?? It would seem odd to purchase a real time ballistic calculation scope to not buy the components necessary to make if 'real time calculate'. This being said. The "leave and forget multi point" feature is not what I'm talking about.No you don't. It has ballistic holds built in if you don't want to buy or use the rangefinder. I have mine set up using them for 20-30-40-50 yards.
The feature that I use is a single dot that moves every time you range. It's a single point. I don't like the multiple points. That's nothing more that the electric version of the factory scope.
I also like to know my exact range to target and surrounding POF objects, but that's coming more from the rifle world and long distance shooting.
