I have one and love it. I built my own platform for it so that I can easily take it on and off my machine when I'm using the gps. I never use the flasher setting, only the graph and I have zero problems marking my jigs/fish. If you keep the brightness on level 10 it does eat up the battery. I keep mine on 6 inside the shanty and it lasts all day. I keep seeing more guys out on the ice with them this year.
