Most thermal riflescopes under $1,500 cut corners — 17μm sensor pitch, polymer housing, no ballistics integration. The Guide Nova N435 doesn't. A 400 × 300 12μm sensor with 20mK NETD in a magnesium alloy chassis, paired with the TargetIR Ballistics app and a 1,950-yard detection range, puts the N435 ahead of polymer-bodied ATN ThOR LTV scopes at the same price and on equal footing with the AGM Rattler V2 35-384 (~$1,795) at $300 less.

Key Features

• 400 × 300 @ 12μm sensor with 20mK NETD — finer pixel pitch than 17μm 384-class competitors; sharper edges on hot signatures, lower noise in low-thermal-contrast scenes
• 35mm F1.0 germanium lens, 3.3x – 13.2x optical magnification — covers close-range identification through 200+ yard target work; 7.9° × 5.9° field of view (13 × 10 m at 100 m)
• 1,800m / 1,950yd man-target detection — pairs the sensor and lens for the longest detection in the Nova series
• 0.39" 1024 × 768 AMOLED display, 48mm eye relief — generous eye box for offhand and prone shooting
• TargetIR Ballistics app — Bluetooth pairing for ballistic profiles, calibers, and trajectory calculation; Guide's app maintains a regularly updated database for common calibers and manufacturers
• Recoil-triggered auto-recording — captures a 15-second video plus 5 photos automatically when the rifle fires; review POI without fumbling for a record button
• Magnesium alloy housing — at the $1,500 price point most competitors use polymer; magnesium is lighter, stiffer, and holds zero better through temperature swings
• IP67 weather sealing — rain, dew, and dust ingress rated
• 7.5-hour runtime with hot-swap external 18500 — built-in custom cell powers short bursts, replaceable 18500 (×2 included) extends to a full night; 20W fast charging supported
• 6,000J shock rating — manufacturer's published mechanical durability spec
• WiFi (2.4G + 5G), Bluetooth, 32 GB internal storage — onboard photo/video recording with audio
• Seven image palettes — White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, Sepia

Ideal For

• Predator and varmint hunters working open fields, food plots, and fence lines from 50 to 250+ yards — the 35mm lens and 3.3x base magnification cover the classic predator hunting envelope without sacrificing close-quarters acquisition
• Hunters who want app-driven ballistics — the TargetIR ballistics database and trajectory calculator simplify holdovers in the field; pair once, profile your rifle, hunt with confidence
• Mid-budget thermal buyers stepping up from a polymer ATN ThOR LTV — the magnesium chassis, finer sensor pitch, and 10-year US warranty are the meaningful upgrade at this price
• Hunters who shoot first and review later — the auto-record-on-recoil feature captures the shot for review and training, no thumb-fumbling required

Accessories & Compatibility

• Quick-release scope mount included in the box — ships ready to install on standard Picatinny rails; no additional mounting hardware needed for most setups
• Pair the TargetIR Ballistics app via Bluetooth to load your rifle's ballistic profile, then view holdover and wind drift solutions on the eyepiece in the field
• Ships with two 18500 batteries, charger, USB-C to USB-C cable, lens cover, eye mask, quick-release scope mount, quick start guide, and warranty card
• 10-year manufacturer warranty backed by Guide's US-based repair center in Texas
