Why XTC Data Book
Across the Course rewards precision — not just in your position and trigger control, but in your record keeping. A paper data book gets you through one season; it doesn't tell you how your 600 yard zero has drifted over five matches, or whether your called shots actually match your hits.
XTC Data Book keeps every match in one place, on your phone, so the patterns show up on their own — your real zero at each distance, which conditions give you trouble, and whether your calls or your group center need the work.
