Night Pearl Marten 420

• Conventional riflescope form: The Night Pearl Marten 420 uses a familiar scope-style layout, so it mounts and handles more like a traditional hunting optic than a compact thermal viewer.
• 400x300 VOx sensor: Its 400x300 thermal core with 17.00 μm pixel pitch gives a clear heat signature for spotting animals and reading movement in changing night conditions.
• 50 Hz refresh rate: A 50.00 Hz refresh rate keeps motion looking smoother, which helps when tracking moving game and panning across wider terrain.
• OLED display with onboard recording: The 1024×768 OLED screen presents a crisp viewing image, while photo and video recording let the user document sightings and review shots later.
• Field-ready runtime and durability: With up to 10.00 h of battery life plus waterproof, fogproof and shockproof construction, the scope is built for long sessions in difficult weather.

About the Night Pearl Marten Series

The Night Pearl Marten series was introduced in 2022 as a family of thermal riflescopes built in a conventional day-scope style. Within Night Pearl’s lineup, the Marten models sit as dedicated thermal sights for hunters who want a familiar mounting and shooting format rather than a handheld or clip-on device. The series was developed through a collaboration between Night Pearl and Guide, and it was aimed at hunting in varied field conditions.

Named variants in the line include the 420, 430, 450, 620 and 630. The Marten 420, 430 and 450 models use 400×300-pixel, 17-micron ceramic VOx sensors, balancing practical detection capability with a straightforward thermal riflescope layout. Across the series, the emphasis is on thermal target acquisition, simple operation and a form factor that feels natural on a rifle. Night Pearl positioned the Marten family for users moving into thermal hunting optics who still wanted the handling of a traditional scope. The series later gave way to the HH range as production focus shifted, which also makes Marten models a distinct part of Night Pearl’s earlier dedicated thermal riflescope offering.

About the Night Pearl Marten 420

The Night Pearl Marten 420 is a dedicated thermal riflescope configured for hunters who prioritize quick target detection at moderate distances and a wide viewing image. Its fixed 1.60 x optical magnification keeps the sight picture easy to acquire, while the 25.00 mm objective and broad 15.49 ° field of view help the shooter scan woodland edges, fields and feeding areas without feeling overly zoomed in. With a stated 700.00 m detection range, it is built to reveal heat sources well before the user is ready to identify and engage them.

The thermal core uses a 400x300 VOx Ceramic sensor with 17.00 μm pixel pitch and a 50.00 Hz refresh rate. In practice, that means a stable thermal image with smoother motion when following moving animals or sweeping across terrain. The 1024×768 OLED display gives the user a clear viewing screen, and the illuminated multi-reticle system with 4 reticle options allows the sight to be set up for different preferences and shooting styles.

For field use, the Marten 420 combines thermal observation and shot documentation in one unit through image capture, video recording and WiFi connectivity. Its 930.00 g body and 367.00 mm length suit a full-size rifle setup, while the 10.00 h battery life supports longer evening hunts without frequent battery changes. Waterproof, fogproof and shockproof construction, together with an operating range of -20°C to +55°C, makes it suitable for regular use in cold mornings, damp weather and rough transport between stands or vehicles.

About Night Pearl

Night Pearl was established in the Czech Republic in 2009, following completion of its first device, the NP-22 night-vision clip-on, in 2008. The company has focused on electro-optics for hunting and observation, with a product range that includes thermal imaging, night vision, digital night vision and daytime optics. Within thermal equipment, its lineup covers handheld devices, clip-ons and rifle scopes, while its night-vision range also extends to monoculars, binoculars, adapters and sights.

A key step in the company’s development came in 2016, when Night Pearl opened a research, development and manufacturing facility in Bystřice pod Hostýnem. That background is relevant to products such as the Marten 420, because it reflects the brand’s emphasis on designing and producing dedicated field optics rather than offering only rebranded accessories. More recently, Night Pearl USA began operating in Sarasota, Florida, in 2023, expanding the brand’s presence and support structure for the American market.
