XTAR SD1 Multi-Colour Dive Beacon
Model Series: Essential Underwater Signaling & Safety Identification Matrix
The XTAR SD1 is a professional-grade, multi-spectral dive beacon engineered to provide high-visibility signaling, team identification, and emergency location tracking in diverse marine environments. Compact, lightweight, and ruggedly constructed, this beacon is an indispensable tool for both technical and recreational divers, offering a versatile suite of eight distinct lighting configurations—including four color channels (RGBW) available in both steady and strobe modes. Forged from aircraft-grade aluminum with an anti-corrosive finish, the SD1 is depth-rated to 100 meters, ensuring reliable performance during deep-water excursions, wreck penetration, or low-light night dives. Whether deployed for surface signaling or underwater communication, the SD1 provides an essential safety footprint that keeps the dive team linked and visible.
Technical Signaling & Operational Features
- RGBW Multi-Colour LED Array: Versatile four-color emitter system (White, Red, Blue, Green) offers eight distinct modes (4 Constant / 4 Flashing), providing clear visual signaling and team-based identification
- Intuitive Twist-Switch UI: Precision mechanical twist-interface allows for rapid, reliable mode selection even while operating with thick thermal or dry-suit gloves
- Intelligent Power Management: Low-battery detection system automatically reduces luminous intensity to provide a distinct visual cue, ensuring the user has sufficient time to conclude the dive before shutdown
- Smart Mode Memory: Integrated circuitry remembers the last utilized signaling mode after a five-second power-down, allowing for instant, pre-configured reactivation
- Dual-Source Battery Compatibility: High-efficiency power platform accepts either the provided 16340 USB-C rechargeable cell or standard CR123A primary lithium batteries for global field logistics
- Depth-Rated Structural Integrity: IPX8-certified housing constructed from anti-corrosive, aircraft-grade aluminum, pressure-rated for reliable operation down to 100 meters
- Multi-Environment Versatility: Rugged design suitable for both underwater signaling and surface-side activities, offering reliable beacon tracking across varied expedition landscapes

Technology
MULTI-SPECTRUM OPTIC-TRACKING DYNAMICS
Underwater, white light is often rapidly filtered by the water column, and high-intensity strobe beacons can cause distracting "light noise" in team communication. The XTAR SD1 optimizes visibility by offering four distinct color channels (RGBW). Divers can select Red or Blue for reduced glare during night dives, Green for high-contrast tracking in emerald-tinted coastal waters, or White for maximum intensity. By separating these signaling channels and providing both steady and flashing states, the SD1 allows teams to establish distinct visual codes—assigning specific colors to individual divers or equipment caches—effectively eliminating ambiguity during multi-diver decompression stops and complex wreck navigation.
