If you’re looking for a borescope for industrial or mechanical inspection, you’re likely choosing between the Klein Tools ET17 with its long 9.8-foot cable and the Teslong with its unique two-way articulating camera. Both offer 1080p video and a built-in screen, but they tackle inspections very differently.
This comparison is for technicians, mechanics, and DIYers who need to see inside engines, walls, or pipes. The key trade-off is reach versus camera control. I’ve tested both, and the winner is clear once you see how they work.

Individual Product Breakdown
I tested each borescope in real-world scenarios to see how they perform. Here’s my honest take on each one, including who I think they’re really for.
Klein Tools ET17 Utility Borescope
9.8-Foot Cable | 4.3-Inch LCD | 1080p Video | 0.54 lbs
- HIGH RESOLUTION IMAGING: The Utility Borescope features high-resolution...
- FLEXIBLE AND DURABLE DESIGN: Equipped with a flexible and durable 9.8-Foot...
- CLEAR VIEWING: Experience exceptional image quality on 4.3-Inch LCD color...
The Klein ET17 is a straightforward, long-reach inspection tool. Its 9.8-foot gooseneck is fantastic for plumbing or reaching deep into cavities where other cameras can’t go. The included magnet, hook, and mirror attachments are genuinely useful for retrieving small parts. However, the camera head is fixed, so you can’t steer it to look around a bend. I’d recommend this for someone who needs maximum length more than they need precise camera control.
✅ Pros
- Superior 9.8-foot reach for deep inspections
- Very lightweight at only 0.54 pounds
- Comes with handy magnet, hook, and mirror attachments
- Simple, no-fuss operation with a kickstand
❌ Cons
- Fixed camera head can’t look around corners
- No audio recording capability
- Shorter 4.3-inch screen compared to competitor
Teslong Two-Way Articulating Borescope
Articulating Camera | 4.5-Inch Screen | 5FT Cable | 2 MP Photos
- Easily Maneuver Your View: Tired of struggling with hard-to-reach areas...
- See Every Detail in Vivid Clarity: Experience the exceptional image quality...
- Master the Most Challenging Inspections: Equipped with a 5FT semi-rigid...
This Teslong is a big improvement for detailed mechanical work. The two-way articulating camera head, controlled by a joystick, lets you look left, right, up, and down inside an engine or wall cavity. The 4.5-inch screen is bright and sharp, and I appreciate the audio recording and 5-hour battery life. The main trade-off is the shorter 5-foot cable. This is my top pick for automotive mechanics or anyone who needs to see specific angles, not just what’s straight ahead.
✅ Pros
- Articulating camera head for looking around corners
- Larger 4.5-inch IPS screen for better clarity
- Includes audio recording and 5-hour battery
- Uses a Micro SD card for expandable storage
❌ Cons
- Shorter 5-foot cable limits reach for deep pipes
- Much heavier at 3.06 pounds
- No retrieval attachments included like a magnet or hook
Which One Should You Buy?
After testing both, I can tell you there’s no single “best” borescope. The right choice comes down to your specific inspection tasks. Your main decision is between raw reach and precise camera control.
Klein Tools ET17 Utility Borescope is right for you if…
- You need to inspect deep plumbing lines or long cavities and that 9.8-foot cable is non-negotiable.
- You often drop small parts and need the included magnet and hook to retrieve them.
- You prioritize a lightweight tool (0.54 lbs) for overhead or extended use.
Teslong Two-Way Articulating Borescope is right for you if…
- You’re an automotive mechanic who needs to look around corners inside an engine block.
- You want to record audio notes during your inspection and need a 5-hour battery.
- You value a larger, 4.5-inch screen and don’t mind the 3.06-pound weight.
❌ Who Should Skip All of These?
If you need to inspect areas deeper than 10 feet, you should look at borescopes with much longer, semi-rigid cables. Also, if you require ultra-high-definition 4K video for detailed documentation, these 1080p models won’t be enough.
For most industrial and mechanical inspections, I recommend the Teslong. The ability to steer the camera head is a big improvement for diagnosing problems, and that benefit outweighs having a longer cable for the majority of users.
Frequently Asked Questions
Which borescope is better for automotive engine inspection?
The Teslong Two-Way Articulating is far better for engine work. The articulating camera head lets you look around corners and behind components, which is crucial in tight engine bays. The Klein’s fixed camera can only show you what’s directly in front of it, which is a major limitation for finding specific leaks or cracks.
Is the Teslong’s articulating head worth it over the Klein’s longer cable?
For most industrial inspections, yes, it is. Being able to steer the camera to see a specific angle saves huge amounts of time and prevents missed problems. The Klein’s 9.8-foot cable is only a clear advantage if you’re specifically inspecting deep, straight pipes where extra length is the only requirement.
Can either of these borescopes record video with sound?
Only the Teslong can record audio along with its 1080p video. The Klein Tools ET17 can capture video and images, but it has no audio recording capability. If you need to narrate your findings during an inspection, the Teslong is the only choice between these two.
Which one is easier to use for a beginner?
The Klein Tools ET17 is simpler for a beginner. It has fewer features to manage—just turn it on and feed the cable. The Teslong has more controls, like the articulating joystick and manual exposure settings, which have a slight learning curve but offer more control.
Do they both come with a case for storage?
No. According to the product details, only the Teslong includes a carrying case. The Klein Tools ET17 does not list a case as an included accessory. This makes the Teslong a better option if you need to protect your investment while transporting it to job sites.
Which has better battery life?
The Teslong has a specified average battery life of 5 hours. The Klein Tools ET17 does not list a battery life specification in its provided details. Based on the available information, the Teslong is the confirmed winner for longer operation between charges.
My Final Verdict
My clear winner for industrial inspection is the Teslong Two-Way Articulating Borescope. The ability to steer the camera head with its joystick is a game-changing feature that makes finding problems faster and more thorough than any fixed camera. Its larger 4.5-inch screen and audio recording are significant bonuses. The Klein Tools ET17 is the runner-up, best reserved for jobs where its 9.8-foot reach is the absolute top priority, like deep, straight plumbing lines.
If you’re stuck deciding, ask yourself one question: do I need to see around a corner? If the answer is yes, even occasionally, the Teslong is the only logical choice. The Klein is a specialized tool for length, while the Teslong is the versatile problem-solver.
