Digi-Shock G has given us a method to monitor and record impacts to our heavy cable products that can get damaged in transit if mishandled. The Digi-Shock mission control software allows us to see when impacts exceed our threshold for damage. This has been a great product for us and has helped minimize shipping damage. The support team at Impactograph is always helpful and friendly.
