Spectronics Corp. introduced the CB-400 COBRA-4, part of the COBRA series of multi-purpose borescopes. This scope features a dual-head blue and white light LED flashlight that enables aviation technicians to inspect and leak check hard-to-see components without expensive disassembly, according to company officials.
The blue-light LED is for fluorescent leak detection, while the white-light LED is for component inspection. A press-fit coupler allows quick and easy attachment of the flashlight to the borescope. The COBRA-4 has a thin 4mm water- and abrasive-resistant 36 inch (91.4 cm) shaft to get into crammed areas.
Included with the scope is a clip-on, angled inspection mirror, which provides the added capability to detect flaws normally hidden from view. Three AAA alkaline batteries (included) power the flashlight. Fluorescence-enhancing glasses, for use with the blue light flashlight and fluorescent leak detection dyes, are also included. Dyes are sold separately. All components are packed in a plastic carrying case with a foam insert.
