Hey Cane Pole

I'm looking for a sonar unit to go with a Terrova with US2, either Humminbird 570,718 or 728. What are your thoughts? gary

HB makes good units. I looked up the specs. If these were my only choices, I personally would pick the 728. I base this pick on power (500w rms) and pixel count (640 x 320). All other specs seem similar.

The only thing I don't like about the small units is the disconnect. I kept my 797 mount hosed down with wd40. This helps.

Hey Cane Pole Do any or all these units show temp. with only the US2 on the troller? Thanks a lot gary

Based on the specs, all should be capable based on the fact that they can read the specified transducer that comes with the unit.
