How loot chance works
The chance that a freshly spawned container, or a killed NPC, rolls at least one Seismic Sensor. Container chances are before inventory limits: a full crate can discard rolled items, while bonus scrap drops beside it.

One target at full health and contact range, vanilla settings, fresh melee tools. This target has no soft side.
How counts and times are worked out
The splash filter describes sharing damage across walls, not collateral damage to players or nearby deployables. C4 and satchels do not share construction damage even when loose. Counts are for one target; visibility and distance determine possible splash.
Times are exact for melee and for anything fired: swings times swing delay, or shots times fire rate plus the reloads that forces. For a charge you place by hand it is one second per charge plus the fuse, and that one second is the only estimate here. Melee tool counts assume fresh tools, because repairing lowers a tool's maximum condition each time and that rate is not in the files we read. Vanilla server settings, contact range, no distance falloff.

Per item at full condition. Green’s 60% boost needs 4 heavy fuses at the Power Plant; red requires maximum power (18 fuses).

How returns work
Component fractions are random rolls; Scrap fractions carry over between cycles. Worn items return less.

What to know
The output identifies explosion strength
The Seismic Sensor can monitor 1-30 metres. F1 and Beancan explosions output 1 power, explosive ammo and Satchels 2, and C4 and Rockets 3: useful for filtering an alarm circuit.
