interesting comments, your mileage may vary in practice use.
I just went to their web site, mile marker's, and looked at the instructions. Looks like the same two levers that have 4 positions that they can be in. Plus the in out switch. Same winch I had and for some reason the morse code didn't work.
You needed to tell them what lever to free spool, then high or low speed. While it sounds simple, communicating that to someone while sitting at a steep angle and worrying about flopping was not fun. Many times they would flip the speed lever and or free spool it. When either of these things happened, I was either not going anywhere or in danger of going backwards. That is what I experienced running one for a few years.
The winch worked great, but second hand operator control was lacking. Not totally the original question, but my experience.
