Impact indicators are simple, tamper-evident devices that show when a shipment has been dropped, mishandled, or exposed to damaging force. While they all detect impact, each one is designed for a specific application. Stuck For®, a brand of Good Life Innovations Ltd — an authorised SpotSee® distributor — supports businesses worldwide with expert advice and precision monitoring solutions.
Why Use Indicators?
The presence of a bright yellow SpotSee label significantly reduces mishandling by couriers. It transitions your shipment from "just another box" to a monitored asset.
Safe Transit: Window remains white.
Impact Detected: Window turns red.
