Humminbird G3N MSI. All season ,317 hours. Works good. Shuttle and 20ah battery. Comes with every thing seen plus the SI transducer and transom quick mount ( thats in my stored camper until 4-14) Only thing not included is the charger $35 from Amazon. No lake map included. I made this portable to fish with a buddys boat. Battery will run all day. This unit is 360 compatible on network. The screen still has the factory plastic on it for protection. $700obo
