Frequently Asked Questions

The CEBAR D2S is a precision digital fire-control scope engineered for military, law enforcement, and professional long-range applications. Unlike conventional optical scopes, the D2S integrates a full sensor suite - including a laser rangefinder, GPS receiver, gyroscopic sensors, onboard weather station, and a ballistic computation engine - into a single compact system. It displays a 4K+ OLED image with a customisable digital reticle and automatically calculates real-time trajectory corrections based on environmental and positional data. It is designed and manufactured by CEBAR Industries, based in Abu Dhabi, UAE.

The D2S is available in three configurations, each designed for a different operational range requirement:

• Minimum engagement distance across all variants: 25 metres
• All variants support calibres from 5.45mm to 20mm

The D2S combines an integrated sensor suite that feeds real-time data into its onboard ballistic computer:

• Laser rangefinder - instant, precise target distance measurement
• GPS receiver - positional data for location-aware ballistic correction
• Gyroscopic sensor - measures cant angle and platform movement
• Onboard weather station - captures live temperature, atmospheric pressure, and humidity
• Ballistic computation engine - fuses all sensor inputs to calculate real-time trajectory corrections

All data is overlaid directly on the 4K+ OLED display with a customisable digital reticle, removing the need for separate ballistic calculators or external devices.

The D2S delivers 40+ hours of active operational battery life, making it suitable for extended field deployments without requiring a battery change or recharge. This high endurance is designed specifically for military and law enforcement operations where sustained, uninterrupted performance is critical. Exact battery life may vary depending on display brightness settings, sensor polling frequency, and ambient temperature conditions.

The D2S is engineered to operate reliably across a full military-grade temperature range of -40°C to +80°C (-40°F to +176°F). This covers Arctic and sub-zero environments as well as extreme desert or tropical heat - ensuring operational readiness regardless of geographic or seasonal conditions. The thermal resilience of the system reflects CEBAR's focus on defence and professional-grade use cases where environmental extremes are routine.

The D2S is compatible with a broad calibre range from 5.45mm to 20mm, encompassing standard infantry rifle calibres, sniper and anti-materiel rifle rounds, and heavy machine gun calibres. This wide compatibility makes the D2S suitable for a diverse range of platforms - from designated marksman rifles (DMRs) through to large-bore precision rifles - without requiring a separate fire-control system for each weapon type. Platform-specific configuration and reticle profiles can be adjusted through the ballistic computer interface.

A traditional optical scope magnifies a target image through a glass lens system; the shooter must manually account for range, wind, temperature, and cant. The CEBAR D2S replaces this entirely with a digital fire-control platform. Key differences include:

• A 4K+ OLED display instead of an optical eyepiece - zero degradation at maximum zoom
• Automated ballistic computation that calculates corrections in real time rather than requiring manual estimation
• An integrated rangefinder and weather station - eliminating the need for separate ancillary devices
• A fully customisable digital reticle that adapts to calibre, range, and conditions
• GPS integration for position-aware targeting data

The result is a system where the shooter receives a corrected firing solution rather than raw optical data - reducing the cognitive load at the point of engagement.

The D2S is designed and manufactured by CEBAR Industries, a precision optics and defence technology company headquartered in Abu Dhabi, UAE. CEBAR draws on a foundation of German ballistic analysis expertise combined with UAE-based engineering, innovation, and ISO-certified production. The company's product portfolio extends beyond the D2S to include the Spectronight digital night vision system and the EB-MK ONE professional ballistic radar.

Yes. The D2S is purpose-built for military, law enforcement, and professional precision applications. Its design specification - military-grade temperature range, 40+ hour battery endurance, broad calibre compatibility, and real-time fire-control computation - addresses the operational requirements of defence and security procurement. CEBAR Industries supplies and supports institutional customers directly. For procurement enquiries, volume orders, or technical evaluation requests, contact CEBAR through the official website at cebar-industries.com or email info@cebar-industries.com.

