The rugged housing of the OPR 3101 is sealed to IP54 standards and holds up well in environments where water and dust resistance is required. The OPR 3101 withstands multiple drops of up to 2 meters (6.5 feet) onto concrete and features a trigger guard to prevent accidental scans, yet the ergonomic grip provides the user all-day comfort. The OPR 3101 uses the widely available and reliable Bluetooth wireless communication protocol which allows the scanned data to be instantly transmitted to any Bluetooth capable device. Scanned data is stored onboard the OPR 3101 in case the Bluetooth receiver moves out of range or is temporarily unavailable, thus preventing data loss as well as retracing time lost, contributing to continuous mobile working. A large and bright LED along with an adjustable tone provides a good-read indication especially when operating in low-light or noisy environments.
