Teslong 5'' Dual Lens Borescope Camera for Wall & Engine Inspection | IPS Screen 16.5FT Cable Industrial Endoscope with 7 LEDs, Waterproof Fiber Optic Snake Scope for Automotive, HVAC, Plumbing

Bought this for work because I was getting frustrated not being able to see what kind of blockages were in walls that prevented me from running cables. This thing definitely did the job. I was skeptical from looking at countless other models that were cheaper, or several other endoscopes that looked identical but were rebranded with other brand names. I decided to buy the bullet on this one, and I’m glad I did. Picture quality is excellent. It looks great, and gets the job done. I can actually make out what things are in the wall, which is even more helpful with the attached LED light at the end of the scope. Multiple brightness settings and quality settings make this a must buy for anyone who has trouble looking into tight/dark spaces. Recording on this device is also awesome. Being able to revisit past recordings is super handy, especially if you need to describe what you saw to others. The included memory card allows you to take plenty of pictures and videos as well. This product has been super helpful on the job, and saves tons of time and money. Well worth the price!

The borescope camera is outstanding. I inspect and repair RV's and this camera saved my rear end! I had a power cable get stuck way out reach in a ceiling cavity. The borescope helped me find the cord and I was able to slowly fish it out with other tools. Without this camera, the RV would have needed its ceiling dropped. The picture is adequate for the work I do. This is not a high end camera where you can remotely articulate the camera from side to side, but I don't believe I will need it because it has two camera views. I was able to take pictures and video to show the work I was doing for a customer. Very impressive. Zoom capability is modest with 1.5x but in cramped spaces, you don't need much more than that.

Very pleased with both the quality of construction and the quality of the images produced. As a serious DIYer I appreciate high quality tools. I put this endoscope in that category. During my 40+ years of experience I have learned it is typically worth the extra money to buy quality tools designed to do a specific job. Such tools typically operate with fewer problems, produce better results, are more durable, and are a pleasure to use, instead of being a source of frustration and regret one often has when buying inferior tools. I really like most everything about this unit. - The dual camera. Being able to see straight ahead and at 90 degrees, without having to use some sort of mirror attachment, is really helpful. And being able to switch between the two views without moving the probe is invaluable (obviously can’t do that if using a mirror attachment). - The semi-rigid cable. It is flexible, yet rigid, once bent to the desired shape. It retains its shape until you change it. It doesn’t flop around like many of the less expensive units do. - The high quality image produced by the camera and screen combination. The clarity is amazing and the details you can see is impressive. The images produced have been more than adequate for any inspection that I have done. - The adjustable lights built into the probe work well. They provide sufficient light for the camera to capture a clear image. In addition, being able to reduce the intensity of the light, at times, improves the image quality. The flashlight built into the hand-held unit is handy. - The simplicity and intuitiveness of the unit operation is welcomed. Since I don’t use the unit very often, being able to take it out of the case and immediately have it up and running providing images in a matter of minutes is great. Having a unit with more “bells and whistles” but one that I would have to refer to the instruction manual, to refresh my memory on how to use it, would be a real pain. Likewise, having to depend on establishing communication with a cell phone, and the inherent challenges that can come with the software on the cell phone recognizing and communicating with the camera, etc. is not a complication I need. - The case is very nice and appropriate for a professional/industrial piece of equipment such as this. Among other inspections performed, I was able to inspect my home’s HVAC ductwork to confirm the ducts were clean and free of any mold or mildew, saving hundreds of dollars by not hiring a specialty cleaning company to clean the ducts when they really didn’t need it. I cut diametrically opposed slits in a tennis ball and pushed the probe through the slits until the end of the probe was slightly protruding from the outside of one side of the ball. Then I was able to push the probe/tennis ball through the inside of the ductwork with the tennis ball keeping the probe about 1 ½ inch (i.e. radius of the tennis ball) off the surface of the ductwork. This technique worked well and allowed a thorough inspection to be performed.

Purchased this scope to hunt down a water leak in our motorhome. The first scope I Bought was a Harbor Freight scope. What a piece of junk. You get what you pay for. I searched amazon and decided to give it a try. Reviews showed people really liked it. FYI, after my own research I found out this manufacture actually makes medial scopes also. The scope showed up in two days. That very weekend I tried it out. The unit was fairly easy to figure out. the picture was amazing and all the functions worked as they should. I went to work looking for that elusive water leak. I will say while snaking it through it does get tricky to figure out the orientation. After speaking to my son who is physician assistant he told me it is all practice on knowing your distance and orientation. Well I found the leak in 30 minutes in the middle of the coach behind a support. I would absolutely recommend this scope!!! My only recommendation would be if you have a few extra bucks is to order the short scope accessory end for the unit. While the unit functions perfect with the long one the shorter one comes in handy for smaller jobs like automotive work.

My plumbing outfit is normally pretty competent but they charge $300 bucks for just about any visit and work they do. I had ** subtle ** leakage in a cramped area behind the tub in my bathroom that was dripping to the floor below. Plumber couldn't get to root cause. The camera showed me that our clawfoot tub has progressive corrosion around the underside of its drain causing leakage and that also, a nearly hidden pipe that goes up to the shower never had it's sealing ring tightened. I turn on the shower and this camera IMMEDIATELY shows the leak spurt out at a particular location - i.e. immediate cause & effect evidence. The picture is very clear. The ability to take pictures and even movies for what you find puts it over the top. * Comes with a decent case and a perfunctory owners manual. * Battery is replaceable. * I have been able to get things done without referring to the manual much. The ONLY thing that threw me off for a moment was 1) being unable to find the micro-USB port to begin charging (It's behind a skinny strip of rubber seal you can pull back) and 2) It took me a few minutes to realize that I didn't have to add a USB card as they were actually nice enough to provide a 32GB one. * The cord is pretty darn long and is very armored. Slight frustration: You'll spend most of your time adjusting and wrestling with the fiber optic cord/snake to get it just so. But that's life eh? SUMMARY: While this is my initial use, I can say that - at this point - I can recommend this product. It's one of those things where I don't envision using it but once a year but when I need it, it will come in very handy. EPILOGUE: I could have used this years ago while doing electrical work in our turn of the century older house (non standard studs) and also when I was mounting big screen TV. At that time, the way I had to gather info was circumstantial: pounding on wall, stud finder & drilling a hole or two and patching later. This device would have solved all that and saved me a lot of time.

