Humminbird Piranhamax 4 Review

Humminbird piranhamax 4 with its advanced features, 4.3” color LCD and an easy-to-use interface can provide you with the best-quality fishing experience ever. The PiranhaMAX 4 is one of the latest models of the P-MAX series from Humminbird. 

It is a self-operated fish finder that does not have any navigation features, such as GPS or charts. It doesn’t use CHIRP technology, but still, offers clear imaging for depths up to 600ft.

Features of the best Humminbird fish finder that cannot be missed

Easy-to-use tilt and swivel mount 

This model is furnished with a twirl and swivel mount with an additional option of a dash-mourning kit. This product does not contain a unit cover. The head unit’s plastic frame is an extremely tough plastic frame and features a one-panel view (no split-screen). It runs on a 12v 5-7-amp battery.

Unique triple Alarm System 

This is the best portable fish finder that is equipped with a triple alarm system: Fish Alarm, Battery Alarm and Depth alarm. The Fish Alarm will emit sound when the target beam hits a target which it interprets as fish. 

There are three-fish size alternatives for this alarm, i.e. ‘Large, Medium and small” and you can select any of these options or even all so that the alarm will produce sound when it traces a fish, corresponding to the customized setting.

To use the Depth Alarm, you have to select a particular depth value and when the beam reaches a depth lower or equal to it, it will create a noise and finally, the Battery Alarm will give you an alert when the battery drops below a definite voltage. Hence this stands out among the best fish finder with maps that are highly customized for its users so that even a beginner can spot and catch fishes like a pro.

Stunning display and interface

This model offers a vibrant display with a 12% increase in screen size, paired with 70% more pixel than its previous versions, with a 480Vx272H pixel resolution and a 4.3 inch color TFT. 

It also has a vivid 256 color range so that you can create a more sharp contrast between the colors in order to have a more clear distinction between the light and dark parts of the sonar. It also comes with a LED backlight which means you will absolutely face no problems to get a clear visibility of the readings be it a bright sunny day or a fog-covered night.

Fish ID+ Function along with a transducer with a temperature sensor

The Fish ID+ function basically interprets the fish arches (or maybe other obstacles which are detected as fish) with small fish icons. This feature is a great useful tool if you are not habituated with the raw sonar view. Structure ID is a function that represents the weak sonar returns as light pixels, and other strong returns as dark pixels. 

Whiteline shows the sonar returns in white with the highest strength, which helps to give a more focused sharp view of the bottom, with the help of bottom view function. The XNT 9 28 T, Transducer model is integrated with a temperature sensor, which can indicate the temperature in the top layers of water. It is equipped with a 20 ft. cable and is capable of detecting water currents.

Key Feature that make the Humminbird Piranhamax 4 stand apart

Smart Dual Beam Sonar

The basic foundation of the best kayak fish finder is determined by the quality of the sonar. So, let us understand here how a sonar works. The finder automatically will figure out the depth and emit sound waves from the transducer that penetrates into the water and again sends out sound waves in the reverse direction.

When these sound waves collide against an object they tend to bounce back and you get your sonar reading. The specialty of this dual-beam sonar is that you will get a 16 degree wide, 445 kHz cone for a crystal clear image of the bottom of the sea and different-coloured lines will determine how strong your returning sonar waves are (blue=weak, yellow=medium; red=strong) and even different fish icons will determine the size of the fish so that you can decide for yourself the size of fishes you want to fish.
