The Pop Pack multi-variable and reactive targets are developed by a Navy SEAL to facilitate cognitive shooting drills, refine marksmanship, and add another degree of fun to a day at the range. Pop Packs are available in a box of 10 packs. Each pack has 10 unique variable arrangements consisting of different colors, & shapes. This variety is great for advanced defensive shooters practicing 'call-out' drills. Place the packs down range, and when the variable is called out from the firing line - race your friends to identify and engage the designated target! Not only is it a lot of fun, but it also reinforces positive identification as well as engaging the target until it is completely impacted. The end result is a highly visible pop! of environmentally safe gel that is water soluble and will not stain your clothes. Pop packs illustrate the nuances of shooting, and are a great way to introduce children and beginners to the sport.
