Humminbird Piranhamax 197c DI Review & Features

Now we will explore the features and reviews the Humminbird Piranhamax 197c device. Firstly we begin with the transducer performance. Then will move towards the screen and other features of this product. So without a further delay let’s begin.

The Transducer

The specs of this fish finder are quite basic so does its price. Its echo sounding transducer has a dual beam frequency that operates at 200 kHz and 455 kHz. This means that it can scan water at narrow and wire frequencies. This will lead to better rendering of the underwater geography. You can easily differentiate between rocks, plants, seabed and fishes. By the help of 200 kHz scanning frequency it can scan water at 320 feet (97 meters) deep. And using its 455 kHz scanning mode it can go as deep as 600 feet (183 meters). This depth range is quite okay for most of the fisherman. If you go for small lakes and rivers for fishing this will be more than sufficient.

Transducer Output Power

The transducer of Humminbird piranhamax 197c DI can give 200W power output. And for peak-to-peak it deliver up- to 1600W. More than enough for casual angler today. All in all I am satisfied with its sounder power ratings. Although average power output is 300W RMS


Since this is a portable fish finder it has small display to keep the product size compact. It has 3.5 inch coloured screen with 320 x 240 pixel resolution. This resolution seem to lower side of many fish finders but it is actually crisp and clear in real. Being small size display the resolution is perfect that feel. Also it has 256 shades of color for superior images.

In this humminbird piranhamax 197c DI review, I personally like this 256 color screen. The reason is it is easy to read when compared to full color fish finder. The display is LED backlit and works in every lighting conditions. In direct sunlight it does not looses it details. This is why I prefer this display. Yes the 3.5-inch size may look small sometime. To keep the device portable it should not be more than this. And we can mount this device close to us for easy readings. This way the smaller screen size will also doesn’t matter.
