On my nikon monarch 1200 I have found the following. Deer-300yds facing/575-600yds broadside, large concrete columns grey/white (RR bridge) 1368yds, yes it will range beyond 1200yds, trees beech smooth white 25" dia. 938yds, oak rough brown 30" dia. 787yds these I would say are non reflective targets . All where at mid day no precipitation with no secondary interfering brush/limbs or ground rise between the unit/target. "Not useful beyond 800yds" I dont agree . I shoot a 300win. mag. with 6.5-20X leupold to a max. hunting range of 600yds and find it very useful. Monarch 1200 Brightness scale rating -10 thru 0 (0 being your un aided eye) thru +10 I give the unit a +2 which is just slighty better than bare eyes at twilight with no moon. For reference the 6.5-20X scope listed above gets my rating of +6 @ 6.5X , +2 @ 10X , and -4@ 20X. The backlit recticle feature of the monarch 1200 is to be used after ranging in low light to see the recticle and yardage/meters not during due to its being too bright and is a non adjustable intensity, on/off is your only choice there. Tip--- DONT TOUCH THE LENSES protect them. If your shooting or ranging over 1000yds then the swaro is for you but the nikon 1200 is fast and simple to use and if your shooting deer over 600yds then your my heeeero.
Pros: low cost,can range deer to >600yds,brightness
Cons: cannot change backlight intensity can only switch on/off
