I bought a Swarovski 10x42 EL Range Binocular and sent it to a friend in Idaho to try out. He and some of his friends were at a bow competition last week end and were also trying out and comparing various rangefinders that members of the group had. My pair of Swarovski EL Range Binoculars only reached 1026 yds once and all other attempts were less than 1000yds while another pair was consistently ranging above 1800 yds. They changed the battery in mine but this did not help. They also had Bushnell Fusion Binocular Rangefinder ranging better than 1800 yds as well as Zeiss. Is there anything else to try before sending them back to Swarovski?