No. The D2S is a fully self-contained fire-control system. All ballistic computation, environmental sensing, range finding, and positional tracking are performed internally by the onboard systems. There is no requirement for a separate rangefinder, ballistic app, wind meter, or GPS unit. This all-in-one architecture reduces the operator's equipment load and eliminates the inter-device latency and compatibility issues associated with managing multiple separate tools in the field. Calibre profiles and user preferences are configured directly through the D2S interface.

Spectronight is a professional digital night vision brand developed by CEBAR Industries, based in Abu Dhabi, UAE. The Spectronight product line uses advanced BSI CMOS (Back-Side Illuminated CMOS) sensor technology to deliver high-definition visual performance in near-zero light conditions - without relying on traditional image intensifier tube (IIT) technology. Spectronight systems are designed for military, law enforcement, security, surveillance, and professional field operations, and are supplied to users across the USA, Canada, Europe, and Australasia. The brand name reflects its core purpose: capturing the full spectrum of available light - from near-zero starlight through to infrared wavelengths - across the operational domain of darkness.

Spectronight systems use BSI CMOS (Back-Side Illuminated Complementary Metal-Oxide Semiconductor) sensors - the same generation of imaging architecture that transformed professional photography and broadcast cinematography, now applied to tactical and professional night observation. In BSI sensors, the light-sensitive circuitry is positioned behind the photodiode layer rather than in front of it, allowing significantly more light to reach each pixel. This delivers superior low-light sensitivity, greater dynamic range, and higher image resolution compared to conventional front-side illuminated sensors - and eliminates the fragility, bulk, and white-flash vulnerability inherent to image intensifier tube (IIT) systems.

Spectronight systems achieve a minimum light sensitivity of 0.0001 lux - a performance level classified as dark starlight. To put this in context, a moonless overcast night typically measures around 0.001 lux; Spectronight sensors operate a full order of magnitude below this threshold. This means the system delivers usable, high-definition imagery in conditions that are effectively pitch-black to the naked eye, with no active illumination required.

Fusion sight is a night vision capability that combines digital low-light imaging and infrared imaging into a single, unified visual output. Rather than presenting one channel at a time - as tube-based systems do - a fusion sight overlays both data streams simultaneously, giving the operator a composite picture that captures both fine visible-spectrum detail and thermal contrast in the same view. This significantly improves target detection, identification, and situational awareness in complex or visually ambiguous environments.

Yes - select Spectronight D2L fusion models include this capability. The fusion sight architecture is one of the primary differentiators between Spectronight's advanced variants and conventional single-channel night vision systems. Tube-based systems cannot offer fusion sight by design, as they depend on a single image intensifier channel.

Conventional night vision has used image intensifier tube (IIT) technology for over 60 years, amplifying available light photon-by-photon through a vacuum chamber. Spectronight replaces this with solid-state BSI CMOS digital imaging. Key differences:

Yes. Spectronight devices support both HD video recording and real-time wireless streaming to iOS and Android devices. This enables operators to capture footage directly from the device for evidence, documentation, or after-action review - and to stream a live feed to a command device or secondary observer without requiring a physical connection. These capabilities are not available on traditional image intensifier tube systems, which are purely optical in architecture and cannot output a digital signal. Wireless streaming makes Spectronight particularly effective for team-based surveillance, tactical coordination, and remote monitoring applications.

Spectronight systems offer a 50° field of view (FOV). This wide-angle field of view is a meaningful tactical advantage over many tube-based night vision devices, which typically offer narrower FOVs due to the physical constraints of image intensifier tube optics. A wider FOV increases situational awareness, reduces the "tunnel vision" effect common to older night vision technology, and allows operators to scan environments more naturally without constantly repositioning the device.

Yes. Spectronight devices are rated to IP67, meaning they are fully dustproof and protected against immersion in water up to 1 metre depth for up to 30 minutes. IP67 certification ensures reliable operation in rain, high humidity, river crossings, and dusty or sandy environments - conditions routinely encountered in military, law enforcement, and outdoor professional applications. This all-weather rating is a standard expectation for professional-grade night vision equipment operating in the field.

