Amazing accuracy!
This little box is astonishingly accurate. Took my car to Bandimere and ran a 9.40, this thing recorded 9.38. In fact, every measurement this box takes is within a few hundredths of a second from Bandimere’s clocks. And that was many runs with repeatable accuracy. That’s very impressive to me for $150!
Set up is so easy that they don’t really include many instructions. Link it to your phone and it just starts recording when it sees movement, then stops recording when the vehicle stops.
I thought it would have to be calibrated by placing it flat then vertical and all that. Nope, good to go right out of the box. I thought it would have to be placed on a level surface. Nope, my console sits at a slight angle and it still works perfect. It has two magnets and will stick to any steel surface. But they give you two sticky steel pads if you don’t have a steel surface to stick it to.
