Guide TB1260LS HD Thermal Clip-On with 1,200m Laser Rangefinder

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. The TB1260LS brings 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 per frame of a 640 × 512 sensor, so the 60mm lens covers a wide 14.6° field at 0.2 mrad per pixel
• 60mm F1.0 lens — a 14.6° × 11.0° field of view (25 × 19 m at 100 m); the longer focal length gives a narrower field and more reach than a 50mm lens on the same sensor
• 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
• 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 for long-range observation
• 6,000 J shock rating — the manufacturer's published mechanical durability spec
• IP68 sealing — rated against dust ingress and prolonged immersion
• 6-hour runtime on 2× replaceable 18650 batteries — commodity cells you can replace in the field; no proprietary pack to charge or replace
• WiFi (2.4G + 5G), Bluetooth, 64 GB internal storage — 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; Guide built it palm-sized and balanced for mounting ahead of a day scope

Why HD Resolution Matters

A 640 × 512 sensor behind a 50mm lens covers 8.8° at about 0.24 mrad per pixel. The TB1260LS's 1,280 × 1,024 grid behind its 60mm lens covers 14.6°, about 66% wider, at 0.2 mrad per pixel, so it scans more ground with finer detail. At long range that detail is what separates shape, posture and animal size, the cues that tell a hog from a deer or a domestic dog. 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 at long range
• Precision rifle shooters running 6.5 PRC, .300 PRC, or larger — 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 TB650LS or competing 640 clip-on once budget and use case justify the resolution jump

Accessories & Compatibility

• Bell-mount adapter for objective installation — the TB1260LS mounts on the host scope's objective with Guide's adapter rings: A for 38–46 mm, B for 48–54 mm and C for 56–64 mm objectives. Guide's clip-on ring mount and quick-release scope mount are optional. Measure your host scope's objective bell diameter and order the matching 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.
• 5-year manufacturer warranty (10 years on the thermal sensor) backed by Guide's US-based repair center in Texas.
