BBCOR (-3) Alloy vs. Two-Piece Composite Bats + Pocket Radar & Dual-Wheel Pitching Machines: Building a Backyard Velocity Lab
Pick the right bat construction, measure real velocity, and set up a cage that trains reaction time.
Executive Summary & Lab Winner
One-piece alloy BBCOR bats are game-ready immediately and stiff; two-piece composites cut sting and need a break-in. Pair a radar to measure true mph with a dual-wheel machine set to your opponents' perceived velocity, and train inside the ~100–150 ms decision window.
