The Xtar SD1 is a compact lightweight diving torch suitable for underwater depths up to 100m, featuring four lighting outputs and is also handy for outdoor lighting. 

With four colour outputs and eight modes the SD1 has a variety of uses. To turn the torch on simply twist to the right and to turn off twist to the left. Cycle through the modes by quickly twisting the torch head back and forth, cycling through white, white flashing, red, red flashing, blue, blue flashing, green, and green flashing outputs. If the SD1 is off for more than five seconds, it maintains its current output instead of progressing to the next. This memory mode feature avoids the need to cycle through all outputs, as the SD1 recalls the last used setting.

The SD1 is powered by a 650 mAh 16340 lithium ion battery which is included. When the battery becomes low the torch will lower the lumen output to let you know the battery needs charging.

Included is a carabiner hook to make easy attachment, perfect for hands free lighting.
