The TOPDON VIS002 Borescope features a 5.5 mm probe with 210-degree two-way articulation for inspecting engine cylinders, intake ports, and other confined spaces. Its 1 MP HD camera and eight adjustable LEDs provide visibility of defects such as carbon buildup, cracks, corrosion, and leaks. A built-in 4.3" IPS display shows images without requiring a smartphone or app. The IP67-rated probe resists dust and water exposure. Photo and video recording, a 32GB microSD card, and included magnet and hook attachments support documentation and parts retrieval.
