, you’ll have to control the display using the buttons. It also doesn’t include the split-screen feature, which doesn’t allow you to read different data simultaneously.

However, if you want to change the display of this device, you can make good use of the zoom function and read the screen with ease. You can also make good use of the contrast feature in the hummingbird 4 di settings and set a clearer distinction between the lighter and darker parts of the sonar. Alternatively, you can use the Whiteline function setup that helps in replacing one of the colors with white, resulting in stark contrast.

Having an IPX7 waterproof can withstand rain, water splashes, and you can immerse it 3.3 feet underwater for 30 minutes. But ensure you protect it against dirt and dust for it to last longer.

Sonar and transducer

This device consists of an XNT9 DI T transducer that has a transom mount. It also contains a temperature sensor. It includes both 2D and down imaging sonars.

You’ll see 18 degrees wide,455kHz cone for clear bottom imaging with the dual-beam sonar while 28 degrees wide 200kHz cone. Although it doesn’t give better coverage, it helps you scan images underwater like structures and fish. Remember this device allows you to use one beam at ago.

The Di sonar uses a thinner, wider angled beam of 75 degrees for 455, and it’s the only channel. It includes a 2.5″ target separation, although with no chirp technology. This sonar is best for looking at underwater structures while also differentiating between fish and vegetation. Hitting 50kHz with this small device is never easy since it has limited reach.

The maximum depth of this device is 320 feet for Di, and the 2D is 600 feet. But you can get accurate readings at around 30MPH, although its manufacturer suggests a speed of between 1 and 6MPH for better results.


Since this device doesn’t have NMEA ports, microSD card slots, and ethernet capabilities, it can’t connect with other devices. This means that this unit doesn’t offer any traditional options.

The alarm features

One reason you opt for a fish finder while out in the water is to maximize your catch. However, not every day is agood day in water since you can spend hours looking for fish in vain. After such frustrations, you may lose focus and attention and miss seeing some passing fish in the long run. But with Humminbird piranhamax 4 di setup that consists of three alarms, you can redeem yourself. The fish alarm will ring when the Humminbird piranhamax 4 di transducer identifies a fish. To hear this alarm sound ensure you set it at a preferred volume so that it doesn’t ring unnoticed.

This device also has a depth alarm which helps you know when your vessel hits a certain depth. The last alarm on this unit which you can set at will, is the battery alarm. It sounds when your fish finder’s power is below the recommended percentage.

The advantage of selecting this device apart from its affordability is that it comes with a transducer not to buy it separately. Its also easy to use, read and install, making it the best choice of fish finder with down imaging technology. You can check the latest price here on Amazon!