After reviewing numerous endoscopes/boroscopes - I landed on this product. Some of the stand out features are the semi-rigid cable, the larger display, and (most importantly) the 2nd camera 90 degrees off the second. I've used/purchased other products in the past and they typically lack brightness and clarity. This product was bright enough for my purposes and clarity was good. I was looking for something where the focal length could look into a dark cavernous space and give me visibility in all directions. This product is sufficient for this task and much better than most. The standout feature that all of these cameras should have is the 90 degree opposed 2nd camera. This is critical when you enter a space like a floor joist or a void and have no ability to bend the end of the boroscope. With this easy to access camera, you can simply rotate the entire shaft and have a 360 degree view of what is going on in the cavity. The product worked well and has a case to transport it in. All pluses.

I dropped a woodruff key into an engine case and couldn't see it with the naked eye. I went to Harbor Freight to buy one of their scopes. When they refused their discount coupon to bring it down to a reasonable price I passed on it and ordered this. I'm so glad I did! This is much nicer and less money. The camera head is very small so it fit into some of the small gaps in the engine case and we were able to take a good look into all of the corners of the inside of the case. The side camera was equally as helpful - giving us views of areas we couldn't have seen otherwise. The resolution of the screen was excellent. The controls are intuitive. The storage case is nice. I'm now using this camera to check the pads on my disk brakes without having to take the wheels off of my vehicles to see them. So this has been a nice tool to add to the other tools in my garage. I'm glad to have it.

As a home inspector, my toolbox includes a variety of testing and measuring tools: screw drivers, nut drivers, framing square, concrete and wood moisture meters, temperature\humidity meters, multi-meters, GFCI & AFCI testers, infrared and probe thermometers, binoculars and a couple of really nice digital cameras to document the appearance of the residence or structure. Two hands required for a thermal temperature picture, one holding a digital IR thermometer directed at the object while aligning the camera with my other hand to “capture” the reading works well enough; however, a lightweight IR camera attachment to my cell phone is quicker and gives my client a true visual representation of temperature variance. During a recent home inspection with the house temperature set at 75 and the exterior temperature 61 (picture 1), I felt a breeze several inches away from the chipped plaster above the receptacle and wanted to know more. Placing my anemometer meter at the opening, a 3 mph wind speed was recorded, the draft I felt several inches away. A wide view of the wall was provided by the Teslong IR camera that displayed a 9 degree wall temperature difference within 24” inch span (lack of or missing insulation). Removing the cover and receptacle (outlet), I was able to easily insert the NTS300 lens for a look behind the wall. As the pictures captured, there was no insulation directly behind the receptacle box, above (bent the lens cable upward) and below using the side view camera. The red, yellow, blue, green IR picture is the outside (fiber cement siding). The exterior outlet aligns with the cold spot to the right of the interior outlet and the blue in the upper right corner is the interior outlet. I did not attempt to locate the source of the air leakage, annotating in my report further evaluation by a licensed contractor for options and cost. The nine pictures provided by the Teslong NTS300 and IR camera provide a more comprehensive visual understanding than a mere draft from the outlet. What is the water bottle for? I drilled a hole on each end, passed the cable through secured with tape making a lens “stand off” for better observation looking in HVAC duct. With the rounded bottle, I’ve gone 14 feet without getting stuck. The IR camera comes in a protective small semi-hard case, easy to use with the ability to annotate comments directly onto each picture. The NTS300 scope is lightweight and easy to use. All functions (picture, video, light, etc.) controlled by your thumb, except for the side view camera switch which is at the base of the cable. Packaged in a protective hard plastic case, with two metal latches and top and bottom foam padding cut to fit the cable, camera, USB cable and three included lens attachment options is more than adequate. A small magnet, 90 degree mirror and hook to fish wire, or “I dropped my ring in the drain” recovery tool are nice additions. Providing two options for image transfer (one via the provided USB cable or by removing the mini SD card) gives the user flexibility. As a home inspector, having a “third eye” is nice to answer any lingering questions regarding temperature and other issues: wall cavities, HVAC units, duct, vents, smoke chamber, chimney… Adding the NTS300 Teslong infrared thermal camera attachment to my tool inventory will allow more accurate reporting. Well worth the investment.

Hi. The camera is great product for the money. Easy to use in the house. I head water leak and perform very well. Enough light in dark area, picture quality is exelent. Meybe to big leans head for use in automotive.

I used in a few jobs and it saved me a lot of time and work. It needs some used to to adjust the direction and the focus. Sometimes you need to bend the camera cable to a certain shape before you inert it to make it easier to find what you are looking for but once you get the hang of it and you used the 2 cameras it is great .

The quality and function of the product as true as it advertised. Shipment waiting time are short. Overall I’m am satisfied with the product…excellent. Thank you

Very useful for inspect our machined components

Excellent bit of kit
