Radar jammer

The Radar Jammer is an equipment item that scrambles nearby players' motion sensors and HUDs when deployed and also makes their screen flicker and flash as if they're taking damage. While it can create chaos for enemies, it has the same effect on teammates. In the September 2007 EGM magazine it was stated that the radar jammer is "mostly useless" because enemies in campaign mode do not use motion sensors.

References were found to it in the Halo 3 Beta code and its effect was seen in leaked beta footage. It was confirmed in the June issue of GamePro.

The Radar Jammer is identical to the Power Drainer, except for its reddish-brown metal color and a red under color instead of blue.

It has been seen dropped by a Brute with a Jetpack in the Halo 3 E3 2007 Trailer, confirming that Brutes can use more than just the Bubble Shields.
