I think there are a few videos on you tube (quite possibly under pessoa rather than mark todd system).
If you have never used one before I would strongly recommend getting some help from an instructor or groom who has experience using one first. They are super but can cause problems if used/fitted incorrectly.
Hi Great thanks for your help. Hopefully I'll be able to find one.
Ive used them before but never had to fit one. and only used them on horses that has used them before whereas this time im using it on my own horse to build his back use and try to get him off the forehand.
