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.

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!

Well designed, works as described, good battery life, comes with a great case with clear instructions how to store the "snake" without damaging it. Image/video has good resolution. I inspected the cylinders in my old truck and could see the honing pattern on the walls. I use it for much more than DYI automotive work to get into tight spaces inside the walls in our house.

Great as described

I was very impressed with this product. I used this frequently for work as a warranty inspector. One day there was just a black screen, and no communication with the camera. I called, they said they were going to send a new one. Took 4 phone calls, despite every person saying they were going to personally expedite it. The one they sent me was a refurbished one. The boot was ripped, and it would not read a memory card, so it won't take pictures. I called, and was once again told a replacement would be sent. Once again nothing, then I was told they were out of stock in their warehouse but they would send one from the Amazon warehouse. 2 more days of no updates, and now Teslong is saying Amazon won't send one because the order was refunded. It wasn't refunded, the refund is just me getting it free because it's a warranty replacement. No one will fix this. Teslongs current solution is to send me a lower end single lens model until a new shipment of the one I ordered comes in from China. I doubt I'll see the single lens one, which is an insane offer for a warranty claim any

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.

This thing is fantastic. It has allowed me to look into cylinders, and diagnose certain things I would have never seen without the 90 degree lens. Overall, a fantastic machine. Also, the ability to maneuver, and the ability to record videos, and take pictures, is worth it.

The image quality are mediocre. Really bad compared to a cheap cell phone images. It's probably reasonable for the price and small package. The dual camera is a nice touch. Lights are bright for its purposes. Compared to my 12 year old cheap snake cam, it's only a small upgrade in terms of image quality. The articulation helps, but not a panacea for all maneuverability issue.

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
