I run a Garmin 240 on my dash, but just recently added a Humminbird Legend 2000 up on the bow. It was a reman from Humminbird direct, and I'll tell you, I really like it! Very easy to use, with dials instead of constantly pushing buttons to change a setting. The unit was $115 delivered. Anyone looking for a unit now should checkout Humminbird's site for closeouts, that have a few different models.
