A plumber pushes the flexible cable around a P-trap to locate a hairline crack without cutting into drywall. An HVAC technician feeds it into a supply duct to confirm whether mold growth has reached the plenum box.

If you're buying it mainly for a car, take the 6.2 mm.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill the picture be clear enough to spot a crack?\u003c\/strong\u003e\u003cbr\u003e\nFor the kind of thing you'd act on — carbon build-up, a scored cylinder wall, a cracked pipe, a blockage, a dropped bolt — yes. Hold the lens about a thumb's length from what you're looking at and turn the LEDs down if the surface is shiny. It is not a metrology instrument; it won't measure a hairline crack for you.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a phone or an app?\u003c\/strong\u003e\u003cbr\u003e\nNo. The H406B has its own screen and its own battery and works straight out of the box. If you'd rather use your phone as the display, the \u003ca href=\"\/en\/products\/ralcam-h406a-iphone-borescope\"\u003eH406A\u003c\/a\u003e does exactly that.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSemi-rigid or flexible cable — what's the difference?\u003c\/strong\u003e\u003cbr\u003e\nSemi-rigid bends and then holds the shape you give it, so you can route it around components in an engine bay and keep the shot steady. Flexible follows existing curves, which suits drains and ducts. The H406B ships with semi-rigid as standard.\u003c\/p\u003e\n\n\u003ch3\u003eUsing it\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe picture is washed out and white — what do I do?\u003c\/strong\u003e\u003cbr\u003e\nTurn the LEDs down. Shiny metal reflects the light straight back into the lens. This fixes nine out of ten \"bad image\" reports.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe lens fogs up or looks hazy.\u003c\/strong\u003e\u003cbr\u003e\nUsually condensation from moving between a cold engine bay and a warm room — give it a minute or two to acclimatise and it clears. If the haze stays, it's residue on the lens: wipe it with a soft cloth. And on a brand-new unit, check you've removed the protective cap from the camera head and the film from the screen.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I put the probe in water, oil or coolant?\u003c\/strong\u003e\u003cbr\u003e\nThe probe, yes — it's IP67. The handset, no. Rinse and wipe the probe afterwards; a cloth lightly dampened with isopropyl alcohol handles oil and grease. Don't use solvents, they attack the lens and the seal.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I get the photos onto my computer?\u003c\/strong\u003e\u003cbr\u003e\nEither pull the microSD card and use a card reader, or connect the handset over USB-C.\u003c\/p\u003e\n\n\u003ch3\u003eShipping and support\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhere does it ship from and how long does it take?\u003c\/strong\u003e\u003cbr\u003e\nFrom our US warehouse.
