Unless you’re in the armed forces, you’ll probably never need the Black Rad Radiation Detection Watch by Special Ops ($1500), but it would be an awesome conversation piece. Built to MTM’s exacting standards, the Black Rad includes a counter that detects harmful ionizing radiation. The Geiger-Muller tube can track radiation doses from .0001 to 0000 millisieverts (mSv). You can set your maximum radiation threshold and an alarm will sound when this level is hit. The Black Rad is water resistant to 330 feet and only 1000 units will be made.
