The Big Ring Gag is made with stainless steel 4-1/2" rings and a sweet iron mouth. The Big Ring Gag is stronger than the usual Loose Ring and Eggbutt as the ropes going through the rings create leverage which will exert more pressure through the mouthpiece whilst at the same time introducing more poll pressure.
The Happy Tongue is a solid mouth piece is curved and ported to give tongue relief. The Happy Tongue would be a good place to start if your horse is:
Shaking its head
Sticking its tongue out
Sucking its tongue back and as a result making an intermittent coughing noise
Trying to put its tongue over the bit
The rider will know immediately if this is the correct bit. Changing the cheekpieces would then allow the rider to adjust the level of control.
The mouth pieces is made from blue sweet iron, because it:
helps bit acceptance
is warm and sweet
Please note the blue will fade with use.
