Proximity Bomb

These bombs are dropped behind your ship, waiting to explode when something gets near. ---Descent Manual description

The Proximity Bomb is the third type of secondary weapon in Descent and Descent II. The player can have a maximum of 10. When fired the ship places one bomb just behind it. Unlike the other secondary weapons, this bomb is used to set a trap for an enemy to run into causing the same amount of damage as a Concussion Missile. The bomb also detonates if the Material Defender's ship runs into it, if it is left for around a minute or if any projectiles make contact with it. Those bombs are ideal for taking out enemies that come from Robot Spawners, but are not effective in the middle of a firefight.
