Leupold's RX series digitallaser rangefinders are top performers. Some of the latest technology introduced in RX series models include 13 selectable reticles, thermometer, inclinometer, fold-down rubber eyecups and accuracy within ±1 yard. The RX-II laser rangefinder has True Ballistic Range™(TBR™). This provides a firearm or bow shooter with the correct range when shooting up or down hills. A sophisticated ballistics algorithm is applied to give the corrected, accurate value. This makes uphill and downhill shot placement much more precise. Advanced software, linked to ballistic groupings within the system, allows shooters to utilize TBR in conjunction with their reticle to more precisely determine point of aim when shooting up or down hill. Digital Instrument Panel™ processes signal information digitally in an easy-to-read format.Leupold RX-II rangefinders compact size makes for easy one-hand operation.
