scanner

Looking for Raymarine Open Array Scanner. Doesn't have to be HD, hoping to spend less than what a new one would go for. I don't mind if it's a few years old, as long as it turns! Thanks!

Hi guys. The part shown is attached to a Raymarine open array scanner (left side). The right cap is missing. I'd like to find a replacement so please PM me if you have any spare parts or know anyone who does.
