We researched laser tag equipment and brought in a consultant to help us choose the best equipment on the market and made in the U.S.A. The vests come with two speakers to enhance the actual experience, plus the vests vibrate when you are being tagged. The game computer will congratulate you on an excellent tag. The Phasers have dual burst buttons that allow you to fire single or rapid bursts when you pull the trigger. (The requirement to use both hands also adds to the safety of the game.) The game computer lets the teams know when the game is tied or close, and informs either team that their base is under attack. All this is set within a 6,000 square foot, black lit arena; Ramps, fog, strobe lights, appropriate music, and a disco ball really make the place rock.
