Teslong TD500 6.5mm Articulating Borescope with Dual Lens Endoscope

I recently purchased the Articulating Borescope with Dual Lens Endo, and it has quickly become one of the most useful inspection tools I own. The build quality feels solid and professional, and the articulating camera design makes it much easier to inspect hard-to-reach areas compared to standard borescopes. The controls are intuitive, and the device feels durable enough for regular use in automotive, mechanical, and household inspections. The dual-lens feature is especially helpful because it allows both forward and side viewing without needing to reposition the camera constantly. This makes inspections faster and more efficient, particularly when checking inside engines, pipes, HVAC systems, or tight wall spaces. The image quality is surprisingly clear, with sharp detail and good color accuracy even in darker environments. One of the standout features is the articulating tip, which provides excellent maneuverability in confined spaces. Being able to bend and direct the camera precisely where needed makes a huge difference when inspecting complex areas. It allows for much more thorough inspections and helps identify issues that would otherwise be difficult to see. The built-in LED lighting works very well and provides enough brightness for most situations. The adjustable light levels are useful because they help reduce glare on reflective surfaces while still illuminating dark spaces effectively. Combined with the high-resolution display, it becomes easy to spot cracks, leaks, corrosion, or loose components. Battery life has also been impressive. I was able to complete several inspections on a single charge without worrying about the device shutting down. The screen is bright and easy to read, and the menu system is straightforward, making the overall user experience smooth and convenient. Another feature I appreciate is how portable and easy to store the unit is. The included accessories and protective case help keep everything organized and protected during transport. The probe cable feels flexible yet sturdy, which adds confidence when navigating through narrow or curved spaces. Overall, the Articulating Borescope with Dual Lens Endo is an excellent inspection tool that delivers strong performance, clear imaging, and outstanding flexibility. It is extremely useful for automotive work, home maintenance, industrial inspections, and DIY projects. I would highly recommend it to anyone who needs a reliable and versatile borescope for detailed inspections in difficult-to-access areas.

As a professional auto tech, this thing is the best. Ive had it over 2 years and it will still beat out the major name brands for 1/4 of the price. The articulating thing works awesome to check valves and see coolant intrusion. I will definitely buy another one, everyone in the shop wants one.

FANTASTIC borescope! The Articulating Borescope Model TD500 in 6.5mm with front + side view cameras works great! I really really liked all the beware statements - bent or over-coiled and operating temperature. I ESPECIALLY liked the big warning sticker around the probe cable. All that helps remind me to be more careful b/c I'm clumsy. The 2 add-ons - the hook and magnet - included in the package fit the 6.5mm probe end great, just be careful unscrewing the bore end (very narrow band around the front camera). I really thought about the 3.9mm borescope model but the user manual stated those add-ons do not work with 3.9mm scope, so choose your diameter wisely. The 2 cameras model is very helpful - front + side-view AND you can switch between either front + side + combined(split front+side) picture on screen! Great product, exactly as described, very maneuverable, great price for a great quality product on my budget, great picture, and shipped next day!

For the price when on sale its a decent product. I like the dual view and the articulating head. The articulation could be a little less resistant feeling. But it works and gets the job done. Make sure you find and get the smallest diameter line possible so it will fit many different bore sizes.

Super clear cameras! Easy to lesrn and use. Packaged VERY well and has a nice case that I didnt even realize came with it

Small enough to fit in the fuel injector nozzle hole of a Ford 7.3 liter power stroke engine. Screen clarity and photo clarity is not as good as a Google Pixel 9 cell phone (oops...that's sort of the standard now) but decent. Sometimes the buttons yield incorrect commands. Having to twist the camera flex cord around to see 360 using side camera is very very awkward. 2 cameras, one on each side would be incredible but not possiblee at this price point.

I love the articulating head and dual cameras. I am definitely glad to have chosen the model with these features, even though it was a little more expensive. I've had a screenless USB borescope before, which required plugging into a phone or a computer, the convenience of the built-in screen on this one is also great. I have used this borescope to: - examine the carbon buildup on the valves on my direct injected 3.5 Ecoboost, just by removing the map sensor - diagnose a clogged injector on my 1.6 Miata by feeding the scope down the IAT valve opening - pull speaker wires through the walls - find a plumbing leak inside a wall The list goes on. I love this thing, worth every penny.

Work well

Fantastic scope. I have made a lot of money off of this scope. Crystal clear picture in my opinion. Articulating camera can easily see things that I couldn't before. Very happy. Downside would be that I don't think the lens is replaceable. You just have to be gentle with it.

This is one of the best scopes that anybody can buy. Taking pictures, recording videos and sharing the screen with your tablet or phone are great features. The diameter of this bore scope is 6mm which is thin enough to get into cylinder through the spark plug hole. There's another model of this brand with 3.5mm diameter but I preferred to buy this one because of the camera quality. This model has 2 Mpixels camera and it's dual camera while the thinner version is 1Mpixel camera and single. It depends what you need. I'm pretty sure the thin version has an acceptable quality as well.

Purchased for work as im a hvac tech. This camera is a game changer! Puts Milwaukee and Ridgid to shame as i used both of those long term. Camera is crystal clear and the articulation helps find defects in equipment that other cameras could never get to. The arm on the scope is very thin which is a good and bad because on one hand it can get into smaller openings and bend well but on the other hand it can also be very flimsy. App functionality is cool i wish you were able to transfer pictures to your device after already being taken, keep in mind to transfer a picture to phone u need to have the app open and be using the app to snap the picture which is alot more work to the point that i dont use that feature. Overall this camera paid for itself the first week i had it and would definitely purchase a second. Leaving only 4 stars because the camera has glitched a bunch of times now where on startup it wont activate the actual lens on the camera and ill just have a black screen, ive had to resort to holding the little reset button on the back each time and reboot it. Other wise fantastic product!

If you need to look in unreachable places this is the one. Clear image. Takes photos and video. And you can remotely manipulate the tip of the rod that has tiny bi-directional cameras and lights to look around those unreachable areas. It's like sci-fi.

Not a good tool for a shop or company poor quality broke right away wont articulate and LED light flickers. Camera was not overheated and never squeezed into super tight spots...I would have paid more money for a quality tool. Very disappointed
