Understanding the exact distance to the target before firing a critical shot is one of the most important pieces of information for hunters and shooters alike. The Steiner Optics M8X30R Laser Rangefinding 1535 Binoculars provides this critical piece of information, thanks to its built-in bluetooth compatibility. The bluetooth adapter included in the unit can be wirelessly connected with other popular range tools, such as the Kestrel 5700 Elite weather meter, providing a complete picture and a solid aiming solution before the trigger is pulled.
