DNT Optics TNC335R ThermNight — Thermal & Night Vision Multi-Spectral Scope with Laser Rangefinder & Ballistic Calculator

The TNC335R ThermNight is the step-up model in DNT Optics’ fusion scope range — a 384×288 thermal channel paired with a 1920×1080 Sony STARVIS 2 night vision channel that doubles as a genuine day/colour channel in good light. Switch between them with one button, or run Picture-in-Picture to see thermal detection and a clear digital image side by side. A 1,100-yard laser rangefinder, DNT’s ballistic engine with digital gyroscope, and one-shot zeroing on both channels round it out — one optic that works from daylight through to full dark.

Key features

• Dual-sensor fusion: A 384×288 thermal channel (35mm lens, 2.5x base, 2.5–10x digital) alongside a 1920×1080 Sony STARVIS 2 channel (5x base, 5–20x digital) that works as both a night vision and a daylight/colour channel.
• Picture-in-Picture (PIP) mode: View thermal detection and the clear digital channel in the same frame — spot the heat signature, then confirm what it is.
• Works day and night: The Sony STARVIS 2 channel isn’t limited to low light — it delivers a genuine colour image in daylight too, so the same scope covers a still hunt at dusk and a follow-up look the next morning.
• Integrated laser rangefinder: Class 3R eye-safe, ranging out to 1,100 yards.
• Built-in ballistic calculator with digital gyroscope: DNT’s ballistic engine gives dial-in or holdover solutions, with cant and inclination correction from the onboard gyroscope.
• Thermal Zoom Lock: Keeps your zoom level consistent on the thermal channel as you switch magnification, so you don’t lose your target while adjusting.
• One-shot zeroing on both channels: Zero the thermal and night vision channels independently, each holding its own zero.
• 8 reticle styles in 5 colours: Pick the reticle and colour that stands out best against your background.
• 1920×1080 Micro-OLED display: Shared by both channels, at 60Hz — a step up from the entry TNC225R’s 1024×768 panel.
• WiFi enabled with DNT app support: Stream, review and manage footage from your phone.
• Built-in 64GB memory: Double the onboard storage of the TNC225R.
• 800Gs shock rating and IP67 waterproofing: Built to handle heavy recoil and keep working through rain, dust and mud.

One scope, day into night

Most thermal/night vision combo scopes are still built around the dark. The TNC335R’s second channel is a genuine daylight-capable colour sensor as well as a low-light one, so you can glass a paddock in full colour in the afternoon, watch the light fade, and switch to thermal or PIP once it’s properly dark — all on the same scope, without swapping optics.

384×288 thermal, refined

The thermal channel steps up from the TNC225R’s 256×192 sensor to a sharper 384×288, with ≤18mK thermal sensitivity for a cleaner, more detailed heat picture at range.

Who it’s for

Built for hunters who want one scope that covers the whole day, not just the dark hours — daylight colour viewing, a proper night vision channel, thermal detection, and PIP fusion when you need both at once. The sharper 384×288 thermal sensor and larger 64GB memory make it a genuine step up from the TNC225R for anyone shooting more serious sessions or covering longer range.
