Airspace Denier


 * The Airspace Denier is a Support Item and is similar to the Bear Trap in that it limits movement and makes vision obscured, but is triggered by being airborne. Eligible gadgets are Spring Boots, the Glider Rig, Inflatable Insoles, the Grapple Gun, and the Jetpack.
 * Simply jumping and using a trampoline can also trigger it, and thus they are good spots to place your Airspace Denier.
 * Placing them on air-vents are also recommended, and since you get a notification when they are triggered, you can chain kills with ease.
