Mine was purchased about 6-mo before they came out with the chain-rode combo. Mine you could use chain OR line. Figured I use it until it broke, then replace it with a combo unit. So much for plans!
It was free-falling, but I found it worked better to have someone speed up the free-falling. I often anchored in swift currents.....
The main thing I didn't like was it required greasing one-a-year. No zirt fittings, so it had to be removed and taken apart to grease, then reinstalled. A big hassle! Otherwise, quality was fine.
