Borescopes

Match the probe diameter and insertion length to the spaces you need to access, choose a camera resolution and illumination level suited to the detail required, and decide between wired or wireless models and monitor size based on portability and image-sharing needs

Higher camera resolution (720p/1080p or greater) gives clearer images for diagnostics, adjustable LEDs help in dark cavities, and steerable or articulated tips improve the ability to view around bends versus fixed probes

Check for ingress protection (IP) ratings for water and dust resistance, reinforced or braided probe sheaths for abrasion resistance, and temperature or chemical resistance specifications if you'll inspect hot, oily, or corrosive environments

Many borescopes offer onboard storage (microSD), USB, Wi‑Fi, or HDMI outputs and support common file formats (JPEG, MP4) so you can save, transfer, and review media on phones, tablets, or computers

Entry-level inspection cameras for occasional home use can be found under $100, mid-range units with better optics and articulation commonly fall in the $100–$300 band, while industrial-grade systems with high resolution, long probes, and rugged housings are typically higher

Clean the probe and tip after each use with appropriate solvents or wipes, dry thoroughly, store coils loosely to avoid kinking, check seals and cables for damage, and follow manufacturer guidelines for replacing worn tips or batteries

Many borescopes are versatile for different trades, but ensure the probe diameter, length, temperature tolerance, and camera features match the specific requirements of automotive engines, HVAC ducts, or plumbing lines before relying on one device for all tasks
