Screen Resolution:

The power of a finder determines its strength. It determines how well the angler will be able to see objects in silt-laden water. Also, the peak-to-peak power plays a critical role in showing the strength of the device. It helps to resolve, separate the bottom structure and the targets.

Note that the greater the wattage, the faster the finder will be able to display the readings and the lesser the wattage, the slower the unit will display the reading. More power allows the transducer to send waves to the objects which bounce back and allow the images to be displayed on the screen.
