This Level 2 Myler bit (MB 04) is for horses or ponies established in basic training. It utilizes less tongue pressure and more bar pressure than level 1 bits.
This bit has a low port, copper inlay on the mouthpiece and hooks. The slight (1/4") port allows for more tongue relief than Level 1 mouthpieces. The hooks are slots that keep the bridle fixed in place and create two rein positions.
