bit off topic.. I owned the Leupold RX-2800 TBR/W Laser before I bought the 3500.com. I loved how the Leupold showed you the line of sight (LOS) to target, actual yards, and degrees. The 3500 when linked to Kestral, shows your range and holds. I liked knowing how many degrees up or down the target was; so I could figure LOS on my own.
