  • What Else Is Needed

    This handheld response device needs an electronic interface to function -- that converts the optical signals to standard computer interfacing signals. In most cases you will also need a long optical fiber extension bundle to allow this device to be used at a distance from the interface unit. Examples of the interface and bundle are shown below in the Related Products section.

    magnet safe This item contains no metal, nothing electronic, and nothing magnetic. It can be used safely in the magnet room.
