Are the Equisense sensors shockproof?
The Equisense Motion, Motion Essential and Motion S come with an official certification: IK08.
The IK Code determines the degree of protection of a material against mechanical impacts. Your Motion is protected against a shock equal to a 1.25 kg mass falling from a height of 40 cm, corresponding to 5 Joules of energy.
That means you do not have to worry if your horse has a tendency to knock a jump with their girth. Your attachment and your Motion/Motion S won't be damaged.
