The XTAR SD2 is a compact 4-colour dive beacon for signalling and marking underwater. Choose from white, red, blue and green light across 9 constant, flash and strobe modes, making it easy to spot a buddy, mark a float line or tank, or keep track of each other on night dives. Up to 100 lumens keeps the signal clear, and it runs on either a 14500 Li-ion or a standard AA battery. This set comes with an AA battery, so it is ready to clip on and dive.
