See in the Dark: OSelect – TS004 Thermal Imaging Monocular
If you’re looking to boost your visibility in the dark, the OSelect – TS004 Thermal Imaging Monocular could be the tool for you. Whether you’re spending nights in the bush, monitoring property, or observing wildlife, this monocular offers a practical way to see what the eye can’t.
With sharp 256×192 IR resolution, a swift 50Hz refresh rate, and a robust 5000mAh battery, the TS004 blends strong performance with handy features like live wireless monitoring—all in a rugged, waterproof body made for Australian conditions.

Why a Thermal Imaging Monocular is Useful
Thermal monoculars deliver clear vision regardless of lighting conditions by picking up heat signatures. The TS004 stands out by providing vivid thermal images and a detection range of up to 410 metres. This means you can spot animals, people, or obstacles at night and through fog or thick undergrowth—a distinct advantage over traditional torches or night vision gear.
Who Should Consider the TS004?
- Outdoor enthusiasts – Hikers, campers, and 4WD drivers who want to see wildlife or navigate after dark.
- Property and security managers – Monitor larger properties, sheds, or livestock even in poor visibility.
- Boaties and rescue volunteers – Quick identification of people or hazards on water at night.
- Hunters and nature observers – Quiet nighttime spotting without extra lighting.
This device isn’t just for professionals; even weekend adventurers will benefit from its clarity and durability.
