Inspection Tools: FAQ

How do I choose the right probe diameter for automotive use?

Ensure the probe diameter fits your specific spark plug or drainage hole. Most automotive tasks require a 5.5mm or 8mm probe for optimal clearance and maneuverability.

How can I verify the image quality before buying?

Look for 1080p resolution and adjustable LED brightness in the product description. High-quality sensors provide clear visuals even in dark, oily environments common in car repair.

What specs indicate a durable inspection tool?

Check for an IP67 or IP68 waterproof rating and a semi-rigid cable. These features ensure the tool survives contact with automotive fluids and maintains its shape during use.

Will the integrated screen models arrive safely?

Most reputable sellers use reinforced foam packaging for integrated screen models. Choose 'AliExpress Selection Standard' shipping for better handling and more reliable tracking.

Recommendations for buyers

✓
Sensor Resolution
Prioritize 1080p HD resolution to ensure you can identify fine cracks or carbon buildup without pixelation.

Cable Rigidity
Select semi-rigid cables that can be bent into shape and hold their position, which is essential for vertical inspections.
✓
Illumination Standards
Look for tools with at least 6-8 adjustable LED lights to prevent glare on metallic surfaces while providing sufficient brightness.
✓
Battery Capacity
For standalone units, look for at least 2000mAh to ensure 3-4 hours of continuous diagnostic work without recharging.
