What was a "JumpMaster" Training Aid?

I was browsing this webpage and, at the bottom, there's a dead link to "JumpMaster -- a jump timing aid for skaters."  (URL = http://www.ucalgary.ca/~ippzapal/jumpmhome.html )

What was it?

I had to go way back in the Way Back machine to around 1999. I found no pictures, but I did find this text...

What is it?
The JumpMaster® was designed as a training aid for figure skaters. The guiding principle behind the design of JumpMaster® is that landing jumps consistently is dependent on consistant timing. The JumpMaster® is an electronic cueing device worn by the skater that signals the initiation of rotation and check out, two critical phases of the jump.

The JumpMaster® should be initially set by the coach or by consulting the table of jump timings included with the unit. It must be noted that the timings listed are used only as a guideline for each jump; the coach and skater should take a few moments to refine the timing as they work on a specific jump. Once a skater has determined the most effective timing sequence, these values should be recorded for future use.

Using The JumpMaster®
The JumpMaster® is worn on a web-style belt in the "numbers-up" position. The skater may notice that the JumpMaster® may emit tones while the skater strokes. The JumpMaster® has been tuned to be just sensitive enough to detect when the skater leaves the ice but unsensitive to the motion of smoothstroking. Skaters may choose to wear any headphone with a miniature personal stereo-style jack. The skater adjusts the timing to the desired settings by pressing the buttons above and below the numerical indicators and skates normally.

During a jump, the JumpMaster® emits two distinct electronic tones at the precise intervals set on the top of the unit. The first tone indicates that the skater should be in a rotational position. A rotational position is defined as the stance a skater takes to rotate quickly in the air: arms and legs should be retracted towards the body's vertical axis as closely as possible. The second tone is supposed to sound precisely when the skater returns to the ice following the jump. The second tone should be set to indicate initiation of the opened or check out position.

Thanks Bill.  Sounds interesting, but a little outdated with wireless earbuds and bluetooth.
