The unit was working fine when it was removed from my boat. It comes with the head unit plus one transom transducer. I'm throwing in the speed wheel option as well since I don't need it with my new unit.
The speed wheel mounting bracket is cracked but can be fixed easily with super glue. The pin may be slightly bent as well. It wont spin freely if shifted to one side.
You can find the specs here:
