Annabeth Chase owns this shield. This invention was noted in Daedalus' Laptop, which he gave to Annabeth before he died. It can show any location the owner wants as long as they concentrate enough. Percy Jackson states that he got motion sickness the first time he used it. Beckendorf made it for her, although Annabeth only hinted at it because his girlfriend, Silena Beauregard, was at the scene.
During Annabeth and Percy's one-month anniversary picnic, they use the shield to hold the cheese and crackers while it is in its plate form. After Hermes has gone, Annabeth tosses it in the air and it becomes a full-sized bronze shield. She uses it to find Cacus, the fire-breathing giant. In battle, Annabeth uses the shield to smack Cacus' backside, but Cacus grabs the shield and crumples it like paper.
