Finally, an affordable borescope - Lyman Borecam Digital Borescope w/ Monitor

I have owned the Lyman Borecam for about 18 months now. When it first hit the market, I was concerned about potential quality due to the low price versus the competition. I am happy to say my concerns were unfounded and it has exceeded my expectations. It clearly shows rifling, fouling, tooling marks, etc. Though I don't use it often, it has become a valuable tool in my shop. If I had one suggestion for Lyman, it would be to make it battery powered. This would make it more convenient to use to evaluate firearms at a location such as a gun show.
