If you have the Strikeman Laser Firearm Training System or Marksman Kit, you already have our standard, tabletop phone mount and tripod. The Pro tripod is an upgrade that allows you train anywhere with an extendable height of up to 4 feet. At Strikeman, we stand behind our product. Our system is guaranteed to improve your accuracy in 45 days, or your money back. Most of our customers report seeing improvement in as little as two weeks, though.
