Using a Borescope's Magnet Attachment to Retrieve a Dropped Wing Nut
This video illustrates another useful thing you can do with a borescope: retrieve dropped hardware and other small metal objects. You can do this using the magnetic tip attachments that are available for most borescopes. It's like having a magnetic pickup tool – but one with eyes. It's one of those things that makes a borescope the tool you wonder how you ever lived without.
To understand this video, you first have to understand that the magnet attachment for my borescope blocks the center of the camera's view. This is true of most borescope magnet attachments. There are a few that use ring-shaped magnets that don't block the camera, but they also have larger diameters that limit where they can go.
Because the magnet attachment blocks the center of my view, I had to use a side-to-side motion to first find the shiny object, then get closer to make sure it was the wing nut I was looking for, and finally retrieve it with the magnet.
