The Vexilar FLX-12 Pro Pack II with 12 Degree Ice Ducer offers a flat-screen design with brushless data transfer technology. The LEDs deliver a 20% brighter and sharper display. This unit has a special low power mode option that allows you to fish in extremely shallow water with great target resolution. This unit offers five depth ranges to 120 feet. It also offers a unique night mode option so the display is easier to view at night and also lights up the center depth graphics. There are 20 steps of Interference rejection (IR) to help knock-out interference from other sonar systems. If your battery is running low, the display gives a coded series of flashes long before the unit shuts down. When you put the FLX-12 using Vexilar’s Brushless data transfer technology, you get a sunlight readable display with a built in low power mode and ranges to 120 feet. This pack is ready for the ice right out of the package with a 12 degree Ice Ducer transducer.
