A smart red dot sight with rangfinding built in
You will find a product that is the best of both worlds, it is smart red dot sight with a rangefinder built into it. there are two ranging modes, one is individual range, so if you are shooting at one target you know you're just continuously engaging taht target then you can push the button on it just like a traditional rangefinder it will shoot a laser down there and tell you how far away from you that target is. Another ranging mode is san mode which you can scan so it's continuously looking for the ranges no matter what you are pointing at, so if you are shooting at target and its telling you that it's 50 yars away from you and then you transition to target B that target maybe a little bit further from you so that rangefinder is going to tell you now you are shooting at 60 yards instead of 50 yards.
Another feature is this smart red dot sight also gives you the angle of at which you are shooting so if you are shooting at downhill and you are really have to point the rifle down that rangefinder on there is going to tell you you are shooting at you know the negative 49 degrees or if you are shooting uphill and your rifle's way up this it's going to tell you are shooting at you know 32 degrees you know what you have.
Also this smart red dot sight works good with a flip up 3x scope.
