Looks like Hummingbird is going to have a live unit early next year. If it does not have the ghost tree and/or Garmin does not fix their ghost tree issue then they will loose customers. Mostly new ones I would think. I have gotten use to it when water conditions change and it shows up more pronounced than at other times. So it would not get me to drop another $3500 just to get rid of it. But there are a lot of people that would. If I was upgrading my system I would buy it instead of Garmin. That's if Hummingbird has solved the ghost tree problem. They might have because their system does not require a "black box".
