Been fishing vex's for close to 20 years. Picked up a FL-22 HD last season and only got to use it around 6 times. Not a bad unit but heavy. I used a Lowrance M-68C more last season and really like it more than my vex. Has GPS built into it with the maps already. Great for going back to the same spots that produced for me. Dont overlook the new Lowrance icefishing units. Should have included them in your poll.
