In addition, each colour beam can be used as an AFO focus light, which automatically shuts off when the unit’s electronic flash sensor detects a flash. With a wide 100-degree beam angle for greater illumination, the flood and red modes have adjustable brightness levels of 25%, 50% and 100%. When used in areas with ambient temperatures above 50°C, the brightness is automatically reduced to 20% to protect against overheating. 

For a more convenient way to monitor battery levels, there are four battery indicator lights (blue, green, red and flashing red) near the on/off button. It is easy to operate with one hand and is depth- rated to 100m (330ft). Weighing 420g on land and 195g underwater, it is powered by a high-capacity 18650 lithium battery, which has a high level of safety and lasts twice as long as a standard battery.
