For twenty years "Trackman numbers" has been shorthand for the truth, and the iO is the company's answer to a fair complaint: its outdoor radar units were never designed for a 12-foot garage. The iO is built for exactly that room. Ceiling-mounted, it fuses radar, infrared and high-speed imaging to produce real-time 3D spin and club data — the multi-sensor approach is what lets it deliver Trackman-grade output in a space where radar alone would be guessing. Practically, the mounting position is the whole point: the floor stays clear, there's nothing to move between clubs, and the bay looks like a room rather than a workshop. The price is what it is. At this level you're not comparing feature lists with a SkyTrak; you're deciding whether the brand's data standard is worth roughly seven times the entry point — which, for a teaching professional, a fitter or a commercial bay, it can straightforwardly be.
