Scout Drone

A faster flying drone that looks ahead for you. Crafted from glass, a Blank Chip, an iron ingot, redstone, a feather and a spyglass.

What it does

Scout: flies ahead of you, also in tunnels, and marks exposed ores and hostile mobs within about 16 blocks. Marks are small particles on the marked blocks and mobs, shown only to you, and fade after a couple of seconds unless refreshed.
Danger alert: chirps when a hostile mob comes up behind you.
With an Ore Filter chip it marks only ores; a Range chip makes it look further.
A Lamp chip works on the Scout too.
