Got the Hawkeye bore scope out today mini mag lite was froze up tight. I called Gradient Lenses and up graded to the newer LED light source, This unit is adjustable and a whiter light than the mag light. My unit just made the newer threads so it would interchange.

Dealing with Gradient Lenses was a enjoyable experience. Both ladies I spoke with were very helpful and knowledgeable. The second one actual knew what the different thread pitches were between old and new.
