Measure Noseband tightness, bit diameter and shank length with one device.
ISES recommends that a minimum spacing must be achieved between the noseband strap and the horse's nasal bones. It is encouraging to see that an increasing number of sports governing bodies are introducing new rules to this effect, with several countries specifying a spacing between 1.5 and 2 cms.
Research to determine the ideal adjustment of the noseband is ongoing, but in the meantime, the ISES taper gauge will help riders ensure their noseband is not overly tight and complies with the new rules. The ISES taper gauge is a tool that can be used to check the minimum spacing is achieved.
That all equestrian sports should require that the tightness of any noseband is checked by a steward at the nasal midline. For fairness and objectivity, a taper gauge inserted under the noseband should be used for this purpose. The taper gauge should be placed without force and be clearly marked to show the desired stop which, in alignment with established industry guidance, is the dimensions of two average adult fingers. Riders should be advised and encouraged to use the same gauge in practice.
