The Guide TB1260LS delivers a 1,280 × 1,024 thermal sensor, 15 mK NETD, and an integrated 1,200m laser rangefinder behind a 60mm F1.0 lens — a configuration without a direct retail competitor at this price. iRay's 1,280-class clip-ons aren't shipping yet, Pulsar's Krypton 2 line tops out at 640, and N-Vision's rumored 1,280 clip-on is reportedly $10,000+. At $5,699 the TB1260LS is the entry point for HD thermal clip-on capability with onboard ranging — built on Guide's new ApexVision S1 architecture with G-Zero Shutterless Design and AI Hyper-Light image processing.

Key Features

• 1,280 × 1,024 @ 12μm sensor with 15 mK NETD — four times the pixels-on-target of a 640 × 512 sensor and meaningfully lower noise; resolves a 36-inch target at ~1,000 yards into 40+ pixels of usable detail
• 60mm F1.0 germanium lens — wider native field of view (14.6° × 11.0°, 25 × 19 m at 100 m) than 50mm 1,280-class clip-ons; gathers more thermal energy at maximum range
• 3,200m / 3,500yd man-target detection — pairs the HD sensor with the larger lens for the longest detection in the TB lineup
• Integrated 1,200m / 1,300yd laser rangefinder — onboard ranging at the host scope eyepiece; no second device, no second battery to manage
• 0.5" 1,600 × 1,200 AMOLED display, 20mm eye relief — larger and higher-pixel-density eyepiece than typical clip-on AMOLEDs
• G-Zero Shutterless Design — Guide's architecture eliminates startup image freezing during shutter calibration, so target tracking is uninterrupted at the moment of acquisition
• AI Hyper-Light algorithm — high-sensitivity detector + AI processing for sharper details, lower noise, and optimized contrast in rain, fog, and dewpoint conditions
• 6,000 J shock rating — the manufacturer's published mechanical durability spec
• Magnesium alloy chassis, IP68 — over 20% lighter than comparable 1,280-class housings (manufacturer claim); rated against dust ingress and prolonged immersion
• 6-hour runtime on 2× replaceable 18650 batteries — commodity cells, hot-swap mid-hunt; no proprietary pack to charge or replace
• WiFi (2.4G + 5G), Bluetooth, 64 GB internal storage — full-HD photo and video recording with audio capture
• Seven image palettes — White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, Sepia
• 740g / 26.10 oz — heavier than 640-class clip-ons but among the lightest 1,280-class units in market

How It Compares

• vs Guide TB1250 LRF Pro (the 50mm predecessor at ~$5,549): the TB1260LS upgrades the platform with a 60mm lens (vs 50mm), tightens NETD from 18 mK to 15 mK, adds the ApexVision G-Zero shutterless architecture and Hyper-Light AI, and steps up to a 0.5" 1,600 × 1,200 display. The Gen 2 jump is more than a refresh — different sensor pipeline, different mechanical platform.
• vs N-Vision rumored 1,280 clip-on (reportedly $10,000+, not yet shipping): reserved for institutional buyers; the TB1260LS delivers 1,280-class capability at roughly half the rumored street price.
• vs Pulsar Krypton 2 / iRayUSA RICO Mk1 / AGM Rattler-C V2 (all 640-class at $3K–$4K): the TB1260LS is a category up — 4× the pixels per frame, integrated 1,200m LRF, larger display, larger lens. The right comparison for hunters who specifically need HD identification at 800+ yards.

Why HD Resolution Matters

A 640 × 512 sensor at 1,000 yards puts roughly 20 pixels on a 36-inch target — enough for detection but rarely enough for identification (hog vs deer vs domestic dog). The TB1260LS's 1,280 × 1,024 grid resolves the same target into 40+ pixels — the threshold where shape, posture, and animal size become distinguishable. For predator hunters who shoot to ID, livestock guards working with mixed wildlife near domestic animals, or institutional users who must positively identify before committing, HD resolution is the gating spec, not a nice-to-have.

Ideal For

• Long-range predator hunters at 500–1,000+ yards where 640-class identification breaks down — the 1,280 × 1,024 sensor and 60mm lens combine to keep targets resolvable past detection range
• Precision rifle shooters running 6.5 PRC, .300 PRC, or larger — the magnesium chassis preserves zero on the host scope, and the integrated 1,200m LRF removes the second-device handoff in the field
• Hunters who require positive HD identification before committing — livestock guards, mixed-game scenarios, professional outfitters who shoot under accountability
• Buyers stepping up from 640-class — the TB1260LS is the natural upgrade path from a TB650LP or competing 640 clip-on once budget and use case justify the resolution jump

Accessories & Compatibility

• Bell-mount adapter for objective installation — the TB1260LS uses Guide's GARTA bell-mount system rather than a hardmounted Picatinny base. A Picatinny adapter is available separately for rail-mounted setups. Verify your host scope's objective bell diameter (50mm, 56mm, etc.) and order the matching adapter ring.
• Pairs with SFP and FFP daylight rifle scopes. For SFP scopes, zero at the magnification you'll hunt at — clip-on misalignment with the host scope amplifies linearly with magnification.
• Ships with carry bag, accessory bag, lint-free cloth, two 18650 batteries, charger, USB-A to USB-C cable, quick start guide, and warranty card.
• 10-year manufacturer warranty backed by Guide's US-based repair center in Texas.
