Here is a picture of one of the downriggers. They all have ball cradles with two rod holders. Everything in the picture is what they come with.
They are mounted on quick slide mounting bases. The bottom part of bases are permantly mounted on the boat. If you wish to use the quick slide mounts, you will have to purchase the bases from Big Jon.
I added a ball retrieval cord to each rigger, and they all have a blacks release.
I will be putting these on eBay on Friday night unless someone contacts me about them.
