Hang the dates. Do not hang a novel.

Why a list beats a binder

Binders get opened when someone already grabbed an overdue mic. A due list is visible before the drawer opens. Overdue at the top. Due within 30 days next. No date at the bottom so you can see what you never scheduled.

Minimum columns

• Due date — the day it must be back or out of service, not the day you remembered.
• Status — overdue, due soon, ok, or no date.
• Name people actually shout: “0–1 mic,” not an internal SKU only purchasing knows.
• Serial or asset number.
• Location — crib, surface plate, the mill it never leaves.
• A short note: lab name, interval, “do not use if the sticker is torn.”

Reprint when something moves

When a height gage comes back, change the next due date and print again. White-out on last month’s sheet is how two techs argue about which date is real. Job Traveler prints this as a one-page PDF from the equipment list. It does not calibrate anything.
