The Dewalt DC410 Inspection Camera. What's neat about it is that the color screen detaches from the pistol grip and the signal is then transmitted to it wirelessly. Plus, it takes JPG pics and AVI videos and saves them to a micro SD card (youtube vid at the bottom of this post). Nice flexible snake camera, waterproof, goo-proof, etc. Here are a few shots of it and by it:
This quality of the pics is not bad. Not as good as your digital camera, but not bad at all for Cobra work. Here's a typical quality shot of the solenoid:
This is a shifter bolt that fell out a few years ago and almost left me stranded. I used to have to remove the shifter boot and ring to check on it, but this is a pic of it from below with the snake camera. OK, it's still there and still tight.
Quick shot of the main ground behind the passenger side cylinder head.
Now this is what's really cool. This is a video that I took while the camera was underneath the car, pointed at the slave and fork, and I was sitting behind the wheel pushing the clutch in and holding the monitor and watching it all on the monitor while I was pushing it in (and recording at the same time). Very cool, and a lot of fun to play with. Cost: About $150
EDIT - I got it shipped to me from Lowes for $149. It is no longer available from them at that price.
