Guide TJ1250LP LRF

The Guide TJ1250LP LRF sets a new benchmark for handheld thermal optics, delivering exceptional image resolution, precision rangefinding, and robust field performance. At its core lies an ultra-high-resolution 1280 × 1024 VOx sensor with a 12 µm pixel pitch and an ultra-sensitive NETD of ≤ 18 mK, ensuring razor-sharp thermal imaging—even in low-contrast conditions like rain, fog, or cold nights.

Equipped with a premium 50 mm f/1.0 germanium lens, the TJ1250LP LRF captures a generous field of view of 31 × 25 meters at 100 m, giving users expansive situational awareness while maintaining the ability to zoom in on distant subjects. With 2.36× to 37.76× magnification, this monocular enables both wide-area scanning and focused observation of subjects at up to 2,600 m away. For added precision, its integrated laser rangefinder (LRF) provides exact distance measurements up to 1,500 meters.

Visual clarity is ensured by a vivid 0.5″ AMOLED display with an outstanding 1600 × 1200 resolution. The 50 Hz refresh rate offers seamless viewing, while multiple thermal color palettes—including White Hot, Black Hot, Red Hot, Iron Red, and more—help optimize detection across a range of environments. The eyepiece includes 16 mm of eye relief, wide diopter adjustment, and up to 18× digital zoom for precise customization to each user’s vision.

With built-in Wi‑Fi (2.4 G/5 G), Bluetooth, and USB‑C connectivity, the TJ1250LP LRF supports real-time video streaming, firmware updates, and easy content transfers. It records photo and video with audio directly onto its expansive 256 GB internal memory. A microphone, compass, and gyroscope add further functionality, supporting field documentation and navigation.

The device runs on two replaceable 18650 batteries, offering up to 6 hours of continuous runtime. Rugged and reliable, it is housed in a durable IP67-rated chassis, ensuring protection from dust, water, and tough environmental conditions. With intuitive ergonomics and tactical-grade performance, the TJ1250LP LRF is a top-tier tool for advanced thermal users, wildlife professionals, and security personnel.
