Default cheap borescope alternatives

hey guys

I was poking around on the internet looking for borescopes to permit images and videos of cylinder walls, valves, and piston heads. There were a couple of long discussions with lots of impressive photos on the "BeechTalk" forum. They are getting good results using cheapo cameras like these:

http://www.ebay.com/itm/NEW-6-LED-De...item19cdcd88d3

and

http://www.chinavasion.com/product_i...a-with-lights/

These cameras are plugged into a lap top with a USB connection. The BeechTalk group is building a nice archive of photos with discussion that is really useful. Mike Busch among others recommends frequent borescope use to detect damage before it causes a major problem, and as a better diagnostic tool than the standard compression test. For these prices, its worth a try

Don't bother with the boroscopes sold at Harbor Freight... you get what you pay for. Don't ask how I know...

We sell one that I tested just this week in a continental. The 9mm camera lets you get into the cylinder and the mirror lets you see the valve. It has a close focus of .4" so it works quite well. The mirror also screws on this model vs. the clip on so it won't come off inside the cylinder. 640x480 quality on a big laptop screen makes for a nicer display than the $500 model. Also works well for behind the panel and in the forward fuse interior area to see those things that are difficult without crawling in upside down. Makes push rod tube bolt inspection easy as well.

I have a small mirror on a handle that fits in a spark plug hole. I can see both valves and the entire cylinder wall with it. It has located several bad valves and a couple dozen scored jugs. No batteries, and...its in color.

The web site link says the focus is 4", not 0.4". Which is it?

I have a different take on one of the Harbor Freight items. Specifically the $199 camera/scope.

http://www.harborfreight.com/high-re...der-67980.html

The camera head isn't articulated like the $10-20,000 fiber scopes I've used in the past. But considering the price, the recording capability (video, still and audio), writes to an SD card, resolution and cordless power capability, it's a nice tool. Quality is also very good for $199.

Default Snap-On BK-6000

Mike Busch recommends the BK-6000 from Snap-On. They are going for about $500-$600 on Ebay. ($800 new) Would be good for an EAA chapter to have or perhaps to share amongst a group of owners. The BK-6000 is able to take video and pictures, store them on a SIM card for sending via e-mail or showing back at the office is needed.
Recommend listening to this webinar so that you know what your looking at through the borescope. Its called "All about cylinders" and is presented by Mike Busch. He says that if you watch the weinar you will know more than most A&Ps! Since I am one I figured I should watch it as well. Very informative.

I've caught cracked cylinders that had great compression a few times using a Lenox borescope. The cracks were hard to see even with its good optical clarity so I'm a little dubious of the effectiveness of a low-resolution camera, regardless of price.

I'm not knocking what David is saying, all good stuff indeed. Just sayin' (again) check what's being done with the cheap stuff, as posted on the BeechTalk forum. Excellent photos of exhaust valves.
