this is perfect to get out a throttle body red straw out from down all the way to my valve intakes into my pistons on an 04 colorado pick up, the worm head tilts to lead it down turns, it sees and photos out front or side camera perfect. adjustable lighting and focus, but i used bright light and normal focus. the straw looked big and very bright to my eyes and on photos and not sure, i tried a video but i didn't do it right, but im sure with better knowledge the video would have been awesome too. it is a no brainer right out of the box, has it's own micro sd card, own charge wire, just straight up top of the line with a bottom of the line price...and it looks like it won't come apart in a tight spot in the engine... be gentle with it...you must leave the unused part as straight as you can while the used part, i used abouty 17" only gets turned and the total off all bending has to be less than a full circle, i only used about little over than half a circle maybe. i used a clear vinyl tubing cut to 16" fort 16" to go down past the throttle body inlet to get near the red stick and then i snorkled the camera snake back in again and saw the red stick and then my tube finally apporaching close to the red stick and cranked up the vaccum shop vacc all linked from a 3" fat suction stub on the vaccum reduced down to the 1" od clear tubing that snaked into near the valves and in a few minutes it sucked out the nasty red straw stick out of my engine...a intake manifold dissassembly on a 20 year old truck would havce cost maybe thouseands.... this job cost me 150 or less bucks and done in less than an hour and the truck is perfect again...i even could havec inspected allmost all of my valves if i'd wanted to and my cylindeer, but i gave the thing away to a farmer with lots of tractors.......get this borescope please, very affordable and so professional.....do yourself a favor....

Cool toy and works fantastic! Great clear color image. I dropped a tiny guide sleeve while servicing my Yamaha outboard's fuel injectors - couldn't find it on the floor after lots of searching. So, a tiny chance of ruining a $15000 outboard or buy this thing for $135 (it's actually cheaper as of this writing) and make sure it didn't fall into a cylinder? To me, a no brainer. The guide sleeve wasn't in there - but I put together my outboard and ran it without worry. And that's a good deal! Read more
Great scope in every way. I bought a 2003 Suzuki Grand Vitara in over all good shape to use as little 4x4 for dual sport use. It has very reasonable miles on it. I discovered it was going thru a quart of oil every 200 miles with almost zero leaks. I thought I had been really screwed but hoped it was valve seals. I wanted to check the cylinder walls for excessive wear and scoring before doing anything. I looked at a lot of these scopes and settled on this one for a number of reasons. I liked the side camera. I found that this unit is so good it is not needed. These all have internal batteries which die over a period of years. This unit can be run off a USB-C phone charger or an emergency battery for recharging a phone. That means that as long as the electronics work, it is good to go. It comes in a very professional carrying case and special hooks and stuff to attach to the end of the camera. Excellent light brightness. Excellent video quality. Focal length is from around 3/4 inch to 100 ft or more. Over all picture quality is bright and crisp with great resolution. I could count the factory cross hatch marks on the cylinder walls. Flex Tip. Just over 180 degrees. I was able to look back at the bottoms of the valves. The flex function works very smoothly. The info I gained was worth the money I spent. I could see that I have no burnt valves, piston tops looked good with a thin layer of carbon from the oil and the cylinder walls are in new condition. I decided to try some AT-205 to see if it would soften the valve seals before having them replaced. If that worked, I know the rings are likely good. It did nothing for the first 300 miles. Suddenly after letting it set for a few days, and then starting to use it again, the oil on the dip stick seems to have almost completely stopped dropping. I calculate I am now up to at least 400 miles per quart if not a lot more. There is no more smoke at cold start up or after idling for 5 minutes and taking off in a hurry. Read more
