- Stackmat timer
Stackmat timers are the official timing device for speed stacking and
speedcubing . There are currently two stackmat versions. The "first generation" has the touch sensitive pads level and built into the mat. The "second generation" has touch sensitive pads on a timing device that can be detached from the mat. The pads are raised slightly higher than the mat.External links
