Storm Tactical Pocket Data books are our most compact books. They were designed for use in the field and for tactical rifle competitions, where a lightweight, portable Data Book is needed. They are smaller than other Data Books, and yet are packed with information and Data Entry fields across 210 pages. Due to innovative design and layout, the data entry fields and data are large enough to be easily used at both the rifle range, and in the field. These books were two years in development, with elite military and law enforcement units.
