This unit has been on my boat since the end of last year. It looks and functions like new. Always kept inside when not in use. It currently has 208 hrs on it. I currently have it linked via Ethernet hub to an equally mint condition Humminbird 998 that is also for sale in a different post. I'm asking $1500 OBO. I prefer a local sale. Everything that came with the unit is included. Even the box.
Good question. I spend my time on Athens, Tyler, and Jacksonville. Rarely do I fish more than four hours at a time about once or twice per week. And that's not every week. I wish I could be more specific. Both of these units are truly like new. No issues whatsoever. Ever.
