MyFishFinder.com Just like iceshanty but warmer
can only say that lowrance x67ice is a great little machine
I have used both the LX5 and the FL20, but I cant speak for the H-bird. I would recommend the FL20 over the LX5. Im currently a Marcum LX7 user, and Im super happy, but I would not take the lower level Marcums over a Vex (personal opinion)
