Seismic Sensor
A small device that detects vibrations within a set range. Will output a different power value depending on the explosive type detected, ideal to know when your time has come.

A range means the last unit is a coin flip rather than a guarantee: half the recipe rarely divides evenly, and the recycler rolls for the remainder.
Tech tree
On the workbench 2 tree, available from the start of it.
No scrap price on the tree itself: every node ships with its cost overridden to -1 and the fallback is not recoverable from the files. The research table price above is a different number and that one is derivable.

Seismic Sensor has 200 health.
12 x Handmade Shell for 60 sulfur. No mix of tools beats it.
Cheapest explosive on its own: 4 x F1 Grenade for 240 sulfur, about 7s. That is what most raids actually run, because sulfur is not the only cost.

A seismic sensor has no soft side, so these are its only numbers. 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.
The chance that a freshly spawned container, or a killed NPC, gives you at least one Seismic Sensor. Best chance first.
