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.\u003c\/p\u003e\n\u003c\/header\u003e\n\u003csection class=\"features\"\u003e\n\u003ch3\u003eTechnical Signaling \u0026amp; Operational Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRGBW Multi-Colour LED Array:\u003c\/strong\u003e 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntuitive Twist-Switch UI:\u003c\/strong\u003e Precision mechanical twist-interface allows for rapid, reliable mode selection even while operating with thick thermal or dry-suit gloves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelligent Power Management:\u003c\/strong\u003e 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart Mode Memory:\u003c\/strong\u003e Integrated circuitry remembers the last utilized signaling mode after a five-second power-down, allowing for instant, pre-configured reactivation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Source Battery Compatibility:\u003c\/strong\u003e High-efficiency power platform accepts either the provided 16340 USB-C rechargeable cell or standard CR123A primary lithium batteries for global field logistics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth-Rated Structural Integrity:\u003c\/strong\u003e IPX8-certified housing constructed from anti-corrosive, aircraft-grade aluminum, pressure-rated for reliable operation down to 100 meters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Environment Versatility:\u003c\/strong\u003e Rugged design suitable for both underwater signaling and surface-side activities, offering reliable beacon tracking across varied expedition landscapes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e\n\u003csection class=\"specifications-tables\"\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp; Operational Matrix\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eTechnical Parameter\u003c\/th\u003e\n\u003cth\u003eOperational \u0026amp; Physical Standard\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComponent Classification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eProfessional Multi-Colour LED Signaling Beacon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput Performance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e25 Lumens (White\/Green) \/ 10 Lumens (Red\/Blue)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDepth Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 Meters (IPX8 Pressure-Rated Housing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRuntime Matrix\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eConstant: Up to 6.5h \/ Flashing: Up to 13.5h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhysical Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e66mm (L) x 23mm (Diameter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem Net Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e27g (Excluding Battery)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/section\u003e\n\u003csection class=\"technology\"\u003e\n\u003ch3\u003eTechnology\u003c\/h3\u003e\n\u003cdiv class=\"tech-item\"\u003e\n\u003ch4\u003eMULTI-SPECTRUM OPTIC-TRACKING DYNAMICS\u003c\/h4\u003e\n\u003cp\u003eUnderwater, 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"kit-contents\"\u003e\n\u003ch3\u003eField Kit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x XTAR SD1 Beacon\u003c\/li\u003e\n\u003cli\u003e1x 16340 USB-C Rechargeable Lithium Battery\u003c\/li\u003e\n\u003cli\u003e1x USB-C Charging Cable\u003c\/li\u003e\n\u003cli\u003e1x Professional Carabiner Hook\u003c\/li\u003e\n\u003cli\u003e1x Diving Lanyard\u003c\/li\u003e\n\u003cli\u003e3x Spare Watertight O-rings\u003c\/li\u003e\n\u003cli\u003e1x Comprehensive User Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"XSTAR","offers":[{"title":"Default Title","offer_id":57729422131573,"sku":null,"price":32.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/1588\/4738\/files\/XSTARBEACON.png?v=1793895582","url":"https:\/\/www.divealotscuba.co.uk\/products\/x-star-sd1-beacon-4-colour","provider":"Divealot Scuba","version":"1.0","type":"link"}
