Sold. Like new helix 10 si and 9 di. Only been used a few times but sold boat and don't need anymore. I have a lakemaster card for both units I will sell with for an additional $50 a piece. Prefer to keep them together but would sell separate. Have the dongle and ethernet cord to link units. Both have covers. $1600.00 obo plus shipping. Also still have original boxes. Plz txt 270-625-3492 don't get on here much.
