The Guide TN650L delivers a 640 × 512 12μm thermal binocular with an integrated 1,500-meter laser rangefinder, 7-hour hot-swap battery, and 128 GB of onboard recording — at $3,799, hundreds below comparable Pulsar Merger LRF XP50 (~$5,200) and iRayUSA Mate MAH50 (~$5,500+) binoculars in the same sensor class. Built on Guide's TN MUO 2.0 platform with a slim, single-handed-focus chassis, it's the entry into integrated-LRF thermal observation without crossing the $4,000 mark.

Key Features

• 640 × 512 @ 12μm thermal sensor with 18mK NETD — full 50 Hz refresh; comparable resolution and noise floor to thermal binoculars selling $1,400+ above this price
• 50mm F1.0 germanium objective with 3.9x–31.2x continuous zoom — base magnification covers most scanning use cases; zoom extends to ID distance
• Integrated 1,500m / 1,630yd laser rangefinder with onboard compass and gyroscope — single-button distance to target plus heading and inclination data
• 0.49" 1920 × 1080 AMOLED display, 20mm eye relief — full-HD imaging with generous eye box
• 2,800-yard man-target detection — pairs the sensor and lens for the longest scanning range in this class
• 7-hour runtime on internal cell + replaceable 18650 — hot-swap design covers a full night of observation; commodity 18650 cells, no proprietary battery
• 128 GB internal storage with audio recording — among the largest onboard storage in this segment; capture observation footage for later review
• Compass + gyroscope — orientation and inclination data on the eyepiece for ranging-with-context
• WiFi (2.4G + 5G), Bluetooth — companion connectivity for app integration and file transfer
• IP67 weather sealing — rain, dew, and dust ingress rated
• Slim binocular housing — Guide's TN MUO 2.0 platform is approximately 20% lighter than the previous generation; 711 g total weight with one-handed silent focus knob
• 58–72 mm interpupillary distance, ±6 diopter adjustment — fits virtually all adult face sizes; per-eye diopter compensates for individual prescription

How It Compares

• vs Pulsar Merger LRF XP50 (~$5,200): same 640-class thermal sensor, integrated LRF, but the Pulsar costs $1,400 more. Pulsar wins on Stream Vision app maturity and accumulated firmware history; the TN650L wins on price, larger onboard storage (128 GB vs 64 GB), and replaceable 18650.
• vs iRayUSA Mate MAH50 (~$5,500–$6,000): comparable 640-class thermal binocular; iRay adds shutterless architecture. TN650L undercuts by $1,700+ at similar core spec, with the trade-off being shutter calibration vs Guide's mechanical shutter design.
• vs AGM Voyage LRF (~$3,000–$3,500): closer on price but uses a 384 × 288 sensor — meaningfully lower resolution. The TN650L brings 640 × 512 at the same price tier.

Ideal For

• Predator and varmint hunters scanning open ground at night — the 3.9x base magnification and 8.2° × 5.0° FOV cover the typical scanning envelope, and the integrated LRF removes the second-device handoff
• Big-game scouts and outfitters working pre-dawn and post-dusk — the 7-hour battery covers a full setup-to-pull-out window without battery juggling
• Livestock guards monitoring herds and predator pressure — the binocular form factor fits naturally on a chest harness; the LRF and compass help log predator approach distances
• Buyers stepping up from monocular thermal — the binocular form factor reduces eye strain over long observation sessions and improves depth perception in the field

Accessories & Compatibility

• Ships with eye mask, neck strap, soft carry bag, 18650 battery + charger, USB cable, quick start guide, and warranty card
• WiFi connection supports companion app pairing for media transfer and ballistics integration
• 10-year manufacturer warranty backed by Guide's US-based repair center in Texas
