This is one of the cheapest units of the new, 600 series, Hummingbird fish finders with Down Imaging. Although it does not have too many navigational options, the Humminbird 678c HD DI sure covers pretty much everything a fish finder should.
Like most units within the Humminbird 600 series, this one comes with a 5-inch diagonal screen, 640 x 480 pixel resolution. It’s a full color unit, with LED backlit screen, making the readings quite easy during night fishing.
Comes with Dual Beam Plus
