If you see it at the 12 mark, that means bottom is around 12 feet down. Bottom will usually pop up as a long red line. We can adjust depth and we’ll talk about that later in the “Features” section. The numbers range from 1 to 20 and indicate how many feet down things are. You’ll see numbers along the perimeter of the flasher and those numbers will tell you how deep down objects are appearing. The color scheme is as straightforward as possible: green signals are weak, yellow signals are of medium strength, and red signals are strong. This flat screen is incredibly handy when you’ve got a lot of buddies fishing with you because it can be viewed from a variety of different angles. You’ve got a flat screen and bright LEDs. The display on the FLX-12 is the pinnacle of simplicity if you’ve used a flasher before, you probably know exactly how this thing works.
