The X-am 5800 is small and lightweight, comfortable to wear, and easy-to-use, with large buttons for ease of use while wearing gloves. The display clearly shows important information, such as gas readings, alarms and time. The green D-light indicates that the unit is ready for use, with a simple interface. For added safety, the oxygen channel has four alarm thresholds, real pre-alarms, and main alarms for falling and rising concentrations.
