All and all, the Deltapoint Pro is a MUCH better scope than both the previous Deltapoint and the RTS2. The scope appears to be much more robust. It has a spring steel impact shield and is made for a tactical LE/Miltiary environment. Moreover my RTS 2 has already been in service once (as many others have had theirs in service). The DP Pro stays on with motion and allegedly has a 6+ month battery life staying on all the time (if it was bouncing around in the back of a patrol car). The 3.5MOA dot is on the DP Pro is actually brighter than the RTS2 on its brightest setting and is just as visible. The quality of the glass on the Leopold seems significantly better from what I can tell. The dot also point in nearly exactly the same spot as the RTS2 (you won't have to retrain yourself). The glass is roughly the same height and appears to be wider. The new DP Pro is taller than the old one in both the height of the glass as well as the body. So even though the legacy Deltapoint may have been lower, the newer unit allows for brightness control, and replacing the battery without removal of the scope. Kinda pricey at ~$600 but not bad. Wonder how many others will make the switch.
