any of you kids notice zoro was using haki ?
"your weak cause you can only see with your eyes"
After the 2 year arc, Zoro and Sanji attained both the hakis attainable through training.
Kenbunshoku Haki (The ability to hear movements) [or Mantra on Sky Island]
Busoshoku Haki (The armor)
SO yes I can guess you can say he was using Haki, but not at the same time. Zoro was able to attack without just seeing things before hand. I don't think he used Haki at all. He just used his sensing skills.
