Who each one is better for

Honest persona fit, side by side.

Better for Spica 3

  • Space-Constrained

    It sits beside the ball, so nothing has to fit behind the golfer, and GolfJoy's indoor minimum is 2 yards from the ball to the screen. It packs up and moves, too.

Better for iO

  • Showroom

    Trackman is the reference standard. The iO brings that ecosystem to home buyers at half the Trackman 4 price, ceiling-mounted for clean install. Brand cachet alone justifies the buy in some showroom contexts.

Both fit
