I thought last night to sell you mine but changed my mind when I found out that Argo Navis kit for my 12" Dob comes only with digital circles and cables without handheld computer

(
So I'll rather wait and save money for good EQ6 with GoTo.
I bought mine "digital angle meter" at Bunnins in Midland a few months ago. Its in the tools section and the problem is when you ask people there about it they didn't know what it was. I even printed picture from the net to show them what I want and no luck.
I spent some time looking around and I found it just oposite the counter. They said that it should not be there but the good news is I got it.
Sometimes you got kids working there and they have no clue what you want, so its better for you to look around in that case.
