The unique features of this board make it perfect for professional use.  The features:

  • EXACTLY resembles an ordinary brown Masonite clipboard such as we’ve seen all of our lives. 
  • You can peek the information in less than a second.
  • Nothing is added or taken away.
  • I’ve eliminated the "Visible Panty Line" bulging or wrinkling of the surface that occurs with other boards.
  • An ultra-sensitive impression is obtained due to my propietary "Brown Hornet Principle.".
  • Extremely durable under real performing conditions.


The manufacture of the Brown Hornet represents several hours of time and very specialized materials, skills and procedures. 

The Board

is a 6" x 9" Masonite clipboard. I retrofit an existing clipboard with an impression-capturing technology that I devised in 1994 that involves magnetic vinyl and Magic Slate. NOTE: This is not magnetic detection film that uses a magnetic pen. You can write with anything.

The Impression Surface:

Is a sensitive Magic Slate material split to an ultra-thinness, that covers the majority of the inner surface. Therefore, the entire surface of the board is hot. Due to the construction of the board, there is no "visible panty line" to give anyone a clue that it is anything other than an ordinary clipboard.


The Brown Hornet can be used for pre-show information gathering or for real time, during the show.  During showtime, you have quite a bit more control over the audience volunteers and don’t have to worry about someone trying to peel away the front of the board.
