In dim light/moonlight higher magnification rules. Though a fixed power scope has less lens/more light if the dif is 90-92.5 you cannot tell the difference as you need 3% to notice a change. A recent variable w/IR dot, latest coatings offers wide FOV for general panning and ability to quickly zero in magnification.

The last of two models that started the Sightron Stac line 2014, 2.5-17.5x56 IR dot was discontinued this yr. In 2015 it was offered w/4A IR red dot. Except for the rest of what's left being at least half of the price I couldn't understand its demise.

I have a 8x56 bin from the 70's. Night Owl whose hook line was, "How to see a black cat at night". Not real bad for very limited ocular/objective coating, non-phase coated roof prism w/really narrow FOV. They were MIJ mail order that sold primarily out of outdoor style magazines. If the mag had 110 pgs this ad could be found right around 106.

They definately were never the cat's meow, but they aren't novelty bins.
