An acoustic touch apparatus that utilizes the transfer of surface acoustic waves from one surface, through the touch substrate, to another surface to enable multi-touch capabilities. The optic has an axial thickness that is less than 1,000 microns. As the data is entered, it is stored in a central database, typically through a dedicated connection between a client running the application and the database. The invention also relates to treestands and archery accessories having a low noise profile.
