Yeah they had the technition showing them how to use the machine, and used me as a ginea pig, they said I gave a perfect scan as Im slim, and the baby was in a great position. This ment I got a really long scan, and they tryied out all the machines features. One of which was to make a movement sensor that made the heatbeat flash in a different colur each time it beated, so you could see all the chambers of the heart flasing red each time its heart beat!
