I got the Nikon 25-75 power ED82 to use at the 200,300 and 500 yard groundhog target shoots.To say I'm impressed is an understatment.....Even in very bad mirage I had little trouble spotting 6mm holes at 500 yard...In fact in one 500 yard relay I was spotting for 3 people at one time.Because the scopes their spotters were using couldn't cut.Before the mirage picked up I could see every hole in the 1000 yard backer...If someone is looking for a long range spotting scope...Take a look at the Nikon ED82..Think you may be suprised