Spectronight is purpose-built for professional and institutional users who require reliable, high-performance night vision across demanding operational environments. Primary user groups include:

• Military units - infantry, special operations, surveillance and reconnaissance
• Law enforcement agencies - tactical units, border protection, and surveillance teams
• Security and protection professionals - perimeter security, critical infrastructure monitoring
• Professional hunters and field operators - requiring legal, high-performance low-light optics

Spectronight products are supplied to users across the USA, Canada, Europe, and Australasia. For procurement or evaluation enquiries, contact CEBAR Industries directly at info@cebar-industries.com.

Spectronight is the dedicated night vision brand of CEBAR Industries - a precision optics and defence technology company headquartered in Abu Dhabi, UAE. CEBAR develops, engineers, and manufactures the full Spectronight product range in-house, drawing on a team of international specialists in optics, digital imaging, sensor technology, and software. Spectronight sits alongside the D2S digital fire-control scope and the EB-MK ONE professional ballistic radar as part of CEBAR's broader portfolio of precision optical systems.

The EB-MK ONE is a professional radar-based ballistic analyser that measures projectile velocity, trajectory, drag behaviour, and flight characteristics at high precision - going far beyond what a standard chronograph can capture. It uses 24GHz K-Band continuous wave Doppler radar sampling at up to 20 million measurements per second to track projectiles in real time and generate detailed ballistic data including full downrange velocity profiles, drag coefficients, tumble, self-rotation, flight angle, and energy. The EB-MK ONE is built on German radar engineering from Evo-Ballistix and is distributed as part of the CEBAR Industries precision optics and ballistics ecosystem. It is designed for ammunition manufacturers, weapon manufacturers, defence programs, precision shooters, ballistic researchers, and forensic teams who require measured data, not estimates.

A chronograph measures muzzle velocity at a single point - typically 1-2 metres from the muzzle - and nothing else. The EB-MK ONE is a fundamentally different class of instrument. It captures full downrange velocity decay, drag behaviour, tumble, self-rotation, flight angle, and energy throughout the projectile's flight path, not just at the muzzle.

This makes the EB-MK ONE the appropriate tool for any application where measured performance data - not estimated BC values - is required.

The EB-MK ONE captures a comprehensive set of ballistic parameters per shot:

All environmental conditions - temperature, pressure, humidity - are captured by the onboard weather station and automatically factored into the ballistic calculations.

A G1 or G7 Ballistic Coefficient (BC) is a single number that describes how well a projectile retains velocity compared to a standardised reference projectile. BCs are derived from manufacturer test conditions and represent an average - they do not account for the specific drag behaviour of your projectile at different velocities, with your barrel, in your conditions.

A measured drag profile (Custom Drag Model / CD curve) captures actual velocity decay data at multiple points across the projectile's flight, producing a complete picture of how drag changes with speed for that specific round under real conditions. This is what the EB-MK ONE generates.

At extended ranges - beyond 600m - the divergence between BC estimates and measured drag profiles becomes significant. A measured drag profile produces more accurate ballistic predictions at long range, which is why it is the preferred method for ammunition validation, defence acceptance testing, and precision long-range load development.

The EB-MK ONE is a professional instrument designed for users who require verified, measured ballistic data rather than estimates. Primary user groups include:

• Ammunition manufacturers - production lot validation, QA testing, acceptance certification, and consistency analysis across production runs
• Weapon manufacturers - weapon-ammunition matching, test condition documentation, and performance certification for new platforms
• Defence procurement programmes - independently verified ballistic data for ammunition acceptance and weapons system qualification
• Precision shooters and long-range teams - measured load data for custom drag profile development and drop table generation at extreme ranges
• Ballistic research institutions - raw Doppler radar data access, spectral analysis, and fundamental projectile flight research
• Forensic teams - documented shot data with full environmental and technical metadata per shot

The EB-MK ONE integrates directly with the D2S digital fire-control scope's ballistic computation engine. Measured drag profile data generated by the EB-MK ONE can be exported and loaded into the D2S, replacing the generic manufacturer BC estimates that the scope would otherwise use with measured drag coefficients specific to the ammunition being used.

