You've found the Laser Detonator Ulysses spoke of, a piece of Pre-War tech that can detonate the nuclear warheads scattered around the Lonesome Road. You can use it to open new paths, kill your enemies from afar, or even discover secret loot caches. Just point it at a warhead, hold down the trigger, and watch the explosion. If what Ulysses said is true, you'll need this to advance, which means there must be a warhead blocking the way forward. You'll need to find the correct warhead and detonate it.— In-game message when picking up the detonator

The laser detonator is a "weapon" in the Fallout: New Vegas add-on Lonesome Road.

Background

The laser detonator is a detonator powered with microfusion breeder and using laser illumination to trigger the nuclear warheads found around the Divide. It fires a series of coded pulses of visible red laser-light similar to a laser designator and therefore dealing does not deal any damage. When the laser is aimed at a nuclear warhead, it causes it to heat up, eventually leading to the chemical explosive inside detonating, scattering radioactive material around.

It is similar in design and shape to the Compliance Regulator. It has a green coloration with red trim at the barrel, and a glowing yellow light next to the keypad and screen.

Characteristics

It fires a continuous beam similar to that of a laser rifle or pistol, except for the duration. It does not deal damage and therefore serves no purpose other than destroying nuclear warheads. This weapon is essential for completing the Warhead Hunter challenge.

Notes

  • The laser detonator deals no damage to anything other than nuclear warheads.
  • Given that this item has a very long effective range, one can stand a safe distance away when detonating a warhead, as they explode violently and may trigger several chain reaction explosions as a result. This is especially true in Hopeville, where most warheads are in military trucks that have been used to make car barricades.
  • It requires no ammunition, as it uses a microfusion breeder.
  • The laser detonator has the highest item HP of any weapon in Fallout: New Vegas.
  • The screen and lights on the side are identical to the ones found on a Red Glare.
  • The laser detonator is a quest item, so it cannot be dropped or sold.
  • Because it is a laser, it can be used to ignite leaking gas or set off bear traps.
  • Drawing this in casinos still nets the Courier infamy.
  • Upon detonating all nuclear warheads, the laser detonator is still considered a quest item and therefore cannot be dropped, sold, or placed into any storage devices. As such, it can be taken to the Sierra Madre. The quest flag can be removed by using SetQuestObject xx007670 0.

Bugs

  • Icon pc.png Icon xbox360.png If the player character has Euclid's C-Finder, there may be some interaction between it and the laser detonator to the point where the laser detonator will not blow up the warhead. If this occurs, drop the C-Finder, blow up the warhead and pick up the C-Finder again.[verified]
  • Icon xbox360.png Sometimes when firing the laser detonator, the beam will disappear and the gun will still shake as if it is being fired. It will not blow up warheads while doing this, and to fix it one only has to stop firing and fire it again. [verified]
  • Icon pc.png Icon ps3.png Icon xbox360.png The mesh file for this weapon points to a specific texture for the yellow circle on the side - intended to show an oscilloscope display identical to the Gabriel's Bark variant of the sonic emitter. Since the texture path is incorrect, this part of the laser detonator simply shows up as a bright yellow circle.
  • Icon pc.png Icon ps3.png Icon xbox360.png When using an infinite ammo glitch (Equip weapon, hotkey, go to ammo, hotkey ammo) some types of ammo (Mini nukes, rockets, missiles) have the ability to be fired from it at a very fast pace, while also not consuming any of the ammo.[verification overdue]
