Buoy (Fallout 3)

Buoys in the Fallout 3 add-on Point Lookout mark the location of hidden containers in the waters of Point Lookout. Buoys are easily located in the fog due to their bells. The actual caches are found underwater, directly below the buoys. Breathing in water isn't easy - even for the lone wanderer. So keep an eye on the oxygen gauge or keep stims at the ready.
