5 of 5 Great Accessory and Learning Tool December 27, 2021
Reviewer: Blake from Nova Scotia, Canada  
While not a necessity, the SQM-L is a very useful tool for helping one understand viewing conditions better and finding the optimal viewing locations in their yard. Very easy and quick to use.

5 of 5 Very accurate September 19, 2021
Reviewer: Marty W. from Richmond, CA United States  
I live and most often observe in urban/suburban skies.  I was curious just how polluted my skies are and how much better they get when I travel to darker skies.  The Unihedron SQM-L closely matches the reading predicted by lightpollutionmap.info for the two locations I have checked.  Easy to use, well built.
