GSCI Unitec B75 Thermal Imaging Binocular

• 75 mm F1.3 objective lens: the large aperture gathers more thermal energy, which helps the binocular maintain stronger image brightness and target definition at long observation distances and in difficult weather.
• 640x480 thermal sensor with 17 μm pixel pitch: this sensor format gives the UNITEC B75 enough native detail for scanning, identifying heat sources, and following movement without relying immediately on digital zoom.
• Dual AMOLED displays: a separate display for each eye supports more natural binocular viewing, reduces eye strain during extended surveillance, and improves comfort compared with single-eye observation.
• 4.5x to 18x total magnification: the combination of base magnification and digital zoom lets the binocular cover both wide-area observation and closer target assessment from a fixed position.
• Aluminum housing with IPX-6 protection: the robust body, fogproof construction, and wide operating temperature range support dependable use in rain, cold, and demanding field conditions.

About the GSCI Unitec Series

The GSCI Unitec series is built as a family of thermal imaging observation systems for users who need dual-eye viewing for reconnaissance and tactical surveillance. Within GSCI’s thermal lineup, the series covers both thermal binoculars and helmet-mountable thermal goggles, giving professional users a choice between dedicated handheld observation and hands-free use. The range includes models with 17-micron and 12-micron thermal sensors, while selected configurations are offered with 9 Hz or 50 Hz refresh rates and 2x or 4x digital zoom.

A defining characteristic of the series is its dual AMOLED display layout, which gives each eye its own display for a more natural viewing experience during long periods of observation. In practical use, that matters when operators need to scan terrain, monitor movement, and stay on glass for extended sessions without the fatigue that often comes with monocular devices. Across the series, GSCI positions Unitec models for medium- to long-range surveillance, with an emphasis on rugged construction, dependable thermal performance, and controls suited to professional field work rather than casual use.

About the GSCI Unitec B75 Thermal Imaging Binocular

The GSCI Unitec B75 Thermal Imaging Binocular is the long-range configuration in the Unitec binocular family, combining a 75.00 mm objective lens with a 640x480 ASi uncooled thermal sensor and a stated 3000.00 m detection range. That combination makes it well suited to observation tasks where the priority is early heat-source detection at distance rather than the widest possible field of view. The 5.00 ° field of view keeps the image focused on distant terrain features, while the 87.00 m/1000m view still gives enough scene coverage for deliberate scanning from a hide, vehicle, or fixed observation point.

Its 4.50 x base magnification provides useful native reach before digital enlargement is applied, and the system extends to 18.00 x maximum magnification when closer inspection is needed. In practice, this helps the user move from broad thermal detection to more careful assessment without changing devices. The 50.00 Hz refresh rate supports smoother tracking of moving subjects, while the 60.00 mK NETD contributes to usable thermal contrast when temperature differences in the scene are modest.

Comfort and durability are equally important here. The binocular uses dual 800x600 AMOLED displays for two-eye viewing, which is easier to stay behind for long sessions than a single-eyepiece thermal. A 20.00 mm eye relief helps with viewing comfort, and the aluminium housing, IPX-6 waterproofing, fogproof construction, and -40 ° / + 50° C operating range make the B75 appropriate for hard outdoor use. Power comes from AA batteries, with up to 8.00 h battery life, and tripod adaptability adds stability for long surveillance periods.

About GSCI

GSCI, short for General Starlight Company Inc., was founded in Toronto in 1992 as an OEM for night-vision systems. The company is a Canadian electro-optical manufacturer based in Vaughan, Ontario, and it focuses on night-vision, thermal-imaging, and fusion systems for professional use. Its product range includes night-vision monoculars and goggles, thermal-imaging devices, laser rangefinders, and related accessories.

GSCI introduced thermal-imaging goggles in 2002, followed by its first Fusion goggles in 2006 and an electronic Fusion night-vision system in 2009. The company’s fusion technology was patented in 2013, reflecting its long involvement in combining multiple imaging channels for demanding operational environments. In the thermal and night-vision category, GSCI is known for building robust observation systems with a strong emphasis on field durability, dual-eye viewing solutions, and electro-optical platforms intended for military, law-enforcement, and other professional applications.
