Vexilar FLX-28This is a like new Vexilar FLX-28 with pro pack case, 9ah 12v lead acid battery and charger included. I have had this unit for several years and it's always been a great and reliable unit for me.Options for viewing include the following:- auto zoom 1x and 2x zoom which allow you to zoom in on the bottom really well.- auto zoom range which automatically selects the correct range for whatever depth you are fishing- multiple flasher color selections- Low power mode for fishing shallow- adjustable gain- night mode for low light- frequency adjustment to allow for fishing next to other flashers with a different frequency to avoid interference.I'm sure I'm missing some things as well. Thanks!
