GSCI TI GEAR C345, 45mm

• 1x clip-on thermal design: The TI GEAR C345 mounts in front of a daytime optic, adding thermal capability without changing the familiar handling of the rifle or forcing a separate dedicated thermal sight setup.
• 384x288 sensor with 17 μm pixel pitch: This sensor format delivers clear thermal contrast for target detection and observation while keeping the unit compact enough for practical clip-on use.
• 45 mm F1.1 objective and 2030.00 m detection range: The fast lens gathers more thermal energy, helping the device detect heat signatures at long distance and improving image usefulness in difficult weather and low-contrast scenes.
• 800x600 AMOLED display with 50.00 Hz refresh rate: A high-resolution display and smooth refresh make scanning, tracking and shot execution more natural, especially when targets are moving.
• Rugged all-weather construction: Waterproof, fogproof and shockproof construction, together with operation from -40℃ / +50℃, supports field use in rain, cold, heat and rough transport conditions.

About the GSCI TI-GEAR-C Series

The GSCI TI-GEAR-C series is built as a thermal imaging clip-on sight for users who want to add thermal capability to a daytime riflescope instead of replacing their existing optic. In GSCI’s lineup, this series serves professional aiming, reconnaissance and tactical surveillance roles, combining thermal detection with the familiar sight picture and ergonomics of a day optic. That approach is especially useful when a rifle is already set up around a preferred daytime scope and the user wants thermal performance with minimal change to the platform.

A defining characteristic of the series is its silent sensor with Auto-NUC, which helps maintain image consistency while reducing distraction during observation. GSCI also equips the TI-GEAR-C family with an 800x600 AMOLED display and shared 2x and 4x digital zoom options, giving the series a practical balance between image detail and flexible target assessment. The range includes several objective lens sizes and sensor configurations, allowing the platform to cover different priorities, from compact handling to longer-range detection. GSCI lists the series as dustproof and waterproof, and offers on-rail and scope-mounted attachment options, reinforcing the TI-GEAR-C family’s role as a field-oriented thermal solution for users who need a clip-on system rather than a standalone thermal sight.

About the GSCI TI GEAR C345, 45mm

The GSCI TI GEAR C345, 45mm is the more compact 45 mm version in the TI-GEAR-C family, pairing a 384x288 thermal sensor with a 45.00 mm F 1.1 objective in a 1x clip-on format. In practice, that makes it well suited to rifles already equipped with a daytime optic, where the goal is to add thermal detection without changing the rifle’s established sighting setup. The 1.00x optical presentation is important in a clip-on device because it preserves compatibility with the day scope behind it, while the available digital zoom settings extend observation capability when more target detail is needed.

The sensor uses a 17.00 μm pixel pitch, a 50.00 Hz refresh rate and 50.00 mK sensitivity. Together, these characteristics help the unit present moving heat signatures smoothly and separate subtle temperature differences more clearly, which matters when animals, people or equipment do not stand out strongly from the background. The stated 2030.00 m detection range gives the C345 useful reach for surveillance and target detection, while the 800x600 AMOLED display provides a crisp viewing image with good apparent contrast.

At 183.00 mm in length and 545.00 g in weight, the TI GEAR C345 remains manageable on a rifle without adding the bulk of a larger clip-on. Its waterproof, fogproof, shockproof and rubberized construction supports hard field use, and the operating range of -40℃ / +50℃ suits demanding climates. Power comes from CR123 batteries with up to 7.00 h of runtime, giving the unit practical endurance for extended observation periods or a full outing in the field.

About GSCI

GSCI, short for General Starlight Company Inc., was founded in 1992 in Toronto as an OEM for night-vision systems. The company is based in Vaughan, Ontario, and focuses on electro-optical equipment for professional use. Its core expertise covers night-vision, thermal-imaging and fusion systems, along with related laser rangefinders and accessories, which places the brand firmly in the field of tactical and observation optics rather than conventional sporting optics alone.

Over time, GSCI expanded from night vision into more advanced thermal and fused imaging platforms. The company introduced thermal-imaging goggles in 2002, followed by its first Fusion goggles in 2006 and an electronic Fusion night-vision system in 2009. GSCI’s fusion technology was patented in 2013, reflecting a long-term emphasis on integrating multiple imaging methods into practical field devices. That background is directly relevant to the TI-GEAR-C series, which draws on the company’s experience in rugged thermal systems designed for surveillance, aiming and professional operational use.
