Teslong NTG100H-C features a 26" rigid stainless steel probe with laser-etched depth markings every inch — the only Teslong borescope with precision depth positioning. The rigid probe stays precisely where you put it, unlike flexible scopes. The depth markings and rubber positioning ring let you return to the exact same spot during cleaning cycles. The 6-mirror set covers .20 & Larger caliber: five 45° mirrors (5/6/7/8.5/10mm) plus a 5mm 35° anti-glare mirror. Dual-connection: USB-C for iPhone/Android, USB-A for Windows/Mac. Free app from official app store. Six adjustable LEDs with brightness dial. Waterproof probe, stainless steel shaft, braided USB cables. Foam-lined case. Choose NTG100H-C (rigid) for repeatable positioning; NTG100-C (flexible 45") for full muzzle-to-chamber reach.

• 6 Adjustable LEDs with Brightness Dial: Dim for polished bores, bright for deep chambers. The adjustable light reduces glare, revealing carbon and copper deposits that are invisible under fixed lighting. Side mirror adjusts for different calibers.
• Waterproof, Corrosion-Resistant & Portable: Waterproof probe for easy cleaning. Stainless steel shaft resists corrosion. Braided USB cables. Foam-lined case. For gunsmiths, precision shooters, and firearm owners who want exact barrel condition data.
