Note: Since Update #39, this skill has been replaced by Jack Of All Trades and Tactical Mines basics, which together increase the trip mine radius equal to the aced version. This skill is still available on the Playstation 3 and XBox 360 versions.
|Basic (4 pt): The radius of trip mine explosions are increased by 25%.|
|Ace (8 pt): The radius is further increased by 75%.|
Quite simply, this skill increases the range over which trip mines deal damage to enemies and destructible objects on the map. This increase in radius does not affect how many boxes are destroyed when trucks are blown open on Transport heists, nor does it affect the contents of safes.
Because of the explosion mechanics in PAYDAY 2, the trip mine deals lethal damage to anything in its area of effect, with the exception of Death Wish Bulldozers. Damage does not diminish or intensify in relation to the target's distance from the mine when it explodes.
If a player intends to use their trip mines only as shaped charges, this skill has no effect on gameplay and should probably not be purchased. However, for those adept at using trip mines as offensive weapons; this skill will be needed to make trip mines more effective on later levels.
Even with the basic upgrade, trip mines will be capable of wiping out a large group of enemies nearby, roughly the size of the front lobby area of the Harvest and Trustee bank. Once aced, trip mines are capable of clearing just about any enclosed space of hostiles in one go, with the slight exception of a Bulldozer at full health. However, because of Payday 2's largely urban setting, the aced version of the skill will rarely be of benefit as most areas can be covered by a single mine for maximum damage with the right placement using just the basic version. So for the sake of conserving points, it is best not to ace this skill.
Using one or both of the blast radius upgrades also make trip mines more viable as anti-swarm weapons by turning them off or setting them to sensor mode so enemies do not automatically trip them, and manually detonating them with a grenade or gunfire once a sufficient amount of enemies have massed near the mine.
