- "The commanders here are working off Plutarch's holograph. Each has a handheld contraption called a Holo that produces images like I saw in Command. They can zoom into any area of the grid and see what pods await them."

A Holo is a handheld device used by the rebels to show locations of known pods hidden in the Capitol streets.[1]
History[]
The holograph installed in the Holos was obtained by a rebel and handed over to Plutarch Heavensbee when they left the Capitol. Each commander in District 13 was issued a Holo to aid in their infiltration of the Capitol, including Boggs, who led Squad 451.[1]
Squad 451 gathered around a Holo projecting the sites of all known pods in the Capitol.
Squad 451 attempted to use the Holo to take over a block by triggering its pods from a safe distance.[2] However, after Boggs was mortally wounded by a land mine, he transferred the prime security clearance over to Katniss Everdeen. This bypassed the squad's second-in-command, Jackson, and effectively made Katniss the new squad leader. Afterward, Jackson helped Katniss operate the Holo[3] and taught her the basic commands needed to operate it.[4]
While keeping watch in the Transfer, Katniss and Pollux used the Holo to investigate nearby pods.[4] Despite attempting to find a different route, they were soon pursued by lizard mutts, and Katniss detonated the Holo into the remaining mutts after Finnick Odair was killed.[5]
Description[]
A Holo is used to produce a holographic image of the Capitol, with pods represented by flashing lights[1] both above and belowground. This does not show pods the rebels were unaware of. The most basic commands consist of entering the coordinates of the nearest map grid intersections.[4] It cannot send nor receive signals.[1] A Holo also has fingerprint recognition and a password for additional security. When Boggs transferred the Holo's prime security clearance to Katniss, a green shaft of light burst from the device and flickered over Katniss.[3]
A Holo can only be activated by a specific commander's voice. Once on, it responds to the other voices from the squadron so someone else can take over if the commander is killed. If anyone in the squadron flicks the switch and says "nightlock" three times in a row, the Holo explodes everything in a five-yard radius, which serves the purpose of killing them if they get caught and preventing the Holo from falling into enemy hands.[1]
