ABSTRACT:
A beam of electromagnetic wave is suspended at an adjustable distance above a floor or an ice surface by a mechanism that generates electromagnetic wave energy and detects that same energy bounced back from a reflector plate placed a distance apart from the generator source. This beam of electromagnetic transmission suspended across the distance between the transceiver and reflector keeps an electric switch open and an electric alarm disabled or silent. Whenever the invisible beam is broken or cut by any obstruction, such as a skate's boot or leg, the alarm mechanism is energized and it will signal an interruption. The alarm signal indicates how high the skater did not reach, so that a practicing skater can be certain of step by step upward progress by constantly trying to keep the alarm off or silent.
