Hole Sensor was a device used in The New Adventures of He-Man.
The Hole Sensor was invented by the four Scientists of Primus to detect holes in the planetary shield around Primus. Alcon went as far as to proclaim it the 'greatest invention in history'. However, each of the four scientists began to think up other uses for the machiney.
Alcon wanted it to san the count the total number of stars in the Tri-Solar System. At the same time, Krex programmed it to chart the history of scientific knowledge. Alcon felt it had to speculate on the future instead. Soon they began to overload the machine with different functions running simultaniously and the machine began to fall apart.
Alcon immediately notified Master Sebrian by Vision Phone that they could no longer detect any holes in the shield.
