What to verify before you order
- Probe diameter versus the opening you will enter.
- Whether you need side views (articulation) or only a centre-line shot.
- Phone connection path (USB-C / Lightning adapter) on the handset you own.
- IP rating for wet work—and which parts are not waterproof.
Honest limits
An endoscope does not measure compression, find every micro-crack, or replace a proper sewer reel. Use it to reduce guessing, then escalate when the job exceeds a phone kit.
EndoscopeHub’s Pro 360° articulating kit (6mm steerable probe, 1080P, IP67 probe, 2m semi-rigid cable) sits at £78.11 with UK-facing support—verify fit to your ports before treating it as a universal tool.
Frequently asked questions
Will a phone endoscope replace a dealer inspection?
No. It is a low-cost visual check for obvious carbon, scoring or moisture—not a compression or leak-down test.
Do I need a special app?
Most wired USB-C kits stream through a simple viewer app. Confirm Lightning/USB-C adapter needs for your phone before the viewing day.
What should I look for on a used engine?
Even deposits, unusual scoring, coolant traces or heavy wet sludge. Photograph anything unclear and walk away if access is blocked.
Is 1080P enough inside a cylinder?
Yes for home screening. Move slowly and brace the cable so the image stays sharp enough to read the walls.