The practical effect is a significant improvement in first-round hit probability at extended ranges. Instead of the D2S calculating trajectory based on a published BC average - which may not reflect the actual performance of that production lot in field conditions - it calculates using data measured from the actual rounds being fired. This is the operational benefit of the full CEBAR ecosystem: the EB-MK ONE generates the data; the D2S applies it.

The EB-MK ONE uses 24GHz K-Band continuous wave (CW) Doppler radar, transmitting at up to 100mW within the highest safety regulations. Continuous wave radar allows a far greater sampling density, enabling the EB-MK ONE to achieve up to 20 million measurements per second. At this resolution, the system can detect subtle signal variations that reveal not just velocity but also projectile spin, tumble, and even smaller particles at the muzzle exit event via spectral analysis.

Velocity precision is ±0.24 m/s at any speed. The frequency is adjustable between 24.000-24.250GHz in 50MHz steps - with 9 sub-channels per step - allowing multiple EB-MK ONE units to operate simultaneously on the same range without signal interference.

The EB-MK ONE is designed for rapid, no-software-installation deployment. Setup to first shot typically takes under 5 minutes.

• Interface: Browser-based UI - accessed via any smartphone, tablet, or PC. No software installation required. Compatible with all major browsers
• Connectivity: WiFi (2.4GHz) or LAN cable. No internet connection required - the EB-MK ONE runs its own onboard web server
• Positioning: 5-50cm behind and 10-40cm to the side of the muzzle at muzzle height. Can also be positioned downrange for mid-flight velocity measurement
• Triggers: Microphone (sound) or radar-based - allowing use with suppressors, subsonic ammunition, and on busy ranges
• Battery: Custom battery pack providing 6-8 hours of operation
• Weight / size: 2.5kg (5 lbs), 25×20×10cm with battery attached. Tripod-mountable
• Data export: All shot data exports to .CSV, compatible with Excel, Google Sheets, and ballistic software

Evo-Ballistix is the German radar engineering company behind the core technology of the EB-MK ONE. Based in Germany, Evo-Ballistix specialises in radar-based ballistic measurement and analysis, and developed the EB-MK ONE as an advanced trajectory analytics instrument for professional ballistic research.

CEBAR Industries, headquartered in Abu Dhabi, UAE, integrates the EB-MK ONE into its broader precision optics and ballistics ecosystem - alongside the D2S digital fire-control scope and the Spectronight night vision system. CEBAR distributes the EB-MK ONE internationally and provides the direct integration pathway between EB-MK ONE measured data and the D2S ballistic computation engine. For procurement enquiries, contact CEBAR at info@cebar-industries.com.

The EB-MK ONE is available to qualified buyers globally, including ammunition manufacturers, defence procurement programmes, weapon manufacturers, precision shooting teams, and ballistic research institutions in the USA, Canada, Europe, Australasia, and the Middle East. There are two routes to procurement:

• Via CEBAR Industries - for buyers requiring D2S integration, Middle East supply, or the full CEBAR precision ecosystem: info@cebar-industries.com
• Via Evo-Ballistix directly - for technical documentation, EXPERT software licensing, and European supply: info@evo-ballistix.de

The EB-MK ONE does not calculate BC directly - it measures something more fundamental: velocity at every point along the flight path. From that continuous velocity decay curve, the ballistic coefficient (and more usefully, the full drag profile) can be derived mathematically. The process works in three steps:

• Step 1 - Measure velocity over distance. The radar records muzzle velocity, then tracks the Doppler-shifted return signal as the bullet decelerates downrange, logging velocity at continuous intervals
• Step 2 - Compare against drag models. The observed deceleration curve is compared against standard drag models (G1, G7, or custom Cd curves) to determine aerodynamic efficiency relative to a reference standard
• Step 3 - Generate the drag profile. Rather than producing a single BC number, the system generates a velocity-dependent drag curve - showing exactly how drag changes as the bullet decelerates from supersonic through transonic and into subsonic flight. This is what gets imported into the D2S

A standard G1 or G7 BC is a single averaged number - it describes how a bullet behaves relative to a standardised reference at an average velocity. The problem is that drag is not constant: it changes significantly as a bullet transitions through different velocity regimes.

