I have an old Ace before the hands free......been meaning to update mine.Only problems I have had is the switch falling apart. Called them up and they send one right away. I like the ace because they don't pull the traps into your boat with the large boom, downside to that is they take up a lot of real estate compared to the Scotty.
I think if I had a smaller boat I might be inclined to go with the Scotty, especially if you are a fish while your soaking guy.
Got lots of room then get an ace, both local product with great warrantee.
