Borescopes For Dummies

The right tool makes all the difference in the field, especially when you need to inspect tight spaces quickly, efficiently, and without costly disassembly. That’s where borescopes come in. These inspection tools allow professionals across industries—automotive, aviation, manufacturing, HVAC, and more—to get a clear view of internal components without dismantling machinery.

Whether diagnosing engine issues, inspecting industrial equipment, or troubleshooting a plumbing system, understanding borescopes is essential for selecting the right one. This guide breaks down the different types of borescopes, key features to consider, and how to choose the best model for your specific needs.

What is a Borescope?

A borescope is a specialized inspection tool that allows users to see inside confined spaces without disassembling machinery or components. It consists of a long, thin probe with a camera and light source at the tip, transmitting real-time visuals to a display screen.

Common Uses for Borescopes

• Automotive diagnostics – Inspecting cylinders, valves, and fuel injectors.
• Manufacturing quality control – Checking welds, castings, and other hard-to-reach areas.
• Aviation maintenance – Inspecting turbine engines and aircraft components.
• Plumbing & HVAC – Detecting blockages, leaks, and corrosion in pipes and ducts.
• Security & Law Enforcement – Tactical inspections and forensic investigations.

Types of Borescopes

Different jobs require different tools. Borescopes come in various designs, each suited for specific applications.

1. Rigid Borescopes

• Best for straight-line inspections.
• Delivers high-quality images with no flexibility.
• Commonly used in manufacturing and precision engineering.

2. Articulating Borescopes

• Offers controlled movement (up, down, left, right) for a full inspection view.
• Useful for aviation, automotive, and industrial applications requiring maneuverability.
• Available in manual and motorized articulation options.

3. Videoscopes

• Equipped with a built-in digital camera for high-resolution imaging.
• Offers real-time video and image recording capabilities.
• Best for modern automotive and industrial inspections.

4. USB & Wireless Borescopes

• Connects to smartphones, tablets, or computers.
• Affordable and portable for quick inspections.
• Great for DIY mechanics and general maintenance.

Key Features to Consider When Buying a Borescope

Choosing the right borescope depends on your specific needs. Here are some factors and advice to keep in mind:

1. Camera Resolution & Image Quality

• Higher resolution means clearer images. For industrial work, opt for at least 720p HD, though 1080p or higher is best for precision inspections.

2. Probe Length & Diameter

• Length: Ranges from a few inches to over 30 feet. Choose based on the inspection depth required.
• Diameter: Smaller probes can access tighter spaces; common sizes include 2mm, 4mm, 6mm, and 8mm.
• Diameter matters—smaller probes (under 6mm) fit into tight engine spaces.

3. Articulation & Flexibility

• Non-articulating: Fixed direction.
• 2-way articulation: Moves up and down.
• 4-way articulation: Moves in all directions for full maneuverability.
• Useful for turbine engine inspections, HVAC systems, and complex machinery.

4. Lighting Options

• LED lighting: Standard and energy-efficient. It is essential for dark spaces.
• Adjustable brightness: Helps in dark or reflective areas. Prevents glare and enhances visibility.

5. Durability & Waterproofing

• Look for IP67+ rated borescopes for water and dust resistance.
• Durable construction for industrial environments.

6. Connectivity & Data Storage

• Wi-Fi, USB, or Bluetooth for easy data transfer and real-time sharing of images and video.
• SD card slots or internal storage (32GB or more recommended) ensure inspection data can be recorded and saved.

7. Battery Life & Portability

• Longer battery life ensures uninterrupted inspections. Look for models with four or more hours of usage per charge. It is ideal for field use.
• Compact, lightweight designs for easy handling in the field.

Best Uses for Borescopes in Different Industries

Automotive Inspections

• Check for carbon buildup in cylinders.
• Inspect turbochargers and exhaust systems.

Manufacturing & Quality Control

• Detects cracks, defects, and poor welds in machinery.
• Inspect small components without disassembly.

 Chemical Processing

• Inspect reactors, pipes, and vessels for corrosion or buildup
• Detect internal issues in pumps or valves
• Monitor the condition of pressure vessels

Oil & Gas

• Inspect valves, pumps, and compressors
• Check internal components of drilling rigs
• Monitor pipelines for leaks or corrosion

Aviation & Aerospace

• Examine turbine engines and jet components.
• Ensure aircraft safety compliance.

HVAC & Plumbing

• Identify pipe blockages and corrosion.
• Inspect air ducts and ventilation systems.

Law Enforcement & Security

• Tactical inspections in hazardous environments.
• Surveillance and forensic evidence collection.

Borescope Maintenance & Best Practices

To extend the lifespan of your borescope:

• Clean the lens and probe after each use.
• Store in a protective case to prevent damage.
• Avoid forcing the probe into tight spaces to prevent breakage.
• Keep software and firmware updated for best performance.
