Swarovski Optik’s EL Range TA (Tracking Assistant) Range Finding Binoculars provides advanced range finding and glassing performance. They feature Swarovision Technology to deliver a flawless image with color fidelity and exceptional resolution with 90% light transmission and a wide field of view. Unlike most laser rangefinders that just provide distance to the target, the EL Range TA can be configured to fit your personal ballistic needs by pairing with the EL Range TA Configurator App. From there, the user can create three different ballistics profiles based on their needs. Aside from range measurement, factors including shot angle, air pressure, and temperature are taken into account and calculated allowing the user to make the most accurate assessment of every hunting situation. In addition, the Swarovski exclusive Tacking Assistant greatly assists the hunter in identifying the target area by measuring back to the point where the shot was taken. This can be preformed with the EL Range TA itself, or via the app. Using the binoculars themselves, tracking is preformed by selecting on of the last three measurements, then distance data and directional arrows will indicate how far you need to travel left, right, forward and backward to locate the target area. If cell reception is available, the user can track using the app. This is done by selecting one of the last three measurements, then simply let your phone guide you to the target area. Regardless of the method, the tracking assistant can help the hunter locate downed game by guiding them to the area where the shot hit.
