Vibrabombs are special land mines designed to be detonated from the vibrations given off by the footfalls of walking BattleMechs. The mines can be set to variable sensitivities, only reacting to 'Mechs of a certain weight class by exploding directly under them. Their drawback is that the mines are ill-suited for 'Mechs that are significantly lighter or heavier than the set sensitivity. A lighter 'Mech won't set off the mines, while a heavier 'Mech will set off the mines too early to be effective. Vibrabombs are ineffectual against infantry.
Vibrabombs follow the same rules as conventional mines, with the following exceptions. When placed, Vibrabombs must be set to a specific mass, i.e. 40-tons. If a 'Mech masses 10 tons more or less than the set level, the minefield will not function properly. For 'Mechs of lighter weight, the minefield will not activate; a 30-ton 'Mech will not set off the mines. For 'Mechs heavier than the set limit, the minefield will prematurely detonate at a distance of 1 hex for each full 10 tons the 'Mech is over the set limit; a 60-ton 'Mech will set off the mines when it enters a hex two hexes away.
