The LaserLyte Reaction Tyme Targets have both a reactive and interactive mode that can be used with any LaserLyte laser training product. When set to constant ON mode, the targets react by flashing and beeping to let you know that you have hit them successfully. When set to “Reaction Tyme” mode, the targets actually signal you that it is time to shoot them and then react when they are hit by the laser beam. By using multiple Reaction Tyme Targets, you can create a Figure 8 Drill in virtually any space safely and conveniently, as demonstrated in this video by Rob Pincus. LaserLyte Reaction Tyme Targets respond to any LaserLyte training laser.
