Teslong 5.5mm Slim Probe Two-Way Articulating Borescope for Automotive

So I bought this to suss out an oil leak. Found the oil leak, a leaking timing chain cover in the rear of the engine. Bummer. However, this awesome bore scope really saved the day in terms of me NOT having to pay a mechanic to suss it out. Since then I have used it almost weekly to suss out other issues, including home problem (found a dead mouse stuck in a vent pipe, damn we could have died from the backed up gas). So really, all I can say is not only has this bore scope paid for itself multiple times over, but maybe even saved our lives. So if you need one, get this one, extremely dependable and accurate and makes really crisp clear images and video. Well Done !!

Great articulating borescope and a very good value for the price. The 5.5mm camera is very slim, which allows it to fit through almost all spark plug holes and makes it great for checking cylinder walls, valves, and other tight areas. The picture quality is good, the camera works nicely, and the articulation makes a huge difference compared to a normal fixed borescope since you can actually look around inside the cylinder instead of only seeing straight ahead. Overall, it seems to hold up well as long as you use it properly and don’t abuse the articulating end. My only complaint is that I wish they included attachments like a hook or magnet for this slim model like they do with some of the thicker models. For the price, though, it’s a great value and much more useful than a basic non-articulating borescope.

This borescope is way better than I expected for the price. The resolution is excellent, the light adjustment is spot-on, and for automotive use it does everything you actually need. Don’t get fooled by all those “360° rotation” gimmicks on expensive scopes — none of the cheap ones truly look backward a full circle anyway. This one realistically gives you about 180° backward view, and that’s more than enough to inspect valves and see exactly what you need inside the cylinder. For automotive work, this scope is absolutely enough — you won’t miss anything. No need to overpay hundreds of dollars. In a shop environment, a scope like this usually lasts a year or two under heavy use. And honestly, that’s the smart way to do it — buy this one, use the hell out of it, and in two years pick up whatever new tech hits the market, instead of dropping $500+ on something that’ll be outdated anyway and you’ll hate replacing. Great tool, great value, perfect for real-world automotive diagnostics.

excellent image quality. easy to manipulate the camera, long line for deep cavities and hard to see locations.

Was skeptical at first about this borescope, but once I received it and used it for the first time I was definitely impressed by it. Decent quality overall but very clear at about 1 1/2" to 6" which is going to be the range that you're going to be using this the most. I have been most impressed by the articulating head which comes in handy all the time with the ability to look 180° from the approach angle is especially useful. The light is plenty bright for use in most situations. The 6' cable length is perfect for most jobs. You are able to take pictures and videos with it which makes showing the customer the problem easier. One of my more recent diagnosis I was able to preform because of this was a cracked cylinder wall in a block on a engine that was having misfiring issues, being able to go into the cylinder, see the crack, take pictures, and show the customer all witout taking the engine apart is a huge gamechanger. Functionality is great for most automotive and maintenance work. Good value at a reasonable price. Would definitely recommend for anyone needing a borescope.
