Guide Usa Thermal Riflescope Tu425 Se3.0 400X300

The Guide USA Thermal Riflescope TU425 SE3.0 is a 400x300 uncooled thermal scope built for serious hunters, tactical shooters, and predator callers who need to see in complete darkness. Unlike traditional night vision, this thermal riflescope detects heat signatures rather than ambient light, so it performs equally well on moonless nights, in fog, rain, and heavy brush. The 25mm objective lens and 3.1x to 12.4x magnification range give you flexibility from close-range hunting to extended detection work at 1,400 yards.

The TU425 runs on a dual battery system—a rechargeable internal battery (USB-C) paired with an external 18650 slot—giving you up to 12 hours of continuous operation and redundancy in the field. Its shutterless design means no image freezing or mechanical noise between shots, a real advantage when hunting game that reacts to sound. The 0.49-inch AMOLED 1920×1080 display is sharp and responsive, with multiple color palettes (white hot, black hot, red hot, and more) so you can choose what works best in your hunting scenario. Dual-band WiFi and Bluetooth let you review recordings and adjust settings from your phone, while the integrated 32GB recorder captures photo and video with audio—useful for documenting successful hunts or reviewing what you've seen.

Built tough with an IP68 waterproof rating and a 6000J shock rating that handles .300 Win Mag recoil, this scope is sealed against the elements and dependable in serious use. The 48mm eye relief and -5 to +5 diopter adjustment accommodate most shooter preferences, and the standard 30mm tube diameter fits common rifle platforms. At 575 grams and compact dimensions, it balances capability with manageable weight on a hunting rifle.

Frequently Asked Questions

What's included with the TU425 SE3.0?

The scope ships with a quick-release scope mount, carry bag, two 18650 batteries, a 5V/2A battery charger (region-specific adapter), USB-A to USB-C cable, lens cover, eye mask, quick start guide, and warranty card. Optional add-ons include a Bluetooth remote control and laser rangefinder module.

Can I use this thermal scope in rain or fog?

Yes. Thermal scopes detect heat signatures rather than reflected light, so they work in fog, rain, snow, and complete darkness where traditional optics and night vision fail. The TU425 is rated IP68 waterproof, so it handles wet conditions reliably.

What rifle platforms does the 30mm tube fit?

The standard 30mm tube diameter fits the vast majority of modern rifle mounts and rings designed for 30mm scope tubes. Verify your rifle's scope base before purchase, but most hunting and tactical AR-platform and bolt-action rifles accept 30mm optics.

How long will the batteries last in the field?

The dual battery system provides up to 12 hours of continuous operation. You can swap the external 18650 in the field or recharge the internal battery via USB-C at camp. Carrying spare 18650 batteries is a practical way to extend runtime on extended hunts.
