Hi,

I got my patriot system set up but my question is whether the small gray box needs to be attached to the wall or the user has to hold it on his/her hands. I've seen pictures of caves where people are wearing the goggles and holding a small cube on one of the hands. Is that the case? Also, does any vibration in the box (sensor) would be a problem to the receive the information from the computer?

Thanks,

Vinicius