• Supersonic (above ~340 m/s): Drag is dominated by wave drag - the bullet is pushing a shockwave ahead of it. Drag coefficient is relatively stable but high
• Transonic (~280-380 m/s): The bullet is crossing the sound barrier. Drag becomes highly unpredictable and non-linear - this is where single BC values diverge most significantly from reality
• Subsonic (below ~280 m/s): Wave drag disappears. Drag is lower and more stable, but the bullet's behaviour has fundamentally changed

A single BC averaged across all these regimes is accurate at medium range - but at extreme range (beyond 600-800m), where a bullet is transitioning between regimes, the error compounds. The EB-MK ONE's custom drag model captures the full Cd(Mach) curve, giving the D2S accurate drag data at every velocity - not an average.

Yes. Because the EB-MK ONE samples the returning radar signal at up to 20 million times per second, it captures subtle variations in the Doppler return that reveal projectile behaviour beyond velocity alone. A perfectly stable bullet produces a clean, consistent Doppler return. A tumbling bullet produces additional signal components at frequencies corresponding to its rotation or wobble, identifiable via spectral analysis.

Practical applications include:

• Detecting weapon-ammunition incompatibility (barrel twist rate vs. bullet weight/length)
• Identifying damaged or deformed projectiles in a production batch
• Diagnosing accuracy problems that are projectile-stability rather than shooter-technique related
• Forensic identification of irregular projectile behaviour in incident reconstruction

The EB-MK ONE uses continuous-wave (CW) Doppler radar, which transmits a constant signal rather than sending pulses. This is a deliberate technical choice:

The EB-MK ONE occupies a distinct professional tier - above consumer-grade Doppler devices, and significantly below the price and complexity of military instrumentation radars:

The EB-MK ONE's strategic differentiator is not just its measurement capability - it is the direct data pipeline into the D2S fire-control scope, which no competing professional radar offers.

The confirmed integration pathway is from EB-MK ONE measured data into the D2S ballistic computation engine - replacing static BC estimates with live measured drag profiles specific to the ammunition in use. This is a documented, production-ready capability.

Broader integration with external battlefield management systems (BMS) or networked targeting platforms is architecturally plausible given the system's browser-based interface, LAN/WiFi connectivity, and CSV data export. However, specific BMS integration protocols have not been publicly disclosed.

Defence procurement officers evaluating the EB-MK ONE for systems integration should contact CEBAR Industries directly to discuss technical interface requirements: info@cebar-industries.com.

The EB-MK ONE contains an internal environmental measurement station that captures atmospheric conditions at the moment of each shot:

Together these determine density altitude - the effective air density at the shooting location. When the data is imported into the D2S, the scope receives environmentally compensated drag data, not data from a manufacturer's test chamber in different conditions.

The EB-MK ONE EXPERT is optional Windows software that unlocks advanced analysis capabilities beyond the standard browser-based interface. It is designed for users who need to go deeper into the raw radar data rather than simply reading measurement outputs.

• Raw Doppler signal display - view the raw radar return waveform to detect irregular bullet behaviour not visible in processed velocity data
• Spectral analysis - decompose the raw signal to differentiate main projectile from secondary objects (gas, particles, sabot petals) or identify tumble signatures
• Custom drag profile editor - build and adjust true Cd(Mach) drag curves from measurement data, and convert between CD profiles and multi-BC tables
• Rate-of-fire analysis - full shot-by-shot breakdown of automatic weapon bursts up to 2.4 seconds in length
• Recalculation engine - reprocess any stored raw shot file with different environmental conditions, drag functions, or positioning assumptions
• Offline mode - analyse previously downloaded data without connection to the hardware
