Review on Enhance Precision with the David White D620 Sighting Level by Steve Modesto

I was pleasantly surprised to see that the spirit level is made of thick and durable aluminum rather than plastic. However, that quality was wasted as the lens was so scratched and tinted that I couldn't see anything in normal daylight. Not that it mattered as the lens fell out quickly within 24 hours. Now this is useless as the level line is marked on this lens.
