The RevitaVet Poll Cap from RevitaVet Therapy Systems offers targeted red light therapy to address your horse's autonomic nervous system through acupuncture points. Relieving sympathetic stress in your horse offers many benefits, including a calmer, more relaxed animal. The Poll Cap addresses common ailments, including head tension, head tilting, teeth grinding, TMJ, problems of the 1st and 2nd vertebrae, and more. Softening and releasing the horse's poll affects the coordinating actions between the temporomandibular joint (TMJ) and hyoid bones, allowing your horse to be softer in hand and more athletic. The Poll Cap operates on 3 "AA" batteries and is completely cordless and hands-free. Simply place it under your horse's halter for a 15-minute therapy session or for use during stressors like farrier visits, travel, and while being tacked for competition.
