 You know that Mantis X will put you through drills in your living room, in your air conditioning, in your office, wherever. They'll keep score. You'll track your progress. They'll give you feedback. It's like having a coach in your hands. The professionals use Mantis X because Mantis X will get you really fast and really deadly over enough time it will. Whether you're mega experienced or maybe you're just starting out. I'm too nervous to go to the range.
