This machine requires 0.1 PPS to function. If placed ontop of a ore vein it generates a visible waypoint on screen that shows the location of the machine along with the type of ore vein. If a sign is placed next to the machine then the machine can function anywhere and will display the text on the sign instead.
This machine requires a very small amount of power. Basic Laser Energy Transmitters can be used to power this machine and save costs compared to higher tier energy transmitters. Useful for marking ore vein locations that look useful!
