Rebreather

The Rebreather is a piece of head gear in Fallout: New Vegas.

Characteristics
The provides a Damage Resistance of 3 and grants unlimited oxygen while submerged underwater. The player cannot drop or sell this item, and the condition will never degrade. It fills the glasses slot, so it does not prohibit the wearing of head gear that only covers the top of the head (i.e., combat helmets). It cannot be worn with certain helmets.

Location
The item is received from Jack at Nellis Hangars upon initiating the quest to recover the B-29 Bomber from the bottom of Lake Mead, if the player has the proper science skill of 45, or a Pressure cooker.
 * There is a Pressure cooker at Fields' Shack just before the Nellis Air Force Base Artillery Field.
 * A pressure cooker can be found in the kitchen of the Lucky 38 Presidential Suite (top shelf above the counter).
 * A pressure cooker can be found in the Cap Counterfeiting Shack.
 * A pressure cooker can be found in Doc Mitchell's house in Goodsprings.

Bugs

 * After the quest is completed, the Rebreather is still marked as a quest item, so it can't be sold or dropped.
 * You may also obtain the Rebreather upon completion of the quest.
 * The has clipping issues with facial hair.
 * Due to the hitbox covering the entire head it effectively becomes a 2nd helmet when worn.
 * Normally with this item equipped (or any other DR source active), the DT display will toggle between DT and DR. However, you may encounter a glitch where your damage threshold will only be shown in your Pipboy if the rebreather is equipped. (Confirmed)
 * It's possible that the H2O display doesn't fade away when getting up from the water. The cause is unknown but you can fix this issue by just simply removing the hud and then adding it again.
