    • According to one aspect of the present disclosure, a device and technique for impact detection and indication is disclosed. The device includes a housing; a mass member located within the housing, the housing configured to enable movement of the mass member from a first position to a second position within the housing in response to receipt by the housing of an acceleration event; and first and second spring members disposed within the housing and configured to bias the mass member to the first position, wherein, in response to receipt by the housing of the acceleration event, the mass member is configured to overcome the biasing force of the first spring member and move from the first position to the second position, and wherein each of the first and second spring members extends across a medial portion of the mass member.
