Helmet manufacturers warn users that their product is good for one impact and one impact only. After that, the helmet’s shell and impact-absorbing liner may be compromised.

Visual examination may or may not reveal shell damage. Visual examination WILL NOT reveal liner damage. A damaged shell or liner greatly reduces the helmet’s ability to absorb further impacts.

Helmet damage can occur in a sporting accident, or when the helmet is not in place on a your head, for example if it is dropped onto concrete from several feet. For this reason, manufacturers and government authorities instruct users to either return the helmet to the factory for inspection, or discard the helmet, if it has seen a significant impact. You should see a label to this effect inside your helmet.

Yorba Safety Concepts developed the Shok-SpotR™ to help you better monitor this type of damage.

Please Note: It is possible to damage your helmet without activating Shok-SpotR.

Shok-SpotR™ was designed to help you monitor the possibility of impact damage - a type of damage that is often invisible. But there are other types of damage such as chin strap tears, chemical damage, and puncture damage. With a sharp enough object, it's possible to puncture your helmet's shell with relatively little impact. This may or may not activate the sensor. Also, a damaging impact below an imaginary line called the helmet test line may or may not activate the sensor. For more information on this subject, refer to our Frequently Asked Questions page.
