The Guide TB 2.0 is a hunting-focused thermal clip-on that turns your existing day scope into a thermal sight — keep your trusted reticle and zero, and add thermal in front of it.
The TB650S has the same 640×512 detector and 50 mm F0.9 lens as the TB650LS, without the rangefinder. Expect up to 2600 m detection range, around 5 hours of operation and IP68 weather sealing — thermal capability without replacing the day scope you already trust.

Key Features
- G-Zero shutterless – no calibration freeze at start-up or during use, so the image stays live behind your day-scope reticle.
- Hyper-Light algorithm – fine detail, low noise and strong contrast at distance.
- Ready for day scopes up to 15× – 1.22 cm @ 100 m adjustment for precise alignment with your day optic.
- LRF in lens (L models) – the rangefinder sits on the objective axis for accurate ranging without extra bulk.
- 6000 J recoil rating – minimal point-of-impact shift under repeated centrefire recoil.
- Standard 18650 batteries – easy-to-source cells shared with other Guide devices; carry spares and swap in the field.
- Virtual reticle recording – recorded video shows a reticle overlay, with an on-device album for instant playback.
Best For
- Adding thermal to a quality day scope you already shoot well

Frequently Asked Questions
How does the Guide TB650S compare with the rest of the TB 2.0 range?
The TB 2.0 line-up: TB650P 2.0 (640×512, 50 mm lens, 2600 m detection, 1500 m rangefinder); TB650 2.0 (640×512, 50 mm lens, 2600 m detection); TB1260LS (1280×1024, 60 mm lens, 3200 m detection, 1200 m rangefinder); TB650LS (640×512, 50 mm lens, 2600 m detection, 1200 m rangefinder); TB650S (640×512, 50 mm lens, 2600 m detection). Larger lenses see further but give a narrower field of view; 640×512 detectors show more detail than 400×300 at the same distance.
How far can the TB650S see?
Guide rates the TB650S at 2600 m detection — the distance at which a large-animal-sized heat source shows on screen. Recognising what the animal is happens closer than that, and rain, fog and high humidity all shorten thermal range.
What do I need to fit it to my scope?
A clip-on attaches to the objective end of your day scope with an adaptor ring sized to the scope's outer objective diameter. Guide clip-on adaptor rings (sold separately) cover 38–64 mm objective bells — see the adaptor rings. Check your point of impact after fitting.
How long does the battery last?
Guide quotes around 5 hours of operation. Battery: 1 × replaceable 18650 battery.
Does it connect to a phone?
Yes. It connects over Wi-Fi to Guide's TargetIR app to stream live view, download photos and video, and update firmware.
Can I use a thermal device for hunting in Australia?
Rules on thermal and night-vision equipment differ between states and between public and private land. Check your state's hunting and firearms regulations, and the conditions of any permit or property access, before using it in the field.
