The Cobra was designed by an avid volleyball player and tournament director for 2 main reasons: safety and ease of set up. When you're in the middle of a game, focused on the volleyball, you're not watching out for dangerous guy wires. This guy wire injury occurred in the middle of a volleyball tournament. After a trip to the hospital and 21 stitches, his comment was "I'm only glad it wasn't my neck!" Every volleyball coach has a story about guy wire injuries. Another common injury comes from stepping on the pegs that hold the wires down. Play safe! Play Cobra!
