Hi, I'm new to this board, and I wondered if anyone has used a mechanical hackamore with their horse while trail riding. I bought a horse several months ago that has been trained on the hackamore and I am having trouble stopping him. I have heard that you must have sensitive hands when using this type of bridle but Rebel (my horse) seems to ignore many of my requests to slow down and stop. He is an 11 year old arabian gelding.
