I have a Humminbird Helix 7 SI GPS G2N Fish Finder for sale. I have had it for about a year now. Everything works as it should and it is the model that has everything in it. Has side imaging with GPS and can connect to an IPilot trolling motor and follow the conture lines of your fishfinder. Also with it, an upgraded transducer is is part of the package. The upgraded transducer makes it easier to see the image on your side imaging. Its amazing to see whats under the water! Let me know if you have any questions. Setup costs over $1000 new!
