Guide TU 3.0 Thermal Scopes
The Guide TU 3.0 series is Guide's main thermal riflescope line, with 400, 640 and 1280 sensors and 35mm, 50mm and 60mm lenses on a 30mm tube. For a lighter 256 option, see the Guide Nova.
S models keep it simple, LS models add a laser rangefinder, and the M and MS MUO models add a 1920×1080 day/night channel. Start with the TU635S 3.0 for 640 detail, the TU650LS 3.0 for ranging at distance, or the TU1260MS MUO 3.0 for the top end.

Reading TU 3.0 model names
- First digits: 4 = 400×300, 6 = 640×512, 12 = 1280×1024.
- Last two digits: the lens, for example 35 = 35mm and 50 = 50mm.
- S / LS / M / MS: S = standard, LS = laser rangefinder, M and MS MUO = multispectral with a day/night channel.
