Description, Usage & Why Every Diver Needs One

Illuminate your dive – wherever, whenever.

The XTAR SD1 is a compact multi‑colour beacon built for safety and versatility. Designed to be your go-to companion, whether you're night diving coral reefs, signalling dive buddies, or heading ashore after a dusk dive, this beacon does it all.

Logical reasons to dive with it

  • Stand out underwater – choose from white, red, blue, or green constant or strobe modes to adapt to visibility, signalling or preserving night vision.

  • Fully rugged – waterproof to 100 m and impact-resistant up to 1.5 m, it's engineered to handle the harshness of the deep 

  • Long-lasting power – up to 16 hours on CR123A or 10 hours on 16340 lithium in flashing mode—outperforming many dive strobes 

Emotional reasons to own one

  • Peace of mind – keep tabs on your buddy in murky or vast conditions.

  • Confidence on every dive – easy-to-use twist interface lets you switch modes even with gloves on.

  • Tiny yet mighty – at just 27 g and 66 mm long, it won’t weigh you down 

Every diver, from weekend explorers to technical professionals, will appreciate the assurance and visibility this beacon brings to their kit.
