In *Avengers: Age of Ultron*, Captain America has some sort of magnetic thing to call the shield back to him (kind of like how Thor can summon his hammer).

[![Gif showing Steve stood in the forest in Sokovia; he has his left arm stretched in front of himself and activates the magnets on the back of his hand and forearm; the shield attaches to them from the ground](https://i.stack.imgur.com/Tjo2M.gif)](https://i.stack.imgur.com/Tjo2M.gif)

From the [wiki](https://marvelcinematicuniverse.fandom.com/wiki/Captain_America%27s_Shield#Ultron_Offensive):

> Tony Stark created for the Avengers many new gadgets to fight HYDRA. One of them was Captain America's new uniform, that possessed strong, electromagnetic panels on each of the glove that allows Captain America to retrieve his shield more easily.

Then, unless I'm mistaken, he no longer has any such device in *Captain America: Civil War*. For example, during the opening fight in Lagos, Nigeria, the shield is kicked away from Captain America and I immediately expected Cap would summon it back to his arm but he didn't, he just kept fighting hand to hand.

Is there any *in* or *out of universe* reason they got rid of it?

If it is used in the movie and I just missed it, please let me know when it happens, etc.
