I have a new, unopened, not used, not damaged Humminbird 385ci Kayak Edition in its original factory packaging. I bought it about a year ago, never installed or even opened it. It's been sitting in the basement all this time and now it looks like I'm not going to need it. I can sell it for $300 or best offer.
You don't have to spend hundreds of dollars when buying a fishfinder. I really like my Piranhamax 195c and looks like I'm not the only that likes this unit: http://www.fishfinders.info/humminbird-piranhamax-195c-review
