4-Way Articulating Endoscope – Ralcam M6X | 5" IPS Screen

Rigid tubes hold a fixed shape and push straight into an opening — best for shallow, in-line inspections. Semi-rigid cables bend and hold the shape you give them, so you can route around obstacles and it stays put — ideal for engine bays. Flexible cables follow gravity and existing curves, best for drains and ducts. Ralcam offers all three across the 6.2mm and 8.5mm ranges.

Ralcam probes come in 3.9mm, 5.5mm, 6.2mm and 8.5mm. 6.2mm is the all-round standard with the brightest image. For diesel engine glow-plug and injector bores, choose 6.2mm or smaller; for gasoline car spark-plug holes an 8.5mm probe also fits. Use 3.9–5.5mm for the narrowest bores and 8.5mm when you want a larger, brighter view and the opening allows it. Measure your smallest access hole before ordering.

IP67 means the probe and cable are fully dust-tight and can be briefly submerged in water (up to 1m). That lets you work in wet ducts, drains, coolant lines and oil-filled cavities. It's rated for brief immersion, not prolonged soaking — don't leave the probe underwater for long periods. Important: the rating covers the insertion tube and camera head only — keep the display screen and handle dry.

Ralcam borescopes use HD cameras with adjustable focus for sharp, detailed images. The exact sensor resolution varies by model and is listed in each product's specifications on its page.

The camera head has built-in LED lights (typically six) arranged around the lens, and the brightness is adjustable — so you can light up a dark cavity without washing out the image on shiny or reflective surfaces.

The wide-angle lens gives a broad field of view with a fixed focus optimized for close-range inspection (roughly a few centimetres in front of the tip). See each product page for its exact viewing angle and focal range.

Yes. Models with a built-in screen capture photos and video directly to a TF/microSD card (up to 32GB); you can then transfer files with a card reader or over USB. Phone-connected models save to your phone through the companion app.

The probe is built for mechanical inspection, not sustained heat — always inspect engines and machinery once they have cooled. Brief contact with warm surfaces is fine; avoid inserting into running-hot components. See each product page for its rated temperature range.

Standalone screen models have a built-in rechargeable battery (up to about 6 hours of continuous use on models like the F606B) and recharge over USB. Some models, such as the N5, use a replaceable 18650 cell that is also rechargeable — so you can recharge it in place or swap in a charged spare for all-day work.

Screen models record to a TF/microSD card up to 32GB. Whether a card is included in the box is noted on each product page; if it isn't, any standard card up to 32GB will work.

Articulation means the camera tip bends on command, so you can look around corners instead of only straight ahead. 2-way models steer the tip in one plane (you rotate the probe body to reach any angle); 4-way models add a thumb joystick for full 360° control. It is what lets you inspect cylinder walls, valves and turbine internals.

Some models do. Those with a probe-lock button — such as the N5 and the N3 series (N306/N308) — hold the tip at the angle you set, so you can line up and take a steady photo hands-free. On models without a lock, you simply hold the articulation while shooting.

Gently wipe the camera head with a soft, lint-free cloth. For oil, grease, or debris from automotive or plumbing inspections, use a cloth lightly dampened with isopropyl alcohol or mild soapy water, then dry it before storing. Avoid abrasive materials or harsh solvents, which can scratch the lens or damage the waterproof seal.

On several models the probe is detachable, so a damaged probe can be swapped instead of replacing the whole tool — for example the H406B, M506, F606B and F606A.

Fogging usually happens when the probe moves between temperatures, such as from a cold engine bay into a warm room. Let the device acclimate for a minute or two and it will clear on its own. Persistent haze is almost always residue on the lens—clean it with a soft cloth, and make sure any protective film has been removed from the camera head.

Before first use, draw the probe out of its coil slowly and evenly to avoid kinking the cable, then remove the protective cap from the camera lens. On screen models, also peel the protective film off the display.

The M6X is a premium 4-way articulating scope with a large 5-inch IPS screen, joystick control and a detachable probe — built for demanding auto-repair and industrial work where a bigger, sharper display and precise 360° steering save time on complex inspections.

Both give full 4-way articulation. Choose the M6X for its larger 5-inch IPS screen and detachable-probe build; choose the F606B for a more compact 4-way scope at a lower price. Both suit engine and turbine inspection.
