Watch LessonGag Polo Big Ring
A gag works by lifting the bit in the mouth in order to encourage the head to be raised. Often used on strong horses that like to lower their heads in order to escape the action of the bit in the mouth and get very strong
When pressure is applied to the rein, the bit is lifted in the mouth and poll pressure is applied. The bit also rotates slightly in the mouth putting more pressure on the tongue and bars.
To be correctly used, it must be used with two reins one on the gag rein and one on the bit, only bringing the gag rein into play when needed, although most people ride on the gag rein only.
Functionality
A gag is intended to be used with 2 reins. One is connected at rein attachment 1 and the other on rein attachment two which is the rope. Having these 2 rein options regulate when the gag effect takes place. When rein attachment 2 is engaged it will apply quite a bit of pressure on the poll as well as creating slide on the mouthpiece which will create pressure on the corners of the horses’ lips as well as leverage on the mouthpiece.
