I got a pitch back when I was a kid. I used it for years, repaired it many times. It worked great and was incredibly durable. It is long disintegrated but I still have the instructions (See image at end of the post)! The net had 24 S-hooks to attach to the frame. You could stand far away and try to hit the center every throw.
Missing the net ended up in long runs to get the ball and start again. This was a good incentive not to miss. You could angle the pitchback for flys, line drives or ground balls. I liked to stand really close and throw as hard as I possibly could. This honed my skills at snagging balls that were returned at a rapid rate.
I also enjoyed having to jump or leap for line drives or grounders and getting an accurate throw, back to the net, in as little time as possible. This meant another return was coming fast which would wear me out. Now they have ones that if you throw low you get a fly and a higher throw gets you a grounder or a line drive.
