Attaching head sensor to a head accessory or helmet

Head sensor can be attached to almost any kind of head accessory or wear with hook&loop (Velcro): variety of hair bands, head bands or helmets. Choose what you use, or buy one of ACT Head Impact Tracker accessories specifically designed for it. What ever your head wear, gear or accessory of attachment, ensure the sensor is firmly attached, and can not move or get loose. Head sensor has to stay put and in place to give quality measurement.

The back panel of the head sensor has an adhesive surface that you can use by removing the protective film on top of it. We recommend that you use the adhesive surface to attach the hook tape to it, with which you can attach the head sensor to the specifically designed ACT Head Impact Tracker headband, ACT Head Impact Tracker Dock or other head accessory of your choosing with loop-side on it, or where you can attach loop side onto. Please note that the adhesive surface is very adhesive, consider carefully where or what you want to attach to it. 

If you consider attaching the head sensor to a helmet, refer to your helmet’s User Manual, Owner’s Guide or corresponding document to verify if it is possible. Always follow the helmet manufacturer's instructions on safe helmet use. Only use a helmet that meets the applicable safety standards when you use a helmet with ACT Head Impact Tracker head sensor. Please note that magnitude measurements will be affected by the helmet attachment: forces measured from the helmet are not the same as forces acting on a head inside the helmet.
