Varmint Hunter, I believe you brought up an interesting point, are some individual units more resonsive and accurate than others of the same brand and model? I happen to have a Bushnell 1000 that has been exceptional, it gives readings to distances that are beyond what other similar units have been capable of in a given light situation. This unit has been used so much I had to send it back for a refurbishing and it is as good as new again, When I read about guys being so happy or so discontented with their lasers I wonder if there is a performance variation from unit to unit within the same make and model. Obviously there are acceptable production specs, perhaps there is a fairly wide acceptable range of performance that we are not aware of. I guess I expect everything electronic to be of equal performance for some reason. Don't all color monitors give the same picture?? I will ask some laser engineers what variation there might be, and what is acceptable, from unit to unit. Those guys will be at the upcoming SHOT show. My Leica happens to be as consistent for producing readings as the Bushnell, and seems to be capable of slightly longer readings on most days. It is smaller and more clear, but the Bushnell is less costy and gives pretty similar performance. I believe that your info brings out the point that lasers are fussy critters that work when they feel like it, not necessarily when we really need them to. I have seen a huge variety of light conditions produce a huge range of performance. Have had overcast days when the readings were difficult to achieve period, and others where I could hit a coyote at 1100 yards. Same goes for sun, usually get lousy performance but have had some sunny days where we could read mulies at over 1000 yards. I have come to accept about 60% performance from the units, in other words if I can get out to 600-700 yards I am saticefied. This would not do for the extreme range guys but works very well for what we are doing with our .308's. I expect that there are "lemons" that get out but wonder if there is a significant acceptable performance range from unit to unit.
