The CB-400 Cobra-4 borescope (photo) features a dual head blue- and white-light LED (light-emitting diode) to allow technicians to inspect and check for leaks in hard-to-see components without disassembly. The blue LED is designed for fluorescent leak detection while the white light is ideal for component inspection. The Cobra-4’s shaft is 4-mm wide and 36-in. long, and it comes with an angled inspection mirror and three AAA alkaline batteries. — Spectronics Corp., Westbury, N.Y.
