Serving

We rookie Pickleball players at my Saturday session are pretty unreliable at accurate serving so today our tutor brought along a ball machine. It looked like a Dalek. It rumbled and puffed and the ball net wobbled a bit then it spat out balls at we unsuspecting victims who had to return the serves backhand.
I was half expecting it to say “Exterminate”!
In the photo it has just belched out a ball at about 40 miles an hour and way too low for my liking.
It can send them at up to 65 miles an hour. 
All controlled by an App. Of course.
