RE: Vex or Marcum?
I have a Lowrance. X-67 Ice machine. Love it. Only complaint I have is the transducer arm that comes on the X-67. It works, but I like the floating transducer holder that comes with the Vex. Could probably rig something up for mine, just havn't bothered yet. I think Vex, Marcum, and Lowrance are all good units.
