Humminbird PiranhaMAX 197c Using precision sonar, the Humminbird PiranhaMax 197c DI makes aquatic environments as clear as day. The fish will never rest easy again. A compact device measuring roughly 5.6 by 3.9 inches on the front and just over 1.3 inches deep, the new PiranhaMax features a 3.5-inch LCD monitor with 320 by 240 pixel resolution. Combined with 256 hues of color, the LED-backlit screen supplies an especially detailed picture to show just where the fish are biting. To make the device easier to operate under all circumstances, a gimbal mount is provided that allows the unit to be rotated and tilted. It can also be in-dash mounted. Using 10 to 20 volts DC with 220 mA supplied by the boat, the unit generates an average of 300 watts of energy that reaches a peak-to-peak output of 1,600 watts.
