It is a deployable item that jams enemy radars within its effective radius, similar to the Jammer from Call of Duty: Black Ops. The Scrambler can be picked up and replaced at any time.
Another feature of the Scrambler is that when its user is within the Scrambler's radius, it grants an effect resembling the perk Blind Eye. Since the secondary effect of the Scrambler resembles Blind Eye, using this equipment with a different Tier 1 perk is a viable option. Similar to the Portable Radar, the effective area of a deployed friendly Scrambler will appear on the whole team's radar, allowing for tactical team use. The Scrambler is not affected by enemy EMPs.
The effective area for the Scrambler is very low, only about 5 meters.
