PRS Talk scope illumination

Only a big deal shooting in low light conditions or from a area of high light into a dark area or with night vision.

Not essential but I used it on every stage at a recent match. Tagets were grey steel against a grey slate/shingle background on a mountainside. It was pouring with rain and vis was pretty awful. You could get by without it but on days like that it makes a difference.
 
I use it at almost every match. Shot up targets or targets at darker areas it makes it much easire to get a good sight picture on them. No reason not to have it on any scope now.
